The world is in black and white as the episode begins. Gumball and Darwin, devastated, crash through the ground. It then shows them, in reality, with their parents and Anais watching them writhe on the floor. Anais states that Mr. Robinson moving is not the end of the world. Nicole suggests that they might have pleasant neighbors this time. Gumball and Darwin become semi-demonic and rebuke their mother, making her take her words back- literally. The two then worship a shrine dedicated to Mr. Robinson and Darwin breaks a vow of silence, causing them to cry even more. Nicole then shows them that he is still there. She takes them outside and they look at Mr. Robinson- who inadvertently moons them. Gumball hurriedly tells Darwin they should be with Mr. Robinson, creating precious memories.
Mr. Robinson complains as he walks down a ladder because of a heavy weight on his back. It is then revealed that Gumball and Darwin are the heavy weight, wanting to spend more time with Mr. Robinson and create more memories. The latter starts to ponder a word to describe the two, starting with hate, then despise, then abhor and finally hate again. He explains that the main reason he is moving is because of Gumball and Darwin. Gumball and Darwin then proceed to take pictures with Mr Robinson. They then ask if it would be okay to take a piece of thread from his shirt, to which he obliges, but it causes him to fall apart in the process. Before they leave, they take his eyebrow. Later, Mr. Robinson gets a call from the buyers of the house. Just then, Gumball and Darwin return and get Mr. Robinson agitated, which leads to the buyer hanging up. Gumball tells Mr. Robinson they have a gift for him, and he and Darwin proceed to serenade him with a song, but it's cut short when Mr. Robinson's potential buyers, Jeff and Susan Benson, arrive.
Gumball and Darwin return to the shrine, where Darwin asks Mr. Robinson to give them a sign as to how they can make him stay. Suddenly, a beam of light luminates the painting, with a disembodied voice telling him sabotage the sale, though it is quickly revealed to be Gumball on a stepladder holding a flashlight. Regardless, the two agree to set out and prevent the Bensons from buying the house.
After Mr. Robinson introduces himself and goes inside the house, while the Bensons stand outside feeling the soil, Gumball appears across the street with two scars and a dead eye, declaring that there's evil in the house before disappearing (or, more realistically, clumsily hiding behind a trash can after a van drives by). While walking around the house, Susan notices Darwin's shadow down the hall, but everytime she turns the light on, it disappears. Already on the edge, she is startled by walking into Mr. Robinson, who attempts to show her the bathroom, where Darwin is hiding dressed as a ghost. Susan declines, and Mr. Robinson closes the door right as Darwin is about to charge out, launching him out of the window.
Mr. Robinson then attempts to assuage Jeff's concerns about the neighborhood's safety, but is interrupted by Gumball and Darwin dressed as a criminal and police officer respecively, with Darwin aggressively handling Gumball and making Susan admit to being more afraid of the police than the criminal.
After a series of failed attempts, Gumbalf decides that the two need to go harder on the Bensons. First, once the Bensons open the Robinsons' window, they play a piano sound effect replicating heavy traffic, an airport, and a zoo. Darwin accidentally plays a sample of Muzak, confusing the Bensons, but they then play fart noises, making them think that there are vegetarians close by. In addition, Gumball and Darwin paint a hole into the underworld on the street, put radioactive waste in the Robinsons' cupboard, scare them under the bed, put a hobo in the bathtub, unleash flies onto their frontyard, and lastly, send Richard out to pound on the shed door under the impression that Anais is trapped while wearing a werewolf mask. Regardless, all of their tactics fail due to the Bensons being drawn to the quality of soil in the yard, which Gumball misinterprets as oil, believing the Bensons to be duping Mr. Robinson out of a fortune.
Hurriedly, Gumball jumps in front of Mr. Robinson's sales contract for the house just as Jeff writes his signature. Gumball, after arguing with the Bensons, drives a shovel into the ground, causing brown liquid to gush out. The Robinsons proceed to celebrate their newfound wealth and call off the sale. The Bensons walk off infuriated, with the soil now ruined by what is revealed to actually be raw sewage. They drive off as everybody else celebrates, oblivious to what really just happened, ending the episode.
[The episode starts with Gumball and Darwin falling through the house floor. Then cut to a shot of them in reality; they are imagining they are falling]
Anais: Come on, guys. Mr. Robinson selling his house is not the end of the world.
Nicole: Maybe we'll get some pleasant neighbors this time.
[Still imagining they are falling through a hole, Gumball and Darwin notice what Nicole said and fly up to the top of the hole. In reality, they suddenly get up and make angry faces]
Darwin: [Deep voice] TAKE THAT BACK!
Gumball: [Same deep voice as Darwin's] NO NEIGHBOR COULD EVER REPLACE THE MIRACLE THAT IS GAYLORD ROBINSON! TAKE IT BACK!
Nicole: OK, OK, OK. I take it back.
Darwin: DO IT PROPERLY! TAKE YOUR WORDS BACK!
[Nicole speaks in reverse]
Gumball: [Normal voice] Thank you.
[Gumball and Darwin faint and imagine they are falling through a hole again]
Anais: But hold on. If you've only just found out he's leaving, how'd you make that shrine so quickly? [Cut to a shot of the shrine]
Gumball: That? Oh, we've had that forever. Now if you'll excuse us, we have some mourning to do.
[Gumball rips his shirt off and starts mourning, with Darwin joining him silently]
Gumball: WHY?! WE HAD SO MUCH MORE TO GIVE! [Starts slapping himself in the head; Darwin does this as well] AUGH, TAKE ME INSTEAD!!!
[Darwin is still slapping his head]
Gumball: What's that about?
Darwin: [Speaks in sign language; a caption on the screen says "I've taken a vow not to speak"]
Gumball: Oh, now I understand... That I definitely don't speak sign language.
Darwin: [Sighs] I've taken a vow of silence.
Gumball: Well, you just broke it! You dishonored Mr. Robinson's memory!
[The two keep on mourning]
Gumball and Darwin: I'M SORRY!!! I'M SORRY!!!
Nicole: You guys realize he's still alive?
Gumball: You're right. He is still alive. In here. [Points to his heart]
Nicole: [Drags the boys outside] No, he's here.[Points to Mr. Robinson's house. Mr. Robinson is on a ladder, hammering a nail on the house, pants low enough to show his rear end]
Nicole: Mooning us.
Gumball: [He and Darwin gasp] We're wasting time! We should be up there, creating precious moments with him!
[Cut to a shot of Mr. Robinson from a window in the house . He is climbing down the ladder]
Gaylord Robinson: I must be getting old. This is much harder than it used to be.
[Cut to a shot of the outside of the house, where it turns out Gumball and Darwin are hugging him from his back]
Gaylord Robinson: [Notices Gumball and Darwin] What the- [Falls down the ladder] What are you doing?
Gumball: Making memories.
Darwin: We're never gonna see you again! We've gotta make every moment count!
Gaylord Robinson: Ugh... I don't have time for this.
Gaylord Robinson: Because I need to make the house perfect before the buyers see it. And also because I hate you! No, uh, "hate" isn't quite the right word, it's more like "despise". No, no, maybe "abhor". Yeah. I abhor you! No, you know what? I was right the first time. I hate you! You're the main reason I'm moving!
Gumball: I understand. You're pushing us away so you don't have to confront the pain of leaving.
Gaylord Robinson: [Squishes Gumball's face by pushing it in an attempt to push him away] No, I'm pushing you away because I like pushing you away!
Gumball: Let's remember the good times, and maybe make a few more.
[Both take selfies in front of Mr. Robinson]
Gaylord Robinson: What are you doing? I didn't give you permission to take photographs!
[Gumball and Darwin fall]
Gumball: But we've got nothing to remember you by.
Darwin: Not even a lock of your hair.
Gaylord Robinson: I'm bald! I'm not gonna give you my eyebrow!
Gumball: How about we just take this thread?
Gaylord Robinson: What are you gonna do with it?
Gumball: Take it home, cook it and eat it so you'll be a part of us forever.
Gaylord Robinson: You'll go home?!
Gaylord Robinson: Then it's all yours!
[Gumball pulls thread then Mr. Robinson's nose and face get's pulled with it]
Gaylord Robinson: Are you done here?
[Mr. Robinson's face comes back to normal]
Gaylord Robinson: Just go!
[Gumball and Darwin leave while carrying the thread like a king and singing with glory]
[Mr. Robinson's arm then falls off]
Gaylord Robinson: Oh no!
[Mr. Robinson's body then falls apart]
[Gumball takes Mr. Robinson's eyebrow then Gumball and Darwin left singing with glory]
Gaylord Robinson: Uggghhh!!!
[The scene flashes to Mr. Robinson blowing the leaves away]
Gaylord Robinson: Perfect!
[Mr. Robinson's phone then rings and answers it]
Gaylord Robinson: Ah! You're on your way, heh! Great! Great! Great! Great! Hahah! Ahahah! Heh!
[Mr. Robinson notices Gumball & Darwin then throws his phone down]
Gaylord Robinson: Get out of here! I don't want you damaging anything!
Jeff on the phone: Damage?! There's damage in the house?!
Gaylord Robinson: No, no, no, no! There's no damage of any kind! Heheheh!
Gumball: So, we were wondering what to do when we miss each other. Shall we choose a star that we can all watch in the same time?
Gaylord Robinson: Sure! No problem!
[Gets off the phone]
Gaylord Robinson: Would you please stop asking me stupid questions, you little blood-sucker?
Jeff on the phone: Who ya callin' a sucker?
Gaylord Robinson: WHAT! Ohh no! I didn't call you a sucker! No, there's a small leech problem in the garden! Uh, nothin' to worry about!
[Mr. Robinson is still talking on the phone]
Darwin: How about we swap shirts, so we can always remember each others' smell.
[Darwin grabs Mr. Robinson's collar then smells it]
[Mr. Robinson then throws the phone down]
Gaylord Robinson: I don't want your rancid stink in my house!
[Jeff screams angrily on the phone]
Gaylord Robinson: Ohh no, no no! Not you! I do want your smell! Yeah, yeah!
[Mr. Robinson is still talking on the phone]
[Gumball then taps him]
Gumball: Mr. Robinson? Mr. Robinson? Hey, Mr. Robinson.
Gaylord Robinson: Yes we can!
[Gumball taps him again]
Gumball: Mr. Robinson? Mr. Robinson?
[Mr. Robinson gets of the phone]
Gaylord Robinson: JUST STOP YOUR YAPPING!
[Jeff hangs up]
Gaylord Robinson: No, no, no, no, no! Uggghhh!
Gumball: Mr. Robinson?
Gaylord Robinson: What?
Gumball: Do you want your "Goodbye" present now?
Gaylord Robinson: Does your present involve you leaving?
Gumball: Kinda, I guess.
[Gumball and Darwin then leave running]
[Mr. Robinson then sighs in relief]
[Gumball and Darwin return dancing with long, white cloths]
Gaylord Robinson: What is this?!
Gumball: The songs of parting gift to you!
Darwin: Like we've seen people in movies do!
Gumball: They're not great movies, sure, that's true! But we'll see this through!
Darwin: I guess it's time for you to leave
Gumball & Darwin: But there's one thing you need to know! We'll never really let you go!
[Mr. Robinson then puts his hand on his face in nuisance]
Gumball: When you wake!
Darwin: And when you sleep!
Gumball & Darwin: Near or far, you must believe! We'll never really let you go-ohh! Hoahhh!
Gumball: Mountains high and rivers deep!

Gumball: We won't forget, you'll smile us back!
[Gumball & Darwin are still singing]
[Mr. Robinson notices the Bensons' car, then he blows Gumball & Darwin away with his leaf-blower]
Gaylord Robinson: Glad you can make it! Let me show you around!
[The scene flashes to Gumball & Darwin going back to the shrine]
Gumball: This is really happening, dude! They're here, ready to sign the papers. Then we're gonna lose Mr. Robinson forever!
Darwin: Oh, Mr. Robinson! If you can hear this, give us a sign! Tell us how we can make you stay!
[Light shines on Mr. Robinson's face on the painting]
[Gumball makes an impression of Mr. Robinson]
Gumball: Sabotage the sale! Sabotage the sale! Sabotage the sale!
[Darwin realizes it's Gumball]
Darwin: Dude, you could've just told me!
Gumball: Okay, sabotage the sale.
Darwin: Oh! Good idea!
Sabotaging the sale
[Both leave running]
Gaylord Robinson: [In a posh voice] Now that you have seen the grounds would you be so kind to follow me into the main house? [Bows down] I have no idea why I'm bowing like this or speaking like this but, er, please just ignore me... [Chuckles] Ah, I'll put some coffee on, you take your time.
Gumball: [Talking in evil voice] There's evil in that house...
[Closeup on Gumball's scarred face in which one eye is blinded]
Gumball: [Still talking in evil voice] I said there's evil in that house...
[Gumball snorts and spits out, only the spit sticks to his tongue and tries numerous times to get it off. Eventually, he sucks it back in]
Gumball: This is as far as I'm willing to take you, you're on your own now...
Susan: You didn't take us anywhere.
Gumball: You're on your own now!
Jeff: You didn't- ok, thank you.
Gumball: You're on your own.
[A van passes by and Gumball quickly hides behind a trashcan]
[The Bensons turn around and move into the house]
[The scene cuts to Susan going up the stairway into a dark hallway]
[Susan is about to turn the light on]
Susan: [Looks at the other section and sees a strange figure (Darwin.)][Gasps]
[Susan turns the light on, the figure then disappears. She repeats this a couple of times until she heads forward, scared]
[The figure (Darwin) quickly follows her]
[Susan is scared, and then looks behind and gasps with nobody there behind her]
[Susan walks as she looks at her back and eventually turns her head around, Running into Mr. Robinson]
Susan: [Screams, Then stops]
Gaylord Robinson: Would you like to check out the bathroom? [Opens the door]
[Darwin is seen in the bathroom, floating and colored in white, With big hair]
Susan: Maybe later...
[Mr. Robinson closes the door, Darwin then screams and gets knocked out of the window]
Gaylord Robinson: This is my wife Margaret, oh, don't worry, she doesn't come with the house.
Jeff: How safe is the neighborhood?
Gaylord Robinson: We never had any problems. I would say it's pretty s-
Darwin: Put your hands where I can see them. You're going down.
Gumball: Damned guard, I'll be out in thirty days to continue my crime spree, starting right here.
Darwin: Not on my watch, now get down on the ground! [Throws Gumball on the ground] Sir, get up, sir. You have the right to remain silent, now watch your head [Takes Gumball to the car]. Hey, this is not your car. I'll charge you with grand theft auto.
Susan: Wow, I think the police is scarier than the criminals.
Gaylord Robinson: Let's take a look upstairs.
Darwin: I am the law!
[The scene cuts to Gumball and Darwin in their room, Both with a frown as Gumball tries to hide the bump from his face till he finally hides it]
Darwin: [Takes off his hat] Sorry, dude, but with the badge, the uniform and the nun chucks' sense of authority I got a little carried away.
Gumball: That's not what I'm worried about, it's these buyers are not giving up. We need to get harder on them.
[Gumball hits his hand with a fist as the bump comes back]
[The Bensons open a window of the house]
[The sounds of a freeway are heard]
Susan: Is there a freeway nearby?
[Airplane lifting sounds are heard]
Jeff: And an airport?
[Animal sounds can be heard]
Susan: And a zoo?
[It is revealed that Gumball and Darwin are using piano sounds to sound like there are noisy things nearby, Darwin then presses another key on the piano]
[Normal music plays]
Jeff: And what can only be a giant elevator?
[Darwin plays fart sounds on the piano]
Susan: [Scared] And vegetarians!
Gumball & Darwin: Yes! [High Five]
Susan: Wow, a gate to the Underworld. Didn't notice that when we came in.
Gumball: Now, the seal of the deal. DAD, QUICK, ANAIS IS TRAPPED IN THE SHED AND WE CAN'T FIND THE KEYS.
Richard: I'm coming, baby! I'm coming for you! Daddy's coming!
Jeff: Meh, I can live with that.
Gumball: Oh, what is wrong with these people? I mean: who would wanna live in a place like this?
Susan: So, what do you think?
Jeff: Well, their house is awful and the neighborhood is like a demilitarized zone, but there's soil! That's the reason we should take it.
Gumball: There is oil under the garden!
Darwin: Mr. Robinson is sitting on a fortune and he doesn't even know.
Gumball: But those guys are not even vegetables. We gotta stop the sale.
Gaylord Robinson: So, what do you say?
Jeff: We'll take it.
Gaylord Robinson: WHAT ARE YOU DOING?
Gumball: Mr. Robinson, there's something you need to know. Mr. and Mrs. Benson are not exactly what they seem and I'm here to unmask them. [Rips a piece of Jeff's face] Ok, so maybe they are vegetables, but are here to take advantage of you.
Gaylord Robinson: What do you mean?
Gumball: They don't care about the house, they only care about what's underneath it. I let them tell you why.
Susan: Because we need good soil to plant our children?
Gumball: LIES! They only want what's under the soil: oil.
Susan: That makes no sense.
Gumball: Or does it?
[Pokes a shovel into the ground]
Gaylord Robinson: Oil?! We're rich! No sale, Margaret we're staying right here. [Everyone starts cheering]
Susan: Oh, forget it.
Jeff: Are you sure, Susan? We can always make higher offer. The soil was perfect.
Susan: No way, the neighbours are unbearable. Anyway, who'd want it? It's covered in raw sewage.
[The camera goes down and a pipe saying "Elmore City Sewage" is revealed]
