The episode starts with Gumball and Darwin using their imagination to mimic a game they lent to Tobias in the backyard. Unfortunately, the laws of physics in video games differ from those in real life. This becomes evident when, upon collecting the "wings" power up, Darwin is still unable to fly. After a few painful attempts at flying over a wall, Gumball gets frustrated and urges Darwin to try harder. Darwin complains that breaking the laws of physics is difficult, to which Gumball suggests that he just grow wings in the same way he grew legs. The argument ends with Gumball mashing the crouch button. Darwin, somehow connected to the controller, is forced to comply. The crouch button gets stuck, sticking Darwin in an infinite loop until he crashes. Gumball reboots him and expresses his disappointment in using their imagination to play a game. Darwin, cheerful as ever, is hopeful that Tobias will fulfill his promise and return their game tomorrow.
The next day, upon approaching Tobias about their game, he nervously explains that he forgot to bring it. The same thing happens for the next several days, with Tobias constantly promising to bring it the next day. After a while, Gumball gets fed up with waiting and ponders alternative methods to get the game back. He decides that war is their only option. He turns to Darwin, asking him to follow him into battle. Darwin, however, wants to lead instead of follow this time. Gumball scoffs at him, causing Darwin to drop the issue.
At the library, Darwin complains about how people keep sending him e-mails to Gumball's inbox instead of his own. Gumball does not think that is a big deal, so Darwin takes him to a classroom and shows him the yearbook. In the yearbook, Darwin's profile is recognized as nothing more than a subordinate to Gumball, instead of his own person. Gumball still does not see the issue, so Darwin literally carries him over to the hall. Darwin asks one of the Eggheads if he recognizes him, and he is surprised that "Gumball's orange bag" can talk. Gumball claims he now understands Darwin's problem, and concocts a plan to retrieve their game.
Later that evening, the boys visit Tobias's backyard in order to break in his house. When Gumball asks Darwin to help him get through the window, Darwin backs out because of his being "demoted from a sidekick to a footstool." He deserts Gumball, who has fallen into the cellar. Gumball keeps calling out for his aid in vain.
The following day, Gumball approaches Darwin at lunchtime, hoping the sidekick issue has been put aside. When Gumball asks for tater tots and fish "on the side," Darwin has had enough. He storms out of—and eventually back in—the cafeteria, as Gumball follows him, trying to alleviate the situation. This leads to them mocking each other. Finally, Gumball offers Darwin a chance at being a leader, and Darwin is overjoyed.
However, Darwin's plan to get the game back from Tobias goes awry right from the beginning. Gumball is shocked that Darwin has actually kidnapped Tobias' mother, who is blindfolded and bound to the swivel chair. He tries to back out, but it is revealed that Darwin has accidentally signed both their names on a ransom note left at Tobias' house. Faced with no other choice, Gumball reluctantly has to aid Darwin.
As the boys push the bound woman up a steep street, Gumball keeps assuming the leader position when he is supposed to be the sidekick. They get into a heated argument about Darwin's poor leadership. They play pretend battle with each other, while they inadvertently let Tobias' mother roll down the street. Once they realize what just happened, they chase after her, narrowly saving her from being run over by a large truck. They all land on somebody's lawn, and they discover they have to walk through the public area.
Gumball and Darwin roll Tobias' mother through the mall, under the pretense of charity. They manage to avoid suspicion from passersby, although Mr. Small tries to donate to their "charity." Next, they try to sneak past Doughnut Sheriff in a police car. When he cries out, the boys fear they may have been caught. It turns out Doughnut Sheriff is off duty, and he is snacking on some peanuts.
Eventually, they all arrive at Tobias' house, and once again Gumball comments about Darwin's poorly thought-out plan. He claims that if it was his plan, he would have Darwin stop him. He calls Darwin not his sidekick, but his "guardian," and Darwin is touched. They make up, right when Tobias appears out of his house. They kick his bound mother out of sight, and Tobias explains that his mother has cleaned his bedroom earlier and that the game is nowhere to be found. He wonders where she has gone, and Gumball declares that Tobias can keep the game.
This is the third episode in which one of the major characters has no speaking role. In this case, it is with Jackie. The first time was in "The Club," in which Ocho did not speak, and the second time was in "The Date," where Mrs. Fitzgerald did not speak.
The game pad Gumball uses to control Darwin is similar to the controller for the SNES.
When Gumball resets Darwin, a beep similar to the Game Boy start up sound can be heard.
When Darwin lines up at the cafeteria, only Leslie is in front of him. Despite this, Rocky calls out "next" twice.
When Gumball and Darwin were strolling Jackie below the Doughnut Sheriff's car, the eyes and mouth drawn on her mouth and blindfold disappeared, yet, it reappears in the next scene.
When Mr. Small chases Gumball and Darwin, Neck Beard is seen in his normal outfit. In the next shot, he is in his jogging outfit.
[The episode starts in a candy wonderland game where Darwin is collecting sweets. Then, he gets a power-up, and grows wings, but, he can't fly over a wall ahead. The scene changes back to reality as Darwin is using badminton rackets as wings, and tries to "fly" over the "wall," which is actually the shed, but fails repeatedly]
Gumball: [He's furiously pressing buttons on a controller] Why aren't you flying? I'm pressing the right buttons!
Darwin: Because, no matter how loud you shout, I still can't break the laws of physics!
Gumball: Then, break the laws of biology! You managed to grow legs, just put some effort in, and grow some wings!
Darwin: Well, maybe you should be better at controlling me! [He angrily throws the rackets onto the ground]
Gumball: How's this for better?
[Gumball starts spamming the "down" button on the controller, and Darwin starts crouching up and down repeatedly]
Darwin: Ah! Dude, stop, I'm getting breakfast in my brain!
Gumball: [He starts examining the controller] I had stopped! I think the crouch button is stuck.
Darwin: Well, fix it, or, we will never get the high- [The "game" crashes, and Darwin crouches up and down uncontrollably] score score score score score score score score!
Gumball: Aw, man, you crashed! [Gumball presses some buttons on the controller] Reboot.
[The sun goes down, and becomes the moon, then changes back while Darwin stops crouching]
Gumball: [Gumball scoffs] Using our imagination is lame.
Darwin: It's ok. Tobias said he'd give back the game tomorrow!
[The school bell rings. Gumball, Darwin, and Tobias are on the playground]
Tobias: Oh, uh...Sorry, dudes, I totally forgot. I-I'll bring it in tomorrow, I swear! [Tobias walks off]
[The next day. Gumball and Darwin angrily approach Tobias in the hallway]
Gumball: So, did you remember the game?
Tobias: [Tobias inhales sharply] Sorry, dudes. I'll totally bring it in tomorrow.
[The location changes numerous times as Tobias makes more and more excuses for not bringing Gumball and Darwin's game back]
Tobias: Mm...I am so sorry. I-I'll bring it in tomorrow, I pro- Oooh, I'm so- Mm. Ah...I- Mm, mm- Ah- Oh, oh, oh! Mm...Ah, ah- S-s-s-sorry! Ah- Tomor, tomor- Tom-mor-or-orrow! Mmm...I-I-I-I...Mm, mm, mm, mm, mm, mm, mm, mm, mm, mm, mm, mm...
Gumball: Dude! You've done this for so long, now, even your little "sorry" sounds are all the same!
Tobias: Oh, sorry. You thought tomorrow was today; I meant tomorrow tomorrow. I'll bring it in tomorrow, I swear! [Tobias laughs] See ya!
Gumball: Okay, let's analyze the situation here. He's abusing our patience, retaining our property, and all civilized methods to deal with this problem have failed. I think we have ourselves a case for a war. Are you ready to follow me into battle?
Darwin: [In a nervous tone] Um, actually, you know what? I thought maybe I could take the lead this time...
Darwin: Yeah. I'd like to have a try at being the leader.
Gumball: [Gumball laughs at Darwin] Why?
[Sad violin music starts to play as Darwin begins to sob]
Darwin: Uhh...'Cause sometimes, I look at myself in the mirror, and all I see...is nothing but a sidekick!
Gumball: Hold on a second. [It turns out the violin music was coming from Leslie nearby, and he shuts the door] Sorry. What were you saying?
Darwin: [Darwin sighs] Nevermind...
[The episode then cuts to Gumball and Darwin playing on computers in the library. Darwin clicks on something, and it makes him angry. The computer makes a "ding-ding!" sound as Darwin clicks]
Darwin: [In a furious tone] DAH!
Darwin: Look! More proof I'm your sidekick!
Gumball: Are you still going on about that? Look, you get loads of emails! "Hey Darwin," "hi Darwin," "hello Darwin."
Darwin: Yeah, but this is your inbox! People didn't even think I've got my own email address! You wanna see mine?
[Darwin shows Gumball his email inbox. It appears to be very old and damaged. A cockroach can even be seen crawling inside of it]
Gumball: Eww... [He tries touching it] What the? Is that cockroach inside your inbox?
Darwin: See what I mean?
Gumball: Some people send me your emails. It doesn't make you my sidekick.
Darwin: Oh yeah? Then what about... [Darwin wheels Gumball to Miss Simian's classroom, bringing the school yearbook along with him] The school yearbook! [He flips open a page] That's your entry...and that's mine! It's not even me! It's a photo of your shadow! I'M. YOUR. SHADOW. And look! "Darwin Watterson. Age: two years younger than Gumball! Class: the same as Gumball! Most likely to be: standing next to Gumball! Even my nickname is "Gumball's sidekick!" [Darwin shoves the open book in Gumball's face in the process]
Gumball: Chill out! It's just a yearbook! No one actually thinks that!
Darwin: Then, how do you...explain this? [Darwin grabs a nearby student in the hallway, and confronts him face-to-face] Hey you! Look me in the eye and tell me you don't think I'm Gumball's sidekick!
Colin: [He gasps] My Rubik's cube, you can talk! I always thought you were Gumball's orange bag. [Frank then walks off]
Gumball: Oh, that reminds me. Can I have my math book?
Darwin: [He finally calms down] Oh, sure. [He takes Gumball's math book out of his mouth, and gives it to him] But, you see what I mean, though? It's like I don't even exist without you.
Gumball: [He comforts Darwin] Darwin, you do exist, and I understand how you feel. So, we're gonna get that game back as equals! Now, follow me and do everything I tell you!
Darwin: Okay, great! ...Aw, man!
Trying To Sneak In
[Gumball and Darwin are at Tobias' house at night]
Gumball: Perfect! Tobias left his window open! We just have to sneak in, and get our game. Now, bend down.
[Darwin acts as a pedestal for Gumball as he tries to climb in the window]
Darwin: See? This is exactly what I'm talking about! If I'm not your sidekick, then why are you always using me for stupid things like this? If you owned a ladder, you wouldn't need me here at all!
Gumball: Shhh! At least a ladder would know how to shut up when it's helping me to sneak into someone's house!
[Darwin huffs angrily, and he walks into the opposite direction. The window closes in on Gumball's hands, and he falls into their basement]
Darwin: That's for demoting me from a sidekick to a foot-stool!
Gumball: Okay, okay! Point taken, now get me outta here!
Darwin: I'm sorry, but I don't take orders anymore. [Darwin walks home, and leaves Gumball behind]
Gumball: Fine, you're not a sidekick! You're an assistant! I mean, a deputy! Ugh, you're my vice Gumball! [Silence ensues] Dude, you there? You're not speaking to me to make me think you left, right? And if you did, it's just to get some rope? [Another moment of silence occurs] ...You're getting rope? [Again, no answer] Nah, I'm sure he's just gone to get some rope.
[We then cut to the cafeteria. Rocky is serving students food, Gumball and Darwin included]
[Gumball and Darwin are next in line]
Gumball: So...last night, huh? Things got a little...[Gumball hisses][Inaudible] But, seriously, it's good we're all back to normal now. Same...you know...dynamic. [Gumball offers a high-five from Darwin. Instead, he high-fives himself] Right?
Darwin: I meant what I said.
Rocky: What are ya having?
[Before Darwin can speak, he is interrupted by Gumball]
Gumball: Can I get some tater tots and fish? Oh, put the fish on the side.
[Darwin suddenly becomes enraged. He throws his tray down on the ground, and storms off]
Gumball: I meant on top! Put the fish on top!
[Darwin bursts through various doors through various hallways as Gumball tries to talk to him]
Gumball: Dude, why are you so angry with me?
Darwin: Because it's your fault. You made me like this.
Gumball: What, a fish?
Darwin: No, a sidekick. Is this some kind of...[They walk through a quite long hallway, and Darwin holds his sentence. He finally reaches another door]...joke to you?
Gumball: Of course not, but do you ever think you brought this on yourself?
[Gumball and Darwin realize they just went into a circle. They are back in the lunchroom]
Darwin: This conversation is getting us nowhere.
Gumball: Yeah, you're right. So, let me demonstrate why people think you're a sidekick. [Gumball starts acting happy and optimistic, speaking in a high-pitched voice as well] "Hey, I'm Darwin! Oh, your shoes are dirty! Looks like you could do with a door-mat!" [Gumball forcibly rubs Darwin's shoe on his face with that happy look still on his face] "Hello Gumball! Do you mind holding my hand for my entire life?! What are we gonna do? Where are we gonna go? What are we gonna have for lunch today? Because I find even the simplest decisions baffling!" [Gumball giggles, and runs outside] "Look at that beautiful pigeon pecking the mold off that old chicken leg! Isn't the circle of life beautiful?!" See my point?
Darwin: Huh, well, at least I'm not like this! [Darwin "imitates" Gumball, and starts to act in a goofy manner. He starts to speak in a deep voice] "Duh! Hey, I'm Gumball! Duh! I'm too busy to look where I'm going, 'cause I'm in love with Penny or something!" [Sarah passes by, and Darwin splatters her lunch all over her] "Duh, hey Sussie! While conveniently ignoring my own character flaws, I'm happy to point out that you eat with the grace of a one-toothed camel!"
Sussie: [Sussie whimpers sadly]
Darwin: "Hey Rocky! Let me help you with lasagna!" "Zoom! Zoom! Zoom!" [Darwin pushes Rocky out of the way, and starts throwing lasagna all over the room, hitting a few students in the process, including Leslie, Carmen, and Juke] "What the what?! I should apologize, but I won't because I always assume I'm in the right! Duh!" [Darwin starts acting normal again] You see my point?
Gumball: It would be hard not to. Okay, you're the boss now. You get that game back from Tobias.
Darwin: [Darwin gasps] Finally! I've been waiting for this for so long! So, what should I do?
Gumball: I don't know. I'd do something dumb and petty, like take something he likes, and not give that back.
[We cut to the Watterson residence]
Gumball: YOU STOLE HIS MOM?!
[We cut to Gumball and Darwin's bedroom. It seems that Darwin kidnapped Jackie Wilson, tied her up in a chair, put headphones on her head so she won't be able to hear, and gagged her]
Darwin: What? You said to take something he likes!
Gumball: Something, not someone! Have you gone totally nuts?!
Darwin: Uhh...Did I go too far?
Gumball: Oh, I don't know. Why don't you ask our new house guest?! Do you think he's gone too far? Oh, right. She can't answer, BECAUSE YOU TIED HER UP, YOU PSYCHO!
Darwin: Look, it's not that bad. Tobias will know where she is as soon as he gets home and reads the note I left.
Gumball: Okay, you know what? I'm out.
Darwin: Uh...The thing is, I kinda signed the note from both us, with you being my sidekick and all...
Gumball: Uh... [Gumball quietly sighs angrily] We're taking this poor mom back home before anyone notices she's missing.
Darwin: Hey! I'm the one in charge! We do what I say, and I say we do what you just said!
[We cut to outside. Gumball and Darwin are struggling wheeling Jackie back to her home]
Gumball: I can't believe this! Do you realize that this is a living, breathing mom that you stole? Poor thing! Oh...We should take the back-road so that we won't be seen by anyone.
Darwin: Wait. Since when does the sidekick give the orders?
Gumball: Since the leader turned into a momnapper!
Darwin: Oh, so I make one little mistake during my first day on the job, and you decide I'm a criminal!
Gumball: I didn't decide that! Society did! Now, I'm making an executive decision and taking charge!
Darwin: You don't have the authority!
[Jackie slowly wheels down the sidewalk, and she speeds up gradually saying something but is muffled. Gumball and Darwin don't notice]
Gumball: That's it! I am taking your leader badge away! [Gumball "takes" Darwin's "leader badge."]
Darwin: You never gave me a badge!
Gumball: It's an invisible badge!
[Darwin draws an invisible sword]
Darwin: You better give that back!
Gumball: What's that?
Darwin: It's my invisible sword. Don't think I won't invisibly use it!
Gumball: Well, try getting past my invisible bazooka!
[Jackie slides down the sidewalk, faster, and faster. She can be heard mumbling and screaming]
Darwin: Well, I'm coming for you in my invisible tank!
Gumball: Invisible army, fire!
Darwin: Don't make me use my invisible nuke!
Gumball: No! [inaudible] You'll wipe us both out!
Darwin: Okay okay. Truce. Let's just work together. Wait a minute...
[Jackie is seen sliding down the sidewalk again, screaming profusely. There are tons of cars passing by on the road, and she's getting pretty close to it. Gumball and Darwin run to the rescue!]
Darwin: Aw, man! She's going to get creamed, and it's all my fault! I never should have done this!
Gumball: You're just realizing that now?
[A huge track is on the road. Jackie is approaching it. Gumball grabs a nearby rock, and he throws it on a switch underneath the chair, causing the chair to lower Jackie. She passes underneath the truck without a scratch, gets lifted in the air, and safely lands in a bush]
Gumball: [Gumball sighs] Okay, that didn't work. Let's take the shortcut through Main Street!
Darwin: But, there's hundreds of people! We'd have to be invisible!
Gumball: I've got an idea.
[Gumball and Darwin draw a "face" on Jackie's blind fold, and her duct-taped mouth. They pass through the street, acting as if they are beggars]
Gumball: People, please give generously to the cause of this poor woman! Open your wallets as wide as your hearts! It's for a good cause!
Darwin: I feel so conflicted. I'm glad this is working, but I'm really disappointed in mankind right now.
Mister Small: Hold on! I've got change for you!
Gumball: Just ignore him and walk faster. Come on people! Don't be greedy, give to the needy!
