The episode begins with Gumball and Darwin trying to find a new greeting gesture and a name for it in order to look cooler. However, his suggestions prove only to be silly. Then Darwin brings up that Tobias also has a unique way of greeting; starting by giving people a high-five and then slapping them on their butts. Just then, Tobias comes and slaps Leslie, Idaho, Alan, Hector, and Darwin but Gumball is shocked and disappointed that he is excluded from the butt-slap and is merely given a high-five. Although Darwin is surprised, he claims Gumball is lucky. But Gumball is unable to let it go and attempts to get Tobias to slap him.
Gumball's attempts prove futile, however, as Tobias continues to avoid to slap him on the butt whenever he greets him. This makes Gumball even more determined and going so far as to pretend to be choking, posing as a bongo and somehow puts his butt inside a book to get a slap from him. After various backfired attempts, Gumball begins to think that the reason Tobias excludes him is because of who he is and that he is not good enough. After a musical number, Darwin suggests Gumball that he should just let this slide and that he is there to help him.
Misinterpreting Darwin's offer to help, Gumball drags Darwin to school in order to help him get Tobias to slap his butt. Once again, Gumball's attempt to do so fails. Refusing to give up, Gumball attempts to befriend Tobias. But he is unable to do that as he only succeeds in creeping him out and scares him off. Darwin explains that friendship cannot be forced and takes time through kindness. Ignoring his advice, Gumball begins planning his next and final move.
Tobias is later summoned up on the school roof after receiving a note which he assumes is from Masami. Gumball then closes and locks the door behind him and reveals his deception and asks what they should do now while panicking. Tobias claims they must do what real men do; survive. Then he proceeds to try to eat Gumball, leading Gumball to try eating Tobias as well. Realizing the stupidity of that plan, the two try working together to survive such as making rat traps for food and signaling a helicopter. All of which fails badly and they believe they are about to die soon.
Suddenly, Rocky appears in front of them and claims he and Darwin have been looking for them for days. Darwin tells Gumball the important lesson he expected him to learn from this experience. However, this only reminds Gumball of the reason why he locked him and Tobias on the roof in the first place and tries to get him to slap his butt once more. The next day, Tobias finally slaps Gumball on his butt. However, Gumball slaps him back on the cheek and angrily storms off, and Tobias facepalms, ending the episode.
While trapped on the rooftop, Gumball and Tobias lay down on top of each other in the hot sun, continuously flip each other over, and leave prints of their bodies, likely referencing the SpongeBob SquarePants episode "Home Sweet Pineapple," where SpongeBob pours green paint on the front of his body, red paint on his back, and flips his body along a picket fence, leaving prints.
When Tobias walks away from Gumball and Darwin, Juke's back can be seen in the background; the voice/music switch on the back of his head is aligned horizontally, when in "The Boombox," the switch is aligned vertically.
[Elmore Junior High schoolyard. Gumball has a finger in Darwin's mouth.]
Gumball: No? [Takes his finger out]
Darwin: No, I don't think USB-ing will replace the high-five.
Gumball: Maybe it's the name. What about..."digit-docking".
Darwin: I don't think the name's the problem. Although admittedly that name would be a problem.
Gumball: Oh, how about a more manly version of the classic French greeting? Okay, do this. [Puts his arms up as if flexing]
Gumball: [Kisses Darwin's biceps] And now you kiss my guns.
Darwin: [Looks him up and down]
Gumball: Too manly?
Darwin: [Nods] ...Yeah.
Gumball: What about the dog salute? [Barks, imitating a dog with his hand]
Darwin: Uh, maybe?
Gumball: [Sniffing noises]
Darwin: What's that?
Gumball: They're sniffing each other's backsides.
Darwin: Eh, I suppose that's still better than what Tobias does.
Gumball: What does he do?
Darwin: Starts kinda normal with a high-five but then, right after, he gives you a slap on the butt.
Gumball: [Offended] That's outrageous! Exactly the sort of unpleasant macho behavior that my new greeting will eliminate. The nerve!
Darwin: Here he comes.
[Tobias enters the schoolyard and greets his friends.]
Tobias: Hey. [High-fives Leslie and smacks the back of his pot]
Leslie: [Outraged] Oh!
Tobias: Hey Idaho, my bro-tato. [High-fives Idaho and slaps his butt]
Idaho: [Sent flying] Aah!
Tobias: Alan, my man! [High-fives and "butt"-slaps Alan]
Tobias: Hey big guy, put it right there. [High-fives Hector then climbs up his leg to slap him]
[Tobias walks up to Gumball and Darwin.]
Tobias: Hey dude, gimme some fin! [High-fives and butt-slaps Darwin] Hey man. [High-fives Gumball normally then walks away]
Darwin: What? He did it to everyone except you!
Gumball: Psh. Yeah I know, I wouldn't, like, take that, you know?
Darwin: You're lucky. You're literally the only guy he doesn't do it to.
Gumball: Yeah I know I'm- I'm lucky. Yeah. [Sad face]
Quest for the Slap
[Gumball, Darwin, Tobias and others are in gym class.]
Coach Russo: Okay, that's time, wrap it up.
[Everyone starts heading to the exit, where Tobias waits to "high-five" classmates as they leave.]
Tobias: Good game! [High-fives and butt-slaps Anton] Well played. [High-fives and butt-slaps Darwin] Catch you later-
Gumball: [Looks at Tobias eagerly]
Tobias: Uh. Good job!
[Tobias reaches out his hand to Gumball but his legs extend so that Tobias' hand is at butt level. They awkwardly shake hands. Gumball lets out a disappointed sigh and hits his head on the door frame as he walks out with his legs still extended. The school bell rings, Gumball is in the hallway peeking around a corner to spy on Leslie and Tobias.]
Tobias: I'm telling you man, Masami winked at me this morning! She went like this: [Closes both eyes slowly]
Leslie: Technically if you close both eyes it's blinking.
Tobias: Nah, double the winks, double the trouble dude! Anyway, catch you later. I gotta go wiggle my eyebrows at her. [He high-fives and slaps Leslie then walks to Gumball]
Gumball: Oh, hey man.
Tobias: Oh, uh. [They high-five] Hey.
[Gumball presents his butt to Tobias, wiggling his eyebrows and smiling at him.]
Tobias: Uh, yeah... Gotta go. [Walks away]
Gumball: [Serious tone] You will slap my butt today, Tobias Wilson, even if it's the last thing you do- [Normal voice] Wait, if it is the last thing he does today it would probably be at bedtime, which is kinda weird. Rephrase! [Rewinds] Even if it's the last thing you do...before the end of school.
[He starts running and spots Tobias.]
Gumball: [Winded] Hey, hey.
Tobias: Hey...again. [They high-five]
Tobias: Uh, see you later.
Gumball: [Squints] Aren't you forgetting something?
Tobias: No, I don't think so... See you!
[Tobias tries to walk away but Gumball's butt extends to stop him. He manages to squeeze through along the wall and runs away.]
Gumball: Oh, come on!
[Gumball's butt suddenly retracts, knocking Darwin out.]
[School bell rings. At the school cafeteria, Leslie chokes on his food. Tobias slaps his back, saving him. Witnessing the scene Gumball pretends to choke.]
Gumball: Help, help!
Tobias: [About to slap Gumball]
Gumball: Hold on. [Stops choking, bending to show his butt instead]
Hector: I got this! [His hand breaks through a window and slaps Gumball into the camera, shattering it.]
[In music class, Tobias plays the drums lined up in front of him, sees the last one is Gumball's butt and hesitates for a second before deciding to hit a crash cymbal instead. Gumball stands up, glares at him and walks off. In the next scene, Tobias tries to swat a fly with his hand. Gumball jumps in butt first, knocking the desk over and crashing into something offscreen. Finally, at the library, Tobias opens a book and Gumball's butt pops out of it.]
Darwin: Dude, what are you doing?
Gumball: [Head pops out of Darwin's book] I don't know anymore.
[When Tobias is about to slap Darwin's butt, Gumball pushes him out of the way and presents his butt instead. In slow-motion Tobias realizes who he is about to slap, he slaps his own face and knocks himself out.]
Gumball: Noo! Now he'll never slap me on the- Oh wait. It still counts if he's unconscious, right?
Darwin: [Silently shakes his head in disapproval]
Gumball: Yeah, it counts. [Grabs Tobias' limp arm] Aaand, I just realized this is wrong on so many levels.
Bonding with Tobias
[School bell rings. Gumball and Darwin are sitting in class.]
Darwin: If it means so much to you, why don't you ask Tobias directly?
Gumball: Hey! I'm not a beggar, I'm a chooser.
Darwin: Maybe he thinks you guys aren't friends enough for this kind of...contact.
Gumball: So, you're telling me I need to [Evil voice] lure this hopeless fool into the deadly web of my friendship.
Darwin: You're making it sound creepy. How about you just be nice to him?
Gumball: [Evil voice] Yes! Gain his confidence then stab him in the heart with the burning blade of my friendship.
Darwin: Yeah, that sounds even worse.
Gumball: [Evil voice] Infiltrate his tender heart, so he will lay his hand on my-
Darwin: You know what? Let's just...skip to the moment when you fail.
[School bell rings. Tobias is eating at a table in the cafeteria.]
Gumball: [Evil voice] Here, friend, have some of my dessert. Lap it up. [Shoves a spoonful of food into Tobias' mouth] Lap it up good. [Maniacal laugh]
Tobias: [Spits] Look buddy, if you don't back off I'm gonna have to get physical! [Raises his hand threateningly]
Gumball: [Evil voice] Yes! [Presenting his butt] Use your anger and fall into my trap, you worm!
Tobias: I haven't touched you and I already feel like I need to wash this hand. [Walks away]
Gumball: Oh, or we can just take it slow!
Darwin: You know, you can't just force a friendship like that. It takes time, and a lot of shared experiences.
Gumball: You're right! Nobody remembers the good times, it's the really bad times that bring people together.
Darwin: Yeah you see, you're missing the point again.
Gumball: I will put Tobias through such an emotionally scarring, physically grueling experience, that he won't slap my butt when it's over: he'll kiss it! [Runs off]
Darwin: Wait, what the- Where are you going?
[Tobias opens the door to the school's roof.]
Tobias: Masami? Are you there? [Reading a note]"Dear Tobias, meet me on the roof after school, double wink. Masami. P.S. Clips your nails." ...what?
[The door to the roof shuts. Gumball sits behind it, with ruffled fur and dark circles under his eyes.]
Gumball: [Panicking] No no no no! The door, the door!
Tobias: What are you doing here?
Gumball: What took you so long?! I put that note in your locker two days ago!
Tobias: Well, you're supposed to let girls wait. Otherwise it makes you look too desper- Wait a minute. You tricked me!
Gumball: Yes. But that's completely irrelevant now. We're trapped up here and nobody's gonna be here 'til Monday morning! What are we gonna do?!
Tobias: We'll do what real men do. SURVIVE. [Pounces on Gumball, chewing on his leg]
Gumball: [Screaming] No! What are you doing?
Tobias: We both know it's gonna happen at some point. And I'm clearly the alpha here.
Gumball: I'm the one who hasn't eaten for two days! [Starts eating Tobias] This isn't working.
Tobias: There's only one thing for it: we're gonna have to work together.
Gumball: And when you have succeeded, you can slap each other's-
Gumball & Tobias: You gotta do what you can, you gotta make a new plan,
And then you will survive
You gotta work with your buddy when the situation's cruddy
And you might just stay alive
Tobias: This seemed a good idea,
Gumball: But I think I should've stopped ya.
The end is gettin' near, what we need's- a helicopter!
[A helicopter is flying near the building.]
Gumball & Tobias: We gotta signal the guy, so he can see us from the sky,
And then we will survive
[They remove their arms and legs to form letters on the roof.]
Tobias: I got a spare leg!
Gumball: Just throw it away.
Pilot: "Need help?" No, I'm fine, thank you!
[The helicopter flies away.]
Gumball: [Angrily] What- what were you thinking?!
Tobias: [Angrily, at the same time as Gumball] Aw, this is your fault!
Gumball: [Angrily] Why would you put a question mark at the end?!
Gumball & Tobias: So we're both gonna croak from the rain or sunstroke,
Cause friendship's not enough
You can forget the bromance,
Cause we stand a better chance with actual survival stuff!
[Birds circle overhead as if about to feed on Gumball on Tobias, who are visibly dehydrated.]
Tobias: We're not gonna make it. And we're in this mess because of you! You're a...a fool!
Gumball: Yeah? Well, you look like a clown's armpit!
Tobias: [Tears up] That's hurtful because it's true. Well, your legs are so short you hover when you break wind! [Sheds a tear into his shoe and hands it to Gumball] Okay it's full!
Tobias: How does it taste?
Gumball: ...better than the other option.
Tobias: We're never gonna survive this. But before it's over at least tell me, why?
Gumball: All I wanted was one of your little butt slaps.
Tobias: But, I thought you would hate that!
Gumball: I just wanted to be included and... [Sighs] It got out of hand. And now I have to pay my taxes to this giant nostril.
Gumball: I usually file through my accountant, but he is in Boca.
Tobias: Dude, I think you're hallucinating. [Looks at Gumball, who looks like a realistically drawn cat with a human face] And your face looks like a cat, but not enough.
Gumball: [Looks at Tobias, who looks like a colorful alpaca] Yeah, you don't look too good yourself.
[Gumball and Tobias lie down.]
Gumball: I think...this is the end.
Tobias: I see...
Rocky: [Leans over Tobias]
Tobias: I see the Grim Reaper. He looks like a high school dropout chicken Kiev.
Rocky: Hey! I didn't drop out, I flaked out. Whatcha doin'? Me and Darwin have been lookin' for you guys for days.
Gumball: [Yelling] What took you so long?!
Darwin: You ran away before telling me where you were going! I think this whole experience can teach you a valuable lesson: you should never hound a friend just to get them to slap your butt.
Gumball: Darwin, thank you. Thank you...for reminding me the point of all this, I had completely forgotten! I have to get him to slap my butt!
Darwin: [Exasperated sigh]
[School bell rings. Tobias greets his friends as he walks through the hallway.]
Tobias: Hey. [High-fives and butt-slaps Juke] Hey man. [High-fives and butt-slaps Leslie] Hey G-Ball, how you doin'? [He high-fives Gumball, then gives him a smack on the butt]
Gumball: Oh! [Outraged, he slaps Tobias' face] How dare you?! You've got some nerve, young man! There are rules in this society and casually slapping people's butts is not one of them! [Storms off grumbling] Someone has to take a stand...
