Gumball and Darwin are at the school stadium, watching cheerleaders practice. When the cheerleaders form a pyramid, they collapse, injure themselves, and explode. Afterwards, the boys wonder whether the cheerleaders are missing something. Suddenly Mr. Small shows up, wearing a tin foil hat, and claims there is a conspiracy of things going missing in Elmore. He then advises them to "look for what is not there, look for what does not make sense."
As Darwin puts his book in his locker, he feels that something is missing. He notices there are lockers 115 and 117, but no 116. The boys conclude that someone is missing, so they refer to the school yearbook for clues. There they find pictures that show evidence of that "someone" has been erased from this world. After a bit of effort to remember, Gumball realizes the missing person is Molly.
Soon the boys ask their classmates if anyone remembers Molly, but no one else does. They then get Mr. Small (who gives them a couple of tin foil hats) to investigate Molly's disappearance further, starting with the missing locker. Mr. Small advises Gumball to look closely (both literally and figuratively) and he discovers a photograph of Molly with him and Darwin standing in front of her treehouse, tucked away in the gap where locker number 116 used to be.
Next, they set off to visit Molly's treehouse. While walking, Mr. Small discusses how Elmore is not a normal place, and how it sometimes makes mistakes. He trips, and the boys discover her treehouse, too, is missing, as well as a gap where "the world folded in on itself." They pry the gap open, and they all get sucked into the Void.
Inside, they behold every mistake the world has made, such as jorts, LaserDisc, and the mullet. Gumball and Darwin set off to find Molly, while Mr. Small searches for Janice. Inside her treehouse, they find Molly frozen in time. Gumball pokes her, and she unfreezes. She apparently does not remember being sucked into the Void, and acts as though she has seen the boys just yesterday. She wonders what happened to her, and the boys speculate it is because she is "boring." Nonetheless, the trio get out the treehouse, and are horrified to find the gap fast shrinking.
They rush toward the closing gap, and meet up with Mr. Small. He manages to find Janice—who turns out to be a van. They board the van and struggle to start the engine. Eventually, the van starts up, and they propel through the gap just in time.
Outside, they all celebrate for Molly being rescued, and both Gumball and Mr. Small exclaim that they should inform others of the Void's existence. However, the Void soon sucks in their tin foil hats, along with their memories of the Void, ending the episode.
The tinfoil hats worn in the episode are associated with conspiracy theories, due to the belief that the hats prevent mind control by governments, spies, or paranormal beings that make use of extrasensory perception.
Primarily, they heavily resemble the tinfoil hats in Signs.
The zeppelin that caught on fire is a reference to the Hindenburg disaster, where a passenger airship caught fire in exactly the same manner (the fire starting near the tail of the ship).
The frog standing in the way of Mr. Small's van resembles the Crazy Frog.
While Mr. Small searches for his van, a ventilation tube from the Titanic is seen in the background.
Gumball and Darwin using hairspray cans to fly through the Void is similar to a scene from WALL-E where the title character flies through space with a fire extinguisher.
When Gumball and Darwin run into a meditating Mr. Small, he looks like Dhalsim from the Street Fighter series.
The three objects in the Void, which are jorts, laserdiscs, and mullets, reference the three objects Regular Show seems to promote.
When Darwin gets mad at Gumball, his eyelashes go missing.
Despite the fact that all the evidence disappears, Molly's picture was visible in the yearbook.
At the end of the episode, Gumball, Darwin, Mr. Small, and Molly lose their memory of what happened. However, Molly was not wearing a tinfoil hat. It is unknown if she can remember the adventure she had with the boys or not.
Although Molly was erased from the photos she appeared in, she appeared in photos in three episodes which aired after she disappeared, and before she was rescued.

[At the Elmore Stadium, Gumball and Darwin are watching the cheerleaders practice]
Cheerleaders: Go, Elmore, Go! Go, Elmore, Go!
Gumball: Woo! Ready! Yeah! [fires air horn] Woo! Mexican wave! [Performs a Mexican wave by himself] Listen to the crowd, they love you! [Imitates spectator cheer, then angrily looks at Darwin. Darwin cheers, albeit unenthusiastically] Dude, that sounds like a cow on anesthetics.
Darwin: It's not that I'm not supportive but... they're kind of a train wreck... that like, a truck crashed into... and then the whole thing sunk into a lake... and managed to catch fire... and exploded.
Cheerleaders: Go, Elmore, Go!
[The cheerleaders fall and injure themselves]
Sarah: Ugh, my tail cone…
[Teri gets shredded by Carmen]
Darwin: Alright, I guess they didn't explode, but you have to admit that was- [Explosion]
In the Schoolyard
[The school bell rings. Gumball and Darwin are talking in the schoolyard]
Mister Small: [Pops up] You notice too? Stuff goes missing all the time in this town. Everyone pretends it doesn't happen, but I say it's a conspiracy. That's why I've got my hat on! TO STOP THEM ERASING MY MEMORY AND FORGETTING WHAT WAS TAKEN FROM ME!
Gumball: [Nervously] Oh, hehe so it's both fashionable, and useful.
Darwin: What have you lost, Mister Small?
Gumball: [Whispers] His marbles?
Mister Small: No. The love of my life, Janice.
Darwin: Mr. Small. With all due respect, how do you know that Janice didn't just leave you?
Gumball: Yeah, because of… you know… the hat, the ponytail, and the whole… [Does the coo-coo sign]
Mister Small: [Laughs insanely] Janice could never leave without me. [Chuckles]
[He walks away]
Mister Small: [Comes back suddenly] Look for what's not there, look for what doesn't make sense.
Gumball: I think we're looking at it right now.
[Mr. Small walks away again. Gumball and Darwin sigh]
Mister Small: [Comes back suddenly again]AND MAKE A HAT!!
In the Hallway
[Darwin puts a book in his locker]
Darwin: You know, I kinda feel something's missing too.
Gumball: Your fingers?
Gumball: Some kind of a torso?
Darwin: No, think about it. Something that used to be here at school, but now it's gone. [Sigh] Never mind. [Closes locker][Gasps] Look at this!
[He gestures to the locker numbers. There is 115 and 117, but-]
Darwin: There's no 116! There's a locker missing.
[He traces his fin along the line where the locker seems to have folded on itself. Both Gumball and Darwin see that the school's section aligned with the locker also folded on itself, with a door being reduced to half its size on the opposite side. The door opens, and the cheerleaders come out. They don't seem aware of this, even when Sarah's head gets lodged in the doorway]
Gumball: Okay. Even I can tell something's missing here.
Darwin: Maybe it's not something. Maybe it's some-
Darwin: No. Someone.
Gumball: Yeah, well. I was gonna say that next, so- [Blows raspberry]
Darwin: Let's look at the yearbook. [Flips pages]
Gumball: Stop! Look.
[He points to a photo of a serious Principal Brown, showing only his upper body. Under the photo, someone had drawn a skirt, and slender lady legs to match Principal Brown's upper body. Gumball snickers, but is stopped with Darwin's glare]
Gumball: I mean- STOP! Look.
[This time, he points to a photo of the cheerleaders in a pyramid formation. But one of the cheerleaders holding up the pyramid is missing]
Gumball: It' like someone was… erased.
Darwin: Okay, concentrate. It's gotta be someone we know.
Gumball: [Closes his eyes, and strains] Okay, okay.
[Gumball tries his best to remember. Darwin's voice is heard, and Gumball opens his eyes to find photos floating around in his face]
Darwin: Du du du du- Something's missing Du du du du- [Mutters] Du du du du-who can it be? Du du du du- Remember…
[Darwin continues rotating photos in from of Gumball's face]
Darwin: Du du du du-du du du du-
Gumball: Are you du-du-du-done here?
Darwin: Well what do you do when you need to remember something?
Gumball: The same thing I do when the TV loses signal. [Pounds head repeatedly] Come on you gosh darn piece of junk! This is what happens when you buy cheap knock-offs! [Realizes] It's Molly...
Back in the Schoolyard
[Many students are gathered around Gumball]
Gumball: So you're telling me that in a class full of our friends, who went to school with her your whole life, not one of you remembers Molly?
[Everyone mutters, not knowing who Molly is]
Banana Joe: Wait, did you say Molly?
Banana Joe: Nah, don't remember her.
Alan: Maybe if you gave us some more details about her, we could all try, and remember together!
Gumball: More details? More details!? WHAT KIND OF FRIENDS ARE YOU?! SHE WAS A GIRL! SHE WAS JUST A GIRL! And that girl's name was Molly! And Molly was your friend…and a girl…
Carrie: You don't remember her either, do you?
Gumball: NO! YOU'RE RIGHT! I HAVE ABSOLUTELY NO IDEA WHO SHE IS! BUT NOW THAT I HIT THIS VOLUME, I CAN'T REALLY STEER AWAY BACK DOWN. SO I'M JUST GONNA WALK AWAY [Walks away] SHOUTING. THEN I WON'T HAVE TO ADMIT…
Mr. Small's Office
[Gumball and Darwin enter]
Darwin: Mr. Small! You're not actually crazy!
[Mr. Small, almost naked except for a loin cloth, is meditating with a tin foil hat. Eyes are drawn on his torso, and the top of his head is colored yellow with a vertical red stripe.]
Gumball: Or not completely, anyway.
Darwin: Your conspiracy theory. It's true!
Mister Small: I knew it! Red heads are the descendants of an alien race.
Gumball: No, not that one. The people disappearing, remember? We need your help to find our friend, Molly.
Darwin: And your Janice.
Mister Small: Right. I foresaw that you would come to me, so I made these. [Shows two more tin foil hats, and puts them on Gumball and Darwin]
Darwin: How did you know?
Mister Small: [Gestures to torso] The six nipple-eyes see the past, the present, and the future.
Gumball: … [Whispers to Darwin] Six?
Back in the Hallway
[Mr. Small investigates the gap where the missing locker used to be]
Mister Small: Hmm…yeah, I see...
Gumball: So, what do you think?
Mister Small: Oh, You're right. The locker's gone. But there's something left here.
Gumball: Well I don't see anything.
Mister Small: Look closer.
[Gumball steps forward to gap]
Mister Small: Closer.
[Gumball steps forward to gap]
Mister Small: Closer.
[Gumball bumps into gap]
Darwin: I think that might be a little too close.
Gumball: [Muffled] Wait wait! There is something in here. [Pulls out face] Quick, Mr. Small. I need a pin!
[Mr. Small takes a pin from his head, and his head fluff puffs up. With the hairpin, Gumball pulls out a photograph]
Gumball, Darwin and Mister Small: ♪ Clue! ♪
[Darwin looks at it, and sees himself, and Gumball with Molly and her treehouse]
Darwin: [Gasps] Oh yeah! That's Molly.
Gumball: We were definitely friends!
Darwin: How could we not remember? And her treehouse.
Gumball: Yes, yes, that's it! All we have to do now is build a treehouse just like hers, and she'll come right to us!
Darwin: Or we can try, and find hers since that's probably where she is.
Gumball: Or, we could try, and find hers because that's probably where she is!
Darwin: Oh my gosh! That's a much better idea.
The Discovery of a Lifetime
[Cut to the three walking by the streets]
Gumball: Mr. Small, do you remember Molly?
Mister Small: Of course I remember her. Thanks to the hat.
Darwin: What was she like? We've completely forgotten about her.
Mister Small: Well, let's see. She was boring, and uh…ooh…eh…no, that's it. She was just boring.
Darwin: What do you think happened to her?
Mister Small: Well kids, Elmore is not a normal place.
[A yellow wig walking its dog passes by]
Dog: Oh, hello!
[A yellow wig Barks]
Mister Small: It's a pretty weird world, and sometimes it makes mistakes.
Darwin: Do you think the world thought Molly was a mistake?
Mister Small: Yeah. If I was the world, I'd be pretty bummed with coming up with someone as boring as Molly- [Trips and falls on face]
Darwin: Mr. Small! Are you okay?
Mister Small: Of course! Pain is just information that the mind can master.
Gumball: So it didn't hurt bad?
Mister Small: [Sarcastically] No, I feel great.
Darwin: [Gasps] Look! Another clue. Just like at the locker.
[The street is also folded on itself. Gumball takes out the photo from earlier, and compares it to the area]
Gumball: But her whole house is gone. It's like the world folded in on itself again.
[It is revealed that the area were Molly's house has disappeared, sky and all, is flat like a wall]
Gumball: What is this? What's going on here?
[The gap were the world folded in itself sucks in the photograph of Molly with the Wattersons]
Mister Small: The-
[Gumball's face is suck into the gap, and his head is eventually engulfed in it]
Darwin: I got you. I got you!
[Darwin pulls him out. Gumball's face is stretched]
Darwin: Oh my gosh, your face!
Gumball: If you think that's weird, you should see what's in there.
[They prepare to pull the gap apart]
Mister Small: Are you sure you wanna do this?
Darwin: We have to! We can't forget about our friends.
Mister Small: Okay. On three. Two. One!
[They pry the gap's sides apart, revealing the Void and all its contents]
Gumball: On second thought, maybe we should just forget about Molly and Janice and stuff. I don't remember Molly anyway. And if the world decided that she was a mistake, then who are we to t-
[Darwin pushes Gumball into the Void]
Mister Small: Darwin! It wasn't very nice of you to push your brother in such a way. People will allow-
Darwin: [Darwin grabs, and throws Mr. Small into the Void while he continues talking; Throws himself into the Void]
Into the Void
[The three land on a piece of floating]
Mister Small: Look, children. All the mistakes the world has ever made.
[He gestures at some floating objects]
Mister Small: Jorts, Laser Disc, The Mullet .
Darwin: [Points at treehouse] Guys! It's Molly's treehouse.
Mister Small: Okay! You get her, and I'll find Janice. Whoa! Oh yeah!
[Mr. Small hops his way around on pieces of floating land, and other objects]
Darwin: Mr. Small! Wait! [Hops]
[He lands on a rock cloud while Gumball bounces against some objects, Rob is seen]
Gumball: Oof! How come- [Hits object] you're- [Hits object] so good- [Hits object] at this- [Hits object] jumping!? [Groans]
Mister Small: Let's just say I'm used to feeling spaced out.
Gumball: Okay. How do we get to the treehouse?
Darwin: [Grabs hairspray] Let's use this highly toxic hairspray from the eighties!
[Cut to Gumball and Darwin flying through the void, using the hairspray to navigate. Darwin's spray goes behind him, to a coughing Gumball, and makes the latter's hair grow. They then climb the treehouse]
Gumball: Molly! Molly?
[Molly, in the middle of pouring her tea, is frozen in the treehouse like a statue]
