Rachel is throwing a party for her friends, and Tobias blackmails her into allowing all of his friends to come as well, though she tells them they each have to bring a date. The gang rushes off to find dates, leaving Darwin looking confused and asking what a date is. Miss Simian overhears all of this and decides to tell Principal Brown.
At lunch, Gumball suggests he and Darwin make a list of dates so they can get into the party. Darwin still doesn't know what a date is, so he asks. Bobert appears and defines it for him and quickly leaves. Darwin suggests Penny, but Gumball, being too shy, sheepishly says no. With that out of the way, the two of them begin listing girls. First is Carrie, who tries to eat a sandwich, but fails when it falls through her body. Gumball lists her as "maybe." Next is Teri, who is laughing with a few other girls. Gumball lists her as "possibly." Third is Carmen, who is reading a book. Gumball comments that she is "interesting", and moves on to Sussie, who is grossly chewing food. Gumball flatly says "no" and crosses her off the list. Suddenly, a paper airplane lands in Gumball's food. Gumball unfolds the paper and finds a note that reads "Would you be the jelly in my peanut butter sandwich?" Taking this literally instead of figuratively, he declines, crumpling the note and tossing it away. Gumball then rushes off to ask some girls out.
The scene transitions to the lockers, where Masami and Teri are chatting. Gumball goes to Masami first but angers her by calling her unattractive and doubting her femininity. She turns gray (like a rain cloud), zaps him, then storms off. Gumball asks Teri next, but Gumball messes it up by telling her she looks desperate. Teri slaps him, but since she is made of paper, it doesn't do much. Then Sussie walks by, so Gumball asks her. She responds with a stinky burp, which leaves Gumball petrified as she walks away. Banana Joe, along with his date Carmen, walks past and jokes at his failure to get a date, leaving Gumball looking hurt. Gumball is persuaded to ask Tina by Anais, and at the doorstep of Rachel's house he meets Penny, who is upset that Gumball didn't ask her as his date.
The four go inside the house, and it ends up being pretty boring for Gumball while Darwin has the time of his life. Tina asks Gumball for a dance, which he rejects. Suddenly, Miss Simian bursts through the door, spooking the party-goers, and "busts them wide open." It is discovered that her intent was not to rat the party-goers out, but to join the party. She presses a button on Juke, causing dance music to come on. The party instantly becomes exciting.
Everybody goes insane, with the TV throwing itself out the window and Banana Joe flying through a different window. Rachel is horrified, thinking that her party is ruined since only underclassmen came (trashing the house) and her friends did not. Darwin tells her that the party is not ruined since the underclassmen are her friends and he will personally clean up the entire house. Rachel doubts him for a moment, but when Darwin reassures her, she feels better about the party.
The next scene is after the crazy part of the party when most of them are tired but Sussie (in which still eating as usual). Meanwhile, Gumball had been dancing with Tina awkwardly. Penny comes up to him, dancing with Hector just as awkwardly. Penny tells Gumball that she had been the one who sent the note, which Gumball is confused about, as he states that he was not hungry and did not wish to be in a sandwich. Penny laughs, as she is amazed that Gumball did not understand the note. Then Hector offered Tina the next dance, but Tina said he can have the current dance and "drops" Gumball.
Darwin had been cleaning up the house as promised. Rachel is very grateful and asks Darwin why he doesn't have a girlfriend. When Darwin states that he does not see the point of one, Rachel shows him and kisses him on the cheek, causing him to faint. Gumball and Penny forgive each other, and Gumball asks Penny out to the next party there is (nervously). She accepts, and are about to kiss when Richard loudly honks his car multiple times, interrupting them once more. Gumball has to drag him to the car while Penny and Rachel discuss the boys that they have met (Rachel being slightly disappointed, Penny being proud).
In the car, Richard asks the boys about the party, which the boys are both very happy about; Also Richard says that he likes Penny better than Tina, making Gumball blush in embarrassment.
Darwin deciding to yodel to describe how his night went. The three drive home after a long night, just as Rachel and Tobias' parents get home and pass by Miss Simian and Principal Brown in a closet. They had been about to kiss before they had been interrupted by the parents walking by.
However, they are not fully seen, appearing only as shadows.
This is the second time the Sun talks. The first time was in "The End."
This is the first time Penny has ever been mad at Gumball. Even then, she was definitely more upset with Tina.
This is the second time Gumball and Penny have almost kissed but failed. They are also in the same outer space background, which was first seen in "The Pressure."
The imaginary bread from Gumball’s thought resembles Anton.
On Elmore Stream-It, Tina was looking for a date for a party. She could be talking about this party since she had no date when Gumball called her.
When Tobias and the gang say "Rachel, Rachel, Rachel," it is a reference to The Brady Bunch quote "Marcia, Marcia, Marcia."
Alan appeared to be shaking his face back and forth in between two balloons, a reference to the lewd act of motorboating (burying your face into a woman's breasts, then shaking it around while yelling).
When the party turns up Anton's make-up is similar to the kind that Gene Simmons - leader of KISS - has during his performances.
In the closed captions, Sussie's name is spelled Saucy.
At the beginning, despite almost all of the major students being invited to the party, in scenes set at the party, not all of them are there .
When Gumball and Penny are embracing, Penny had no arms.
Rachel said everyone had to have a date for the party; however, Darwin was at the party even though he didn't have a date.
In a forward shot of the Wattersons' car, Tina is not present.
Darwin doesn't seem to know what a date was in this episode, but in "The Pressure," he does when he tells Gumball that he needed a date to get into the tree house. This episode could have taken place before then, or Darwin might have just forgotten what a date was.
In this episode, Carmen is dating Banana Joe, but in the show's original promos, she is dating Alan. Considering this episode was written in 2009, and they were never seen dating in the show proper until Season 2, it's possible that their relationship was thought up late in production.
When Gumball is in the school hallway Gumball tells Sussie that she is his date for the party even though he crossed her off the list in the cafeteria.
Gumball was said to have asked every girl in his class to be his date, but he was never seen asking Molly or Jamie, even though they were at the party.
The characters reference the party as a "High School Party"; however, the students attend Elmore Junior High.
[The episode starts at the Elmore Junior High School, with the students crowded around Tobias]
Tina: Am I invited?
Leslie: Am I invited?
Gumball: Am I invited?
Darwin: Am I invited?
Tobias: Guys, guys! Let me cut to the chase here, alright? You're ALL invited!
Students: Yay! A high school party, and we are all invited!
Rachel: [Yells at the students] NONE OF YOU ARE INVITED!
Tobias: [Indifferent] Oh. Hi, Rachel.
Rachel: My party is for young adults, not old... BABIES!
Tobias: [Tuts and wags his finger] Rachel, Rachel, Rachel. Wouldn't it be a shame if Mom and Dad found out about your secret party?
Students: [Simultaneously tut and wag their fingers] Rachel, Rachel, Rachel.
Rachel: [Pretends to think for a second] Fine. You can come. [Some students quietly cheer] But you all have to bring... A DATE!
Students: A date?!
Rachel: Uh huh. [Walks off] Good luck!
[The students look at the camera, all in horror, apart from Darwin who is confused. Then, everyone but Darwin runs off screaming. Darwin eyes the rest, then looks back bewildered]
Darwin: What's a date? [Walks in the direction of where the rest ran off, and calls them] Hey! What's a date?
Lucy Simian: Hmmm... A secret house party, eh? I'd better tell Principal Brown.
Gumball: All right, buddy, let's make a list of possible dates.
Darwin: What's a date?
Bobert: [Rises] Date, D-A-T-E, social activity undertaken by two people in suitability for a relationship. [Lowers, then rises again and tells Darwin about another meaning of "date"] It is also a fruit that makes you poop.
Gumball: Yeah... thanks??
Darwin: Hey! What about Penny?
Gumball: Penny? [Looks at her] Oh, no, no, no, I just like her as a friend... [His pupils are shaped like hearts]
Darwin: Why are your eyes shaped like hearts?
Darwin: Oh. Well, what about Carrie?
[Carrie is shown eating a sandwich]
Gumball: Carrie... She's got spirit... [A piece of sandwich falls off Carrie's body onto the floor of the cafeteria, Carrie is shocked] I'll put her in the "maybes". Next... [Teri is shown laughing] Teri... Nicely drawn features... [Teri turns her face to the right, making herself nearly invisible] But a little flat. I'll put her in the "possibles". [Carmen is shown reading a science book] Carmen... Prickly, but smart. Interesting. [Sussie is shown chewing with her mouth open with the other girls looking at her unenthusiastically] Umm, Sussie... No.
[A paper plane appears and lands in the jelly]
Darwin: What's that?
Gumball: [Opens the paper plane and there's a question written on it] "Would you be the jelly in my peanut butter sandwich?" [Imagines two slices of bread with peanut butter but without jelly]
Imaginary Bread: What do you say, Gumball?
Gumball: Nah. No, thanks. I already ate. [Crumples and throws away the paper plane] All right buddy, it's date-time!
The School Hallway
Gumball: Hi, Masami, wanna be my date? You're not really my type since I usually like attractive girls, but hey, beggars can't be choosers. [Masami gets angry and turns black] You are a girl, right? [Masami is still angry] What? [Masami strikes Gumball with lightning and flies away. Gumball screams and coughs] How about you, Teri? You look desperate. [Teri gasps, insulted, and swings her hand in front of Gumball, touching his face lightly] Was that a slap?
Teri: Yes. [Walks away]
Gumball: Uh, ouch? [Sussie walks by] Hey, Sussie, it's your lucky day, you're my date for the party. What do you say? [Sussie burps in Gumball's face and he gasps for air]
[Banana Joe and Carmen pass by while holding hands]
Banana Joe: [Laughs at Gumball] Date fail! Come on, Prickles, let's roll!
At the Wattersons'
Richard: Oh cheer up, Gumball. When I was your age, I needed a girl for a party and what I said to her was- [Stuffs a lump of food into his mouth, then mumbles before swallowing the food] And twenty years later, we're still married.
Gumball: Aww, dad, you make it sound so easy...
Anais: Are you sure you've asked every girl in class?
Darwin: You didn't ask Penny.
Gumball: Penny? She's too hot. Not- not hot, not hot... My type, not my type. [Worried smile]
[Scene cuts to a painting of Penny in Gumball's plate]
Anais: Well, if it's not Penny, there's still one girl you haven't asked.
Gumball: Really? Who? [Anais stares a him] Oh! Her-- [Anais gives Gumball the phone and he talks on it] Hi, this is Gumball Watterson calling, would you be my date to the party? Uh no, you weren't exactly the first girl I asked but... NO, NO, no, no, no, no, don't hang up! [Whispers] Please, I can beg. [kneels down] Yes, I'm on my knees. HEY, I'm not saying that! NO, NO, no, no, no, no, please don't hang up! [sighs] Fine, I, Gumball Watterson, have a stupid face... [Darwin peeks] Stuck on a big stupid head... [Anais peeks] With a tiny stupid brain... [Nicole peeks] And stupid is my favorite color. [Richard peeks]
[Darwin, Anais, Nicole and Richard laugh softly]
Gumball: [Gasp] You will? Oh, thank you, thank you, thank you so much! I'll pick you up at eight. [Hangs up the phone and looks behind him]
[Darwin, Anais, Nicole and Richard run back into their seat, while Darwin fails for a split second then flips back up to his seat.]
Gumball: Yes! See Darwin, no girl can resist me.
In the Car
Richard: [Crying] I'm so proud of you. My baby boy is becoming a man.
Gumball : Yeah! Keep it together, dad.
Richard: It seems like only yesterday we were watching "Daisy The Donkey" together.
Gumball: Dad, that was yesterday.
Richard: Well, it feels like a long time ago. And look at you now, dating a girl! [Camera zooms out, revealing Tina on the back seat, sticking out her tongue]
[Gumball rings the doorbell, waiting with Darwin and Tina, then Penny and Hector appear]
Gumball: Hi, Penny!
Penny: [Disappointed] Yeah, Hi, Gumball.
Gumball: So... I didn't realize you were coming with Hector.
Penny: I didn't realize you liked lizard-breath. [Tina is smelling her breath]
[There's an awkward silence]
Darwin: I feel awkward.
Nigel Brown: [Pops out of the bush] Ahh... More guests have arrived. Shall we make our move?
Lucy Simian: [Pops out of the bush] Patience, Nigel. Let's wait until it's in full swing. [Both hide back into the bush]
Rachel: [Opens the door, feeling excited, then becomes disappointed] TOBIAS! More of your dweeb loser baby friends have arrived. [Walks back into her room]
Tobias: GUYS! GUYS! This party is totally off the hook!
[Gumball and Darwin walk into the house and they are shocked. Bobert, Anton and Banana Joe are dancing while clapping their hands]
Teri: [Pours tea into two cups] Any room for more tea? [Pours tea into Leslie's pot]
Leslie: Don't mind if I do.
[Molly and Rob are playing catch using Alan as the ball]
Alan: Whoohoo! This is such fun!
[Sussie is eating potato chips with her mouth open]
Gumball: [Unimpressed] This is a high school party?
Darwin: I know... It's AWESOME! [Runs excitedly] Woohoo!
Tina: Wanna dance?
Gumball: Ugh, you go ahead. I'll join you later.
[Darwin is playing leapfrog with Idaho]
Clayton: I'm having the time of my life.
Miss Simian Crashes the Party
[Miss Simian busts down the door]
Lucy Simian: This party is busted! [Some of the students are putting their hands up] Busted WIDE OPEN!
Nigel Brown: Busted...
Lucy Simian: Now for some real music! [Changes the music by using Juke, and a rock music is playing louder]
[Everyone screams, violently smashes things, and makes horn gesture. Alan attempts to fit himself into balloons, Leslie is dancing with his pot on his head, Rob is switching the lamp shades on and off with Tobias (with the shades on their heads) and Sussie is still eating chips]
Jamie: Hey, look! I'm gonna throw the TV out of the window.
TV: Please, allow me. [Jumps out of the window]
Rachel: NO! Not the TV!!!
[Miss Simian slams Rachel, the crowd throw Miss Simian into the air, then Miss Simian falls onto the floor]
Nigel Brown: That's my girl! WOOHOO! [Bumps his head with Bobert]
[Molly and Carmen jump on the sofa, Molly jumps so high and pops out of the roof]
Sun: [Angrily] Hey, dude. I'm trying to sleep here!
[Rachel is seen sitting on the stairs outside and crying]
Darwin: Hello. [Walks out toward Rachel] Hey, why are you crying?
Rachel: [Sadly] Because this is the worst party ever! I invited everybody and none of my friends turned up!
Darwin: But we all came and we're your friends!
Rachel: You guys aren't my friends. YOU JUST TRASHED MY PARENTS' HOUSE!
[Banana Joe flies out the door and laughs, then enters the house]
Darwin: Don't worry, I'll tidy it up!
Rachel: Yeah, sure, you're gonna tidy all this up?
Darwin: Of course! Don't you know I'm part sucker fish?! [Makes a sucking noise]
Rachel: Thanks. [Sniffs] What's your name?
Darwin: Darwin Raglan Caspian Ahab Poseidon Nicodemus Watterson III.
Rachel: [Giggles] You don't seem so bad, for a kid.
[Scene changes back to the party, with everyone down. Teri is asleep on the floor with drawings on her, Juke is sleeping in a corner, Sussie is still eating, and Idaho and Banana Joe are dancing slowly with parts of their skin peeled off]
Idaho: Haha! I'm doing the mashed potato!
Leslie: [Lies facing down on the ground, then raises his head, revealing his wrinkled face] Ahh... Thirsty!
[Penny and Hector are dancing together. Gumball and Tina are also dancing unenthusiastically]
Penny: Hey, how's your date?
Gumball: [Sarcastically] Grrreat. How's yours?
Penny: Hector's not really my type... Gumball? Do you remember that paper plane?
Gumball: Umm, oh yeah! "Will you be the jelly in my peanut butter sandwich?" I wasn't really hungry.
Penny: No, silly! I was the peanut butter.
Gumball: What?! Oh, I was supposed to be the jelly, wasn't I?
Penny: You seriously didn't understand?
Gumball: Uh, no.
Hector: Hey, Tina! Can I have the next dance?
Tina: You can have this one. [Drops Gumball]
After the Party
[Darwin sucks the messes like a vacuum cleaner, sucks the damaged sofa and spits it, turning it into as if the sofa was new]
Rachel: Darwin! You're the best kid ever! How come you don't have a girlfriend?
Darwin: What do I need a girlfriend for?
Rachel: This. [Kisses Darwin's head]
Darwin: [Whispering] Everything's so clear now. [Flips upside down with a huge smile on his face]
Rachel: Is he gonna be alright?
Gumball: Yeah, yeah, he'll be fine. Uh, Penny?
[Suddenly, the world fades away as Gumball and Penny are surrounded by the vastness of space once again.]
Gumball: Um, I was thinking about the, you know, next party? Maybe you can be the sandwich in my uh, peanut jelly butter... you know what I mean.
Penny: [Giggles] Yeah, I'd love to.
[Penny and Gumball lean in for a kiss...only to be interrupted by Richard, who honks the horn repeatedly]
Rachel: I think your dad's here.
Gumball: Oh, well. Time to go... [Sadly] I guess. [Perks up again] C'mon buddy! [Drags Darwin] Thanks for the party! I love you, Penny! [Facepalms] What did I say that for?!
Rachel: Is that really the best we can do?
Penny: I think he's awesome. [Blushes]
Back in the Car
[Darwin, Gumball, and Richard are all sitting silently in the car]
Richard: [Whispers] I like the new one better.
Gumball: [Blushes] Who? What? Penny? Oh no, I don't love her! I-I mean love her! I mean like her. Can we go home, please?
Richard: And how was the party for you, Darwin?
Darwin: I don't know exactly how to put it into words, but... [Starts yodeling]
[At Tobias' house]
Jackie: See? Didn't I tell you we could trust Rachel and Tobias while we're away?
Harold: Huh, wait 'till we see the phone bill.
[Closet door opens, revealing Principal Brown and Miss Simian, who are then shocked]
