The episode begins with the School Bus arriving at the Wattersons' house. Rocky asks Gumball about why the long face, in which Darwin replies that he tried to stretch his face to make himself look too old for school, but failed when Nicole saw his trick, and Gumball points out that his day was in fact gloomy, then, they enter the school bus as it "drives" off to school. Rocky explains that he doesn't know how they always go to school everyday, and as Gumball points out that he obviously always drives them there, Rocky says that he doesn't have to drive them to school. Gumball, looking back with relief (and accidentally hurting his neck), he questions if the fact that Rocky doesn't need to drive them to school is true, and Rocky replies yes and the fact that since they are on the bus, they could go anywhere. This makes everyone happy and gets ideas where else to go, such as Darwin saying they could under the sea, and Alan points that they should go to school but as he continues to talk, Gumball pops him. Eventually, as Rocky decides to skip school, everyone agrees on going to the water park, and that Rocky says that there is one more stop, as Rocky stops the bus to let in a few people. As the Bus goes near a bridge, Banana Bob, disguised as a criminal, stands on the bridge and uses binoculars to see the bus, and as he attempts to jump to the bus, he falls to the ground, as he discovers he was using the binoculars the wrong way, he gets ran over. The people that entered the bus, seem to be everyone's parents also disguised as criminals, but nobody notices this except Gumball. They point out that they are not going anywhere, as Richard uses a briefcase to scare everyone except Gumball, and that the briefcase has a bomb in it. Gumball tells everyone that they are just their parents trying to teach them a lesson, and he points out Principal Brown hasn't even changed his name, in which Brown attempts to reply that he did.
Principal Brown gets a message from his phone and reads out as if it was their plan, that they will call the police and tell them that they will take control of the bus and will not release the students until they reach their demands. Brown tells Harold to make the call, but they planned to disguise his voice, so Dexter inflates Harold's mouth to make him sound different. As Harold calls the police to inform that they have taken control of the bus, Gumball asks Alan if he recognizes his dad, in which Alan does recognize, but he claims it was someone he saw last night on TV at his house. Gumball, again, tells him that it is just their parents, as he gives a example of when "Richard taught them the dangers of texting while walking." The disgusted parents start making the whole plan from text messages on Harold's phone, and they plan to ask the police for money. Darwin soon tries to find a way to "stop the criminals with a leader", as Gumball decides to be the leader. He walks up to his dad Richard and speaks, as Richard claims he is "Mr. Pink", Gumball tries to tell the truth as he argues with Richard, with him saying his fake criminal life, as everyone else speaks to Gumball as a "criminal".
The police soon arrive near the bus, as the Doughnut Sheriff starts handing over the ransom, but as he goes to the school bus in which he goes too close and ending up breaking the window, he unsuccessfully throws the briefcase which causes the police cars behind him to crash together, then the sheriff orders a second briefcase of money with their demands doubled. Police that are in the area ahead the bus place a second briefcase on the road. Richard reaches out to get the money, only to realize that this was supposed to be a trick and the police noticed the that bus is heading for the airport. Darwin suddenly orders the kids to hold and subdue the parents. The students take off the masks and are surprised (except Gumball) to see that they are their parents all along. Principal Brown also realizes the the first briefcase they have has a bomb in it then everyone screams in fright. Then they all turn around and are shocked to find Rob on the bus too. He told everyone that it was his plan to suggest the plan to Principal Brown, trick the parents into stealing a million dollars, and to blow up the bus. Gumball asks why, Rob replies that he is Gumball's and Darwin's true nemesis. Then the bus gets close to the airport but the bus goes over a speed bump throwing everyone in the air. Rocky apologizes but before he could finish, he collapses unconscious, the money slides to Rob. Gumball and Rob fought seriously and fought good as the bus drives to the runaway airplane, The airplane director sends the out of control vehicles in different directions. Then suddenly, another plane comes in for landing only to see the out-of-control bus approaching towards it. Everyone screams as the plane goes back up before hitting the bus, and as Rob and Gumball are fighting, the police enter the bus, mistakenly arresting the now undisguised parents. Rocky wakes up to find that another plane is heading for the bus, as he jumps out of his seat, and the wing of the plane hits the roof of the bus, as everyone ducks.
Everyone is still seen on the bus, except for Gumball and Rob which are still fighting with the two briefcases, on the wing of the plane. As the fight on the flight continues, Rob hits Gumball as he falls to the ground, but when Rob is about to smack Gumball with his briefcase, the police arrive, in which Rob acts like he was being threatened by Gumball's "ticking" briefcase, in which the police fall for it and arrests Gumball as Rob runs away. The parents correct the police's misunderstanding and releases Gumball, but they realize Rob ran away with the money, then it is revealed that they had the briefcase with the money, and that Rob has the briefcase with the bomb, as it explodes, sending Rob flying to the police car, as he is under arrest, then the episode ends.
Banana Joe is sitting behind Gumball and Darwin on the left side of the school bus, but after Gumball asks everyone where they'd rather go instead of school, Banana Joe is suddenly sitting on the right side of the bus, behind Tobias, where Sarah was sitting.
Dexter lost his hat after his failed attempted to get the briefcase but gains it back after Richard grabbed the briefcase.
When Banana Bob is looking through the binoculars on the bridge, his left eyelid is transparent.
In one scene, Gumball pops Alan. But he appears throughout the whole episode.
Clayton appears at the back of the bus in the beginning of the episode, but vanishes after the parents come on the bus.
There are several scenes where the kids don't appear in the back of the bus.
The 3D models used for the bomb and money briefcases are switched multiple times.
Rocky: Hey guys! Eh, why the long face? Feelin' gloomy?
Darwin: One, his face is long because he tried to stretch his skin to make it look like he's too old to go to school. Two, no, Mom didn't buy it.
Gumball: And three, yes, I'm feeling gloomy.
[Gumball and Darwin get on bus, and Gumball trips on his own face, then the bus drives off.]
Rocky: Oh, man, I don't know how you guys do it.
Gumball: Eh, it's not that difficult to learn how to stretch your face. There's an online tutorial for everything now-a-days. [to Leslie] So, did you finish...
Rocky: No, I mean I don't know how you go to school every day.
Gumball: Rocky, you drive us there.
Rocky: Well... I don't have to.
Gumball: [grinning] Reeeeaaaalllyyyy....? [neck cracks as he turns his head] Aah! Aah...
Rocky: Well, we're on a bus. We could go anywhere.
Darwin: [excitedly] Like under the sea, or to outer space, or up a rainbow?
Rocky: Well, anywhere with a road. But not up steep hills... or under low bridges.
Gumball: Let's do it! After all, we've got the rest of our lives to go to school.
Alan: Well, I think we should go to school, so we can work hard and get the best possible start in li--
Gumball: [sighs][walks over and pops Alan off-screen] Anyone else wanna go to school?
Gumball's classmates: No, no, no no no...
Rocky: Okay! No school it is!
[The bus drives past school]
Rocky: So, where should we go instead?
Tobias: The beach!
Sussie: The school bus!
Darwin: We're already on the school bus!
Sussie: [ecstatically] Ya-hah!
Gumball: What about the water park?
[Gumball's classmates chatter in agreement]
Tobias: Aww, the beach!
Rocky: All-righty, we just gotta make one more stop.
[The bus stops and the door opens]
Rocky: Is that all of you, Mr. Pink? [winks]
Richard: [off-screen] Almost. Looks like Mr. Yellow didn't make it.
[Bus door closes, the bus drives off]
[Banana Bob looks on from overpass]
Banana Bob: [chuckles sinisterly] Why catch the bus when the bus can catch you?
[Bob jumps from overpass but lands on road]
Banana Bob: Uh... the binoculars made it look closer than it was. [looks through binoculars backwards] So I guess it's still quite fa--
[Bob is run over by the bus.]
Banana Bob: Ugh...
[On the bus, the students are still discussing the destination]
Gumball: [to Tobias] Alright, we'll go to the water park, then the beach!
[Tobias opens his mouth to protest, but a foot stomps and startles the students]
Principal Brown: [clears throat] Good afternoon, children, my name is Mr. Brown. This is Mr. Pink, Mr. Rainbow, and Mr. White, and we'll be your captors for the day. The exits are... [loudly] irrelevant, 'cause you're going nowhere!"
Richard: Nobody moves, or I'll be forced to use this! [holds out briefcase]
All students but Gumball: [gasp] It's a briefcase!
Richard: [ticking sound comes from briefcase] No, more than that.
All students but Gumball: [gasp] It's a ticking briefcase!
Richard: No, more than that.
All students but Gumball: [gasp] It's a bo--
Richard: [panicking] No no, no no no no no, less than that!
Principal Brown: Uh, yes, we are legally obliged to say it's not one of those.
All students but Gumball: Oh my gosh, they've got a b-- [cut off by sound of bus]
Gumball: [sighs] Oh, come on guys. It's obviously not a bo--
Banana Joe: But it's ticking!
Leslie: And masked strangers have taken over the bus!
Gumball: But they're clearly our parents trying to teach us some sort of lesson! Principal Brown hasn't even changed his name!
Principal Brown: Yes I have! I-I mean he has. I-I mean he hasn't...I mean...who is this 'Principal Brown?'
Richard: [whispering] You are!
Principal Brown: Shh! [phone vibrates] Oh, uh, yes... [reading text] We are going to call the cops and tell them we won't release you until our demands are met! Make the call, Mr. Rainbow.
Harold: [whispering] I thought we were gonna disguise my voice!
Principal Brown: Um...
Dexter: [sighs]Alright. [blows air into Harold's mouth]
Harold[high-pitched voice] Hello, police? We have taken control of the school bus, and you'd better do what we say, or [voice deepens] there'll be consequences. Oh, sorry... [Dexter blows air into Harold's mouth again][high-pitched voice] or there'll be consequences.
Gumball: Oh, come on, Alan. You're telling me you don't even recognize the balloon?
Alan: Wait...I do recognize him.
Alan: I saw him in our house last night!
Alan: On TV. Elmore's most wanted.
Gumball: [sighs] It's just our parents trying to teach us a lesson. Like when my dad tried to teach us the dangers of texting while walking.
[cut to Gumball and Darwin, walking around a manhole and texting, with Richard inside]
Richard: [fake-sounding voice] Help me! I've fallen down this manhole because I was texting while walking!
[Cuts back to the bus.]
Gumball: Darwin, you can't seriously be scared of these guys!
Darwin: Of course I am! They're criminal masterminds!
Richard: (to other adults) I just think it would be fun, I've never been in a hovercraft.
Dexter: No, we should ask for a private jet. They always ask for a private jet.
Richard: Could it be a private hovercraft?
Harold: [phone vibrates][reads text] We need to ask for money!
Principal Brown: How much?
Dexter: It doesn't matter, the police know this is all fake!
Gumball: See, they're not scary.
Darwin: [determinedly] You're right! We just need a leader to reason with them. [dramatic music plays] Someone brave.
Gumball: [clears throat]
Darwin: Someone who's not afraid to look the enemy in the eye!
Darwin: I would say you, Gumball, but you're obviously sick. Hm... maybe Leslie.
Gumball: No! Me! I'll do it!
Richard: Oh, but hovercrafts are... [Gumball taps on Richard's shoulder] Hm?
Gumball: Uh, Dad?
Richard: It's Mr. Pink.
Gumball: [unimpressed] Fine, Mr. Pink. I know it's you, Dad.
Richard: Uh... [nervously] I've never heard of this 'dad' of whom you speak. I'm just a criminal. How did I become a criminal, you ask?
Gumball: I didn't ask.
Richard: I suppose it all started when I was eleven years old and skipped a math class.
Richard: And for this crime, the punishment was harsh and swift. I spent twelve years in juvie, then five years inside, then twenty-four years on the run, then thirty years back in the big house, then a further seven in solitary.
Gumball: That makes you eighty-nine. That doesn't add up.
Richard: [laughs] Well, I wouldn't know, 'cause I skipped that math class.
Gumball: Sure. So, I assume you all ended up in a life of crime through skipping school?
Principal Brown, Dexter, and Harold: Uh-huh. Yeah. Mm-hm.
Principal Brown: Well, uh, my tragic story starts on the right side of the tracks, but boy, it sure doesn't stay there.
Gumball: Yeah, yeah, we get it.
Principal Brown: But I learned the whole thing! Don't I get to... ohh... [disappointed]
Gumball: See, I told you. It's a load of hooey.
[Siren sounds come from outside, and a fleet of police cars pursue the bus]
Doughnut Sheriff: Take the awheel and get me closer! [climbs out window] Closer... closer... closer! [through speaker] We are willing... [breaks window] Okay, too close. [car backs away] We are willing to meet your demands! I'll throw the money over in three, two, one... [throws money, misses, hits police car]
Police Officer: Aaaagh! [cars fly out of control]
Doughnut Sheriff: That one's gonna hurt the taxpayer. Control, we need another million dollars.
Control: They doubled their demands?
Doughnut Sheriff: Uh, uh... yeah! They doubled their demands! Uh...
Principal Brown: Wow, they're really going big on this.
Dexter: If only they responded this fast to real crimes.
Doughnut Sheriff: Where do you want the money?
Principal Brown: [phone vibrates][reading text] Leave the million dollops of unmasked bulls on the cold desert toad!
Principal Brown: Oh, sorry, auto-correct. Leave the million dollars of unmarked bills on the old desert road!
Doughnut Sheriff: All units fall back, ahead of second drop-off.
[At an old desert road, The bus approaches]
Hamburger Cop: Any sign of him, chief? I'm cooking out here.
Coffee Cop: They're on their way. Make the drop.
[Hamburger Cop leaves briefcase on road]
Dexter: Okay, you hold onto me, and I'll reach out and grab the briefcase! [goes out bus door but gets caught in wind] Maybe we should switch!
[Richard leans out and grabs the briefcase]
Harold: Did you get it?
Richard: [briefcase in mouth] Uh-huh.
Harold: [on phone] Okay, we have the money. Now we don't want to see any red lights between here and the airport.
[Lights on street all turn green, and Doughnut Sheriff notices]
Doughnut Sheriff: They're heading for the airport! We've gotta take 'em down! [loud voice shatters french fry cop]
[Police cars crash into one another as they chase the speeding bus. The 'hijackers' open the briefcase and discover real money]
Richard, Principal Brown, Dexter, and Harold: [gasp]
Dexter: Wait, this wasn't supposed to be real money!
Richard: It was just a trick to teach the kids a lesson!
Gumball: Well, I guess the lesson you've actually taught is that crime does pay. Well done, chaps. You've done good.
Darwin: GET 'EM!
All Students but Gumball: AAAAGHH! [attack and subdue adults]
Alan: We got 'em!
Alan: And now to reveal their true identities! [students remove masks]
[The person in the mask is "revealed" to be Richard.]
All students but Gumball: [gasp]
Darwin: They were our parents all along?!
Richard: [guiltily] You've got me, it's true. I am Richard Watersonnn....nn's EVIL TWIN BROTHER!
Gumball: Give it up, Dad!
Richard: We just wanted to teach you that skipping school isn't cool or exciting.
Gumball: By involving us in a million-dollar high-speed police chase, which is probably the most cool or exciting thing we've ever done?
Principal Brown: Yes! But we thought it was all going to be pretend! Hang on... if the money's genuine, then the cops are for real... [holds up ticking briefcase] does that mean this is a real...?
All: [scream in terror]
Gumball: Whose insane idea was this?
Principal Brown: [phone vibrates][reading text] Stick to the pan, or everyone dines.
Rob: Darn auto-correct... stupid thing never works. [stares at class awkwardly]
Gumball: [gasps] Rob?!
Rob: [sarcastically] Oh NOW, you remember my name! It's Dr. Wrecker to you, and yes, this whole thing was my idea! All I had to do was suggest the plan to Principal Brown, make sure the police thought it was real, and switch the briefcase for something a little more, shall we say...explosive.
Gumball: But why??
Rob: Because... I... am... your... NEMESIS! And also for the money...
[The bus drives quickly over speed bump, throwing everyone into the air]
Rocky: [dazed] Sorry, it's kind of hard to keep your eyes on the road when there's a crucial plot twist happening in the back of your bu--
[Rocky passes out on the wheel. The bus begins driving wildly, and the money slides to Rob.]
Gumball: The money!
Rob: [laughs sinisterly]
[The Bus begins veering out of control as the adults try to wake up Rocky]
Doughnut Sheriff: Woah! These guys are pros! They must have one heck of a wheel-man!
[The adults continue trying to wake Rocky as a helicopter attempts lowering a cop onto the top of the bus]
Cops: Go Go Go!
[The Cops break through the bus windows.]
Hotdog Cop: You are under arrest!
Principal Brown: It wasn't us, it was him!
[Rocky wakes up in time to see a plane crash into the bus, tearing off the roof and taking Gumball and Rob with it]
[Gumball and Rob continue fighting on the wing of the plane.]
Gumball: Thanks man, fighting on the wing of a plane is way more fun than math class!
Rob: This isn't supposed to be fun!
Gumball: Wait, what? Th- then why are you doing this?
Rob: Because I'm a villain! What choice do I have? All I've got on my resume is laughing maniacally, monologging about evil plans... I've got a major in Canadian History, which I'm not exactly going to go into vocationally! [Pushes Gumball off the plane with the briefcase.] And now, Gumball Watterson! Prepared to be wrecked! [The cops come running towards them.] Oh, officer! Help me! He's got a ticking briefcase!
Gumball: Oh, come on, these are professional law enforcers. As if they're gonna fal- [They put handcuffs on Gumball.]
Doughnut Sheriff: You're coming with us!
Gumball: [grunting] No, no, wait!
Principal Brown: No no, not him. The other one. [points to Rob]
Gumball: [gets off the ground] It's too late now! He's gone away with the money.
Richard: No he hasn't. That's the money. [Points to the briefcase on the ground.] It's got my teeth marks in it. [Gumball opens it.]
Doughnut Sheriff: Ah, We got the money back. He got away but my shift's done in five minutes so shall we say case closed? [Closes the briefcase]
Gumball: But, If this is the money doesn't that mean that Dr. Wrecker has the--
[An explosion happens in the background.]
[Rob gets blown away and his face hits Doughnut Sheriff's car.]
Doughnut Sheriff: Well there's only one thing left to say. You are--
Rob: I know I know, I'm wrecked.
Doughnut Sheriff: I was gonna say you're under arrest.
Rob: Oh yes, that makes more sense.
[Rob slams his face into Doughnut Sheriff's car as the episode ends.]
