The episode begins with Darwin answering the door and seeing a creature whom he dislikes at first glance. The creature wants to see Gumball. When Gumball comes, he is shocked to see that the creature is Fuzzy, his old BFF from Minnesota. Gumball tells Darwin that Fuzzy used to be his BFF, which makes Darwin jealous of Fuzzy. Darwin later puts Fuzzy in the oven along with the food, which frustrates Gumball. Darwin gives Gumball all the darns he can give about his and Fuzzy's friendship. Since Darwin ruined the food, Gumball and Fuzzy go outside to get something to eat. Darwin runs to the door trying to come up with a comeback, but he is having troubles. Meanwhile, Gumball and Fuzzy are at the playground. Gumball asks Fuzzy about his life and Fuzzy mentions Hank, his other friend. Gumball and Fuzzy are both glad to see each other again. Gumball returns home to find Darwin still trying to come up with a comeback. Darwin tells Gumball that he doesn't trust Fuzzy.
During the next day, Gumball, Darwin, and Fuzzy are playing a game together. Gumball then leaves to get some drinks, and while he is gone, Darwin jumps at Fuzzy asking him about his "game." Fuzzy asks Darwin to give him a chance, but Darwin still doesn't trust him and fears that he might do something bad to Gumball. Fuzzy leaves so he wouldn't ruin Gumball and Darwin's relationship. Gumball comes back to the room and finds out what Darwin has done. He then leaves to visit Fuzzy's home.
Gumball and Fuzzy begin walking to the latter's house, and Gumball talks about Darwin being a jerk. Since they have been walking for an hour, Gumball asks how far Fuzzy's house is. Even though Fuzzy says it's near, the duo walks for miles through a desert, a snowy mountain, and a forest. Gumball is exhausted and dehydrated, but finally, they manage to arrive.
Unbeknownst to Gumball, Fuzzy reveals his psychotic nature and forces Gumball to put on toddler clothes. He then turns on a nightlight but is hit with a shovel by Darwin. Darwin admits he's been following them because he is jealous of Fuzzy. Fuzzy wakes up so Gumball and Darwin start running away from him. Fuzzy follows them, and when Gumball and Darwin end up near a cliff, they are forced to jump. Fuzzy searches for them, but is startled when they run towards him carrying a log. They didn't manage to hit him so he picks up a rock, trying to hit them. Suddenly, Hank appears. He picks Fuzzy up and carries him away. Gumball and Darwin question whether they should help Fuzzy, but just walk home to get food from a taco truck, ending the episode.
[Right outside the Wattersons' house, the doorbell rings, and Darwin answers it]
Darwin: Uh, Gumball?
Darwin: Someone put a pair of eyes on some cotton candy and dumped it on our doorstep.
Fuzzy: My name is Fuzzy.
Darwin: Oh, no, wait. It's one of those nineties talking toys that are creepier than bald men with long hair.
Fuzzy: Dude, I'm alive. This is just how I look.
Darwin: [Gasps] I'm so sorry.
Fuzzy: It's fine.
Darwin: ...for you!
Fuzzy: Does Gumball Watterson still live here?
Darwin: Oh, yes. Gumball!
[Gumball walks over, sees Fuzzy and gasps]
Fuzzy: Hey, partner!
Gumball: Aw, Fuzzy! [Laughs] You haven't changed at all!
Darwin: Oh, so it's congenital.
Gumball: Darwin, this is Fuzzy, my BFF!
Darwin: Oh... [Chuckles nervously] Pleased to meet you.
[The scene cuts to the kitchen]
Darwin: [Grumbles] Did you really have to invite him for lunch?
Gumball: Why are you so angry I had a best friend before you?
Darwin: Heh, no one's angry. Who's angry?
[Gumball points at Fuzzy, whom Darwin is about to put in the oven]
Darwin: Oh. Sorry, dude.
Gumball: Why don't you have a seat, Fuzzy? We'll bring out some food that isn't you.
Fuzzy: Uh, thanks, man. [Exits]
Darwin: So, how long were you guys a thing?
Gumball: Uh, a few years before you arrived and before he—
Darwin: Hmm, hmm, hmm...
Gumball: Uh, what are you doing?
Darwin: Oh, I was just trying to work out if I give a darn!
Darwin: So, was it serious?
Gumball: Yeah, you know, things were moving along. We moved into a hideout together... [He notices Darwin is checking his pockets for something] Uh, what are you doing now?
Darwin: Oh, just looking for a darn to give. Were there others?
Gumball: No, of course not! You're—
Darwin: Take this. I'm afraid that's all the darns I have to give.
[Gumball groans and walks away]
Gumball: Hey dude, why don't we hang out and grab something to eat in town? The food here is a little too salty!
[Gumball slams the door]
Darwin: Oh, yeah?! Well, you know what?! Uh, you— you— you know what? Uh, uh, you— you, uh...
Gumball and Fuzzy: [Shrug] Mm-mnh. [Walk away]
Darwin: You, uh, ah...
[The scene cuts to Gumball and Fuzzy on swings]
Gumball: So, what you've been up to? How's Minnesota? Made any friends?
Fuzzy: It's hard to tell. Everyone is wearing ski masks all year long. Either I have friends or I'm on a CIA watch list.
Fuzzy: Yeah, summer's so short there they just call it "s."
Fuzzy: It's so cold up there, rappers can only sag their pants under their nipple level.
Gumball: [Laughs] Alright, alright, I get it. It's great! Stop trying to make me jealous.
Fuzzy: Yeah, well, it would've been better if you were around.
Gumball: It's that lonely up here, huh?
Fuzzy: No, I do have one friend, Hank. He's pretty frozen.
Fuzzy: That's how you say cool in Minnesota. You have to adjust the temperature. Although, if he knew I was hanging out with you now, I'd probably be in room-temperature water.
Gumball: Huh? [Gasps] Oh.
Fuzzy: He's a nice guy, but, you know, it's not the same.
Gumball: Look, I'm sorry, Fuzz. I really wanted to keep in touch and send you a letter or something, but turns out it takes toddlers four years to learn how to write. After all that time, it felt a bit like posting a get-well-soon card through the window of a hearse.
Fuzzy: [Chuckles] Well, I'm back now, and I'm glad we get to catch up on lost time.
Gumball: Me too, buddy. Me too.
Making a Deal with Darwin
[As Gumball walks back home, Darwin is still heard thinking of a comeback]
Darwin: Well, you— you know what?! Uh, well, you know what? You're like a...
Gumball: What the?
[Gumball opens the door]
Darwin: Uh, well, you know what?! Uh...
Gumball: Dude, are you seriously still looking for a comeback?
Gumball: [Laughs] Darwin, just because Fuzzy's back in my life doesn't mean I love you any less.
Darwin: Really? How much do you love me?
Gumball: Dude, I love you more than elderly people love walking around in their birthday suits in sports locker rooms.
Darwin: [Snickers] More than Canadians love telling you which famous people are Canadian?
Gumball: More than PC gamers love to bash game consoles.
Darwin: [Giggles] That's quite a lot.
Gumball: Come here.
Gumball and Darwin: [Hugging] Mm.
Darwin: I'm sorry if it looks like I'm overreacting, but I just don't trust that guy. He looks like a hairy thunb with bulbous, soulless, motion-capture eyes.
Gumball: Would you please just give him a chance? For me?
Gumball: How about we hang out together and play some games? You'll see. He's a great guy.
Darwin: Fine. [Gasps] Sorry my seasoning isn't the taste of your treasoning!
Darwin: You know, the salt comeback from before, and— oh, never mind.
[During daytime, Gumball, Darwin, and Fuzzy are playing a video game]
Gumball: Man, I am really struggling with this third-party controller. I think it's broken.
Fuzzy: Dude, that's not a controller.
Darwin: Yeah, it's the remote from Mister Dad's new massage chair.
Richard: [In the massage chair] Huh?! Uh, ugh! Ugh, ugh!
[Gumball, Darwin, and Fuzzy laugh]
Gumball: All right, you guys. Finish this one, and I'll take the winner. I'll just go get some drinks. [Exits]
Darwin: [Deep voice] Okay, what's your game, you furry creep muffin?
Fuzzy: Ugh. Look, just give me a chance.
Darwin: [Normal voice] A "chance" to abduct your best friend and lock him up in a cabin in the woods?
Fuzzy: What the? No! Look, can we just bury the hatchet?
Darwin: "Bury?" "Hatchet?"
Fuzzy: Okay, I don't know what you're trying to rope me into, but—
Fuzzy: Dude, you have a pretty weird relationship with your BFF.
Fuzzy: All right, I'm out of here.
Gumball: [Entering] What? W-why? What's going on?
Fuzzy: Look, I was gonna invite you guys to a sleepover, but I think it's best if I don't. I don't want to make any waves between you and Darwin. I just think you guys need a little chat... in front of a shrink... while wearing straitjackets... behind two-way glass... under the supervision of armed guards... because you're crazy. I just wanted to make that clear. Okay, bye. [Exits through the front door]
[Gumball enters their bedroom as Darwin is shown using the computer]
Gumball: What did you do?!
Darwin: [Scoffs] Nothing.
Gumball: You obviously did something. Did you see his face? He had the expression of someone who had just sat down on a warm toilet seat. What did he ever do to you?
Darwin: [Welling up tears] Well, when you went away to get drinks, he— he stood up, grabbed a fire poker, and... and... he... Yeah, okay, I completely made that up and probably shouldn't have.
Gumball: Agh! Why are you acting like this?
Darwin: I just think it's interesting that this guy's back in Elmore.
Gumball: No, you don't. You think it's suspicious. Just say "suspicious!"
Darwin: No, I just think it's intriguing—
Gumball: No, you don't. You think it's sinister. Just say "sinister."
Darwin: I'm just fascinate—
Gumball: You're jealous! Just say "jealous!"
[Darwin sputters, aloof of Gumball]
Gumball: Hmph. [Packs up]
Darwin: Wait. Where are you going?
Gumball: To the brony convention in Liechtenstein. Where do you think I'm going?! I'm going to Fuzzy's house. So have fun being more jelly than a peanut-butter sandwich!
Darwin: [Laughs] I'm not jealous. Look. [Holds up finger]
Gumball: What's that?
Darwin: The needle on my give-a-darn-ometer— not moving.
Gumball: Ugh. Look, you can still come if you want.
Darwin: What was that? Sorry. I just wanted to make sure I didn't look like I gave a darn.
Gumball: I said you can—
Darwin: Hello? Is this the give-a-darn store? Uh, yeah, I'd like to know if you had any more darns left in stock. Yeah, it's for a friend. Oh, you discontinued the line? I see. Oh, you might have some left in the warehouse? Sure. I'll hold. Just a sec. Ah, right. Mm.
Going to Fuzzy's House
[Gumball and Fuzzy walk through the streets outside]
Gumball: And then he was talking about how the darn mines had closed and that I should've invested in renewable darns and — whatever. Anyways, is your place very far? 'Cause we've been walking for an hour now.
Fuzzy: Oh, yeah, it's right around the corner...
Fuzzy: ...after the lake.
Gumball: Right. Um, wait, Elmore's got a lake?
[Gumball and Fuzzy are shown walking through the desert near an overpass]
Gumball: [Panting] Dude, can we at least make a pit stop? I need a new pair of feet!
Fuzzy: Oh, but we're nearly there.
Gumball: Ugh. Where?
Fuzzy: Just beyond that pass.
Gumball: The overpass?!
Fuzzy: No, that mountain pass.
[Gumball groans. They then are shown walking on a snowy mountain]
Fuzzy: Okay, maybe we need a little break.
Gumball: Oh, thank you, universe!
Fuzzy: [Sits on a log] Ah, much better. [Resumes walking]
[Gumball ends up not sitting and lets out a frozen tear. They then walk over a grassy flatland, as Gumball's eyelids are letting out a farting sound]
Fuzzy: What's that sound?
Gumball: I'm crying, but I'm so dehydrated, only air is coming out.
[In a mysterious forest in the night, Gumball and Fuzzy are still walking. Gumball collapses]
Gumball: [Rasping] I'm not gonna make it, Fuzzy. You're gonna have to continue without me.
Fuzzy: Gumball, I'm not leaving you behind.
Gumball: I never said leave me behind. I meant you're gonna do the rest off the walking, get some form of wheel-based transportation, and come back to get me. [Coughs] Also, I want a burrito.
Fuzzy: But it's just right there, right before Ontario.
Gumball: [Normal voice] Wait, are you telling me we're in Minnesota right now?
