The episode starts with Gumball and Darwin in the attic packing their old toys while preparing for the garage sale. They discover their old toys from seven years ago. Darwin sees their puppet toys, Grady, Frank, and Howdy. Gumball tells him that it is time to grow up and learn to let things go. Later, Darwin picks up Frank and Howdy and talks through them. Frank asks Darwin if they will have fun forever and ever, which Darwin promises. Then Howdy asks if Darwin will never take them off his hands again, which Darwin promises. Then Darwin goes to use the bathroom, with Frank and Howdy still on his hands. Frank and Howdy look shocked, and Darwin says they made him promise it.
Gumball and Darwin are at the bus stop, when the bus comes and picks them up. Howdy asks Rocky where he has been all of her life. Rocky responds they he has been sitting there, driving the bus, wondering what went wrong with his life. Howdy responds with "One ticket to kiss-town, please," then attempts to kiss Rocky, before he sees Darwin is behind Howdy. Due to Rocky being distracted from driving the bus, he gets into a wreck with a truck, injuring him.
In the cafeteria, Darwin walks by Rocky, and makes Howdy say "Call me" to Rocky, only making Rocky glare at it. Darwin is trying to make Howdy and Frank share a sandwich. Then Gumball comes up to Darwin, who quickly hides Frank and Howdy. Gumball talks about the school bus accident with the truck. Gumball also mocks Rocky by saying that him being a puppet driving a bus caused the accident. Frank and Howdy, who Darwin hid under the table, are offended by Gumball's words. Darwin then makes them both talk bad about Gumball. Gumball then asks Darwin what his problem is, also asking why he talked with his voice like that. Darwin responds, with his voice still talking like Frank, that his problem is that his butt is twice as wide has his shoulders, and his brain is half the size of his head. Gumball takes offense from it, and asks Darwin if he has anything else to say. Darwin says that he has nothing else to say, but also says he can try to insult his face, but nature has already done enough damage. Gumball then takes the meat out of Darwin's sandwich and slaps Darwin with the meat, then sticks the meat on Darwin's face and walks away from the table. After Gumball walks away, Darwin then takes Frank and Howdy from underneath the table.
Back at the house, Darwin is bathing with Frank and Howdy still on his hands. Frank says who skinned those puppets, referring to Darwin's socks on the bathroom floor. Darwin clears it up that those are his socks and also tells them to keep it quiet or Gumball will hear. Gumball opens the door and asks to Darwin who is he talking to. Darwin replies to him, making Gumball suspicious. Darwin pulls Frank and Howdy out of the tub. Gumball convinces Darwin to take the puppets off, but Frank and Howdy attack Gumball. After a struggle, Gumball pulls the puppets out of Darwin’s hands. Darwin pleads for Gumball to give back the puppets, but Gumball tosses them in the trash nonetheless, making Darwin sad.
Later that night, Frank and Howdy pop out of the trash, and drag Grady back into the house. Howdy destroys Gumball’s video game console with a bat, making Gumball scream in horror. Gumball angrily asks Darwin why he fished the puppets out of the trash, and Frank responds that Darwin made a promise never to abandon them. Gumball tells Darwin to stop talking to the puppets, but Howdy said he can not because he lives in their world now, and Frank convinces Gumball to play, and both the puppets and the mindless Darwin faint. Leaving no other choice, Gumball puts on Grady, and greets him. Grady then asks Gumball if they should go find Darwin.
Gumball puts his hand on Grady, which transports him to a bizarre puppet world. Grady and Gumball journey their way through the puppet world to find Darwin. Gumball discovers several imaginary characters he and Darwin imagined through their childhood years. They arrive at a bizarre house. Inside the house, Frank and Howdy are playing with Darwin while singing a song about having fun. However, they are torturing Darwin with a dance. Gumball bursts through the house to rescue Darwin, but Grady betrays Gumball and declares that this was actually a trap for him. The puppets say that now it is their turn to play with Gumball and Darwin (now controlled as puppets), who are then tortured by Grady by making them do weird things, like eat toenails and grease, and wear an itchy fleece. Darwin, however finds a piece of string on Grady’s left arm, ripping it off as well as ripping Howdy’s left eye out and Frank’s torso, defeating them. The three puppets all scream and their world explodes, with Grady declaring revenge on Gumball and Darwin.
Back in the animated world, Gumball and Darwin are sitting on the front deck while their yard sale goes on. Billy stops by, and Nicole asks Gumball and Darwin if they are okay with her giving away their old toys, and Grady attacks Billy. Gumball and Darwin respond with “Yeah, pretty sure,” ending the episode.
[The episode starts with Gumball and Darwin in the attic; they are seen packing old toys away, preparing for the garage sale]
Darwin: Why do we have to give them away? These toys have sentimental value! It's not like anyone else will love them like we do!
Gumball: Dude, we've locked them in the attic for, like, seven years.
Darwin: [Finds a Smack-It in the box] Wow! Why did we ever stop playing with this thing? It was awesome!
[Smack-It music plays]
Smack It: Push me! [Voice and music go lower pitched and distorted] Hold me… Squeeze me…
Darwin: Hmm, it never sounded as kid-friendly after we dropped it. [Throws into bag] But look, remember our old digi-pet? [Takes digipet out of box] We had to feed it and change its diaper and stuff. [Presses Button]
[The digi-pet has a blank screen]
Darwin: Mm, out of batteries. [Throws into box]
[The words "CLEAN ME" appear on the digi-pet's screen]
Darwin: [Gasps] Mighty Flyz! The warrior that rules the sky!
[The Mighty Flyz figure goes around breaking things while Darwin and Gumball cover themselves in panic. It flies out the window cutting a wire and killing a bird]
Gumball: [In advertiser's voice] Mighty Flyz takes no responsibility for any limbs, eyes, or innocence lost while enjoying the Mighty Flyz line of products. [Normal voice] What else could we give away? [Looks in box and eyes widen, talks in shock] You've not seen them yet, but no.
Darwin: Seen what?
Gumball: [Insistant] No!
Darwin: [Grabs box and looks inside; gasps] Grady, Frank and Howdy! Aw, Gumball we have to play with—
Gumball: [Even more strict] No!
Darwin: But why?
Gumball: Because we're too old to play with toys and dolls.
Darwin: Playing never goes out of date.
Gumball: Playing with dolls means that you'll never go out ON a date.
[Darwin's expression becomes a sad puppy face]
Gumball: Come on, man. Time to grow up.
Darwin: [Sighs] You're right. I need to learn how to let things go.
Gumball: That's it, trust me, you'll thank me when your teenage years kick in.
Darwin: I know…
[Gumball exits the attic and slams the door]
Darwin: [Giggles in mischief; pulls out the puppets] Hello, guys!
Frank and Howdy, being ventriloquized by Darwin: Hello!
[They all cough, due to the dust that has been gathering Frank and Howdy]
Darwin: Eww, what's that smell?
Frank: Morning breath can be quite bad when you've been asleep in a shoebox for seven years!
Howdy: Come on, Frank! I'm sure Darwin had a perfectly good reason to leave us in there in endless darkness! With only dust mites for our food and our love for him to keep us warm, right?!
[Darwin's head is flattened by an imaginary force of "guilt"]
Howdy: What was that?
Darwin: That was the weight of guilt, Howdy. [Inhales in air, allowing his head to restore its usual form] I'm sorry, we ditched you guys the Christmas we got our first game console.
Frank: That's okay. We still love you.
Howdy: And you'll never put us back in the box, will you?
Darwin: I promise.
Frank: And we will have fun forever and ever?
Darwin: I promise.
Howdy: And you'll never take us off your hands again, right?
Darwin: I promise.
[The scene cuts to Darwin exiting the bathroom, the puppets expressing horrendous shock]
Darwin: Sorry, but you did make me promise.
[The scene cuts to Gumball and Darwin waiting for the bus to come; once the bus arrives, Howdy, still being controlled by Darwin, encounters Rocky, driving the bus]
Howdy: [Dreamily] Ooh! where have you been all my life?
Rocky: Mmm, sitting here wondering what went wrong with mine, while eating cheese.
Howdy: Well… One ticket to kiss-town, please.
[Romantic music plays as they get closer to kiss; Rocky realizes that Darwin was attempting to recreate said music]
Rocky: [Furiously] What the?! Dude!
[Darwin walks away in nervously; immediately his distraction causes him to drive in a path of a truck about to collide. All students scream as they crash into the truck; the scene cuts to Rocky horribly injured serving students in the cafeteria. Darwin walks by, blushing in embarrassment]
Howdy: [Whispering] Call me.
Rocky: [Shaking his head] Mmph.
[As Darwin sits on a table, he struggles to control the puppets in order to eat the sandwich; Gumball enters to sit, placing his tray. Darwin hides the puppets under the table]
Gumball: Dude! The school bus is a total write-off! I guess that's what happens when you put a fifteen-ton vehicle in the limp little hands of a ventriloquist dummy.
[Gumball proceeds to imitate Rocky by speaking like him and flailing his arms; Frank and Howdy, still under the table, pull an angry expression]
Frank: Hey! What's wrong with being a puppet?
Howdy: Big talk from someone so short that you can see his feet on his yearbook photo.
Gumball: [Does not notice the puppets] What's your problem, man? And what's with the voice?
Frank: My problem is that your butt is trying twice as wide as your shoulders, but your brain is half the size of your head!
Gumball: [In disgust] Oh! Anything else?
Howdy: No. I can try to insult your face, but I think nature's already done enough damage.
[Gumball removes the meat from his hamburger, taking the bun out, and proceeds to slap Darwin's face with the meat]
Howdy: At least that solved the problem about eating without your hands.
[The scene cuts to the Wattersons' house, with Darwin taking a bath in the bathroom but still ventriloquizing the puppets]
Frank: Oh my goodness! Who skinned those puppets?
Darwin: [Soft voice] Shh! Those are my socks, and keep it down or Gumball will hear you.
Gumball: [Opening the bathroom door] Did you say something?
Darwin: [Nervously] No.
Gumball: Then who were you just talking to?
[The puppets struggle in the water, making gurgling noises; Darwin persists to reveal them]
Darwin: [Nervously] Nobody.
[As Gumball pulls a suspicious expression, Darwin nervously struggles to keep the puppets in the water; he fails, causing the puppets to emerge quickly and take deep breaths]
Gumball: Ah, I knew it!
Darwin: Guys, you don't even have lungs.
Frank and Howdy: Oh yeah.
Gumball: Darwin, we've been over this.
Darwin: [Exiting the bathtub with his feet censored] You don't understand! They're more than jus—
Gumball: [Hiding from the horrifying view of his feet] Darwin, dude! Can you cover yourself up first?
Darwin: [Blushing] Oh, yeah, sorry. [Puts on his slippers]
Howdy: But Gumball, we are more than just puppets!
Gumball: Darwin, you know who talks through puppets? Crazy people, and people who want to make a living as a ventriloquist. So, yeah, crazy people, basically.
Frank: Gumball, we need you too. Who's gonna play with Grady?
Gumball: Dude, no, just take them off.
Frank and Howdy: [Refusing] No!
[Darwin indirectly assails Gumball through the puppets by beating his face]
Frank: The fun will never end!
Gumball: Darwin, stop!
[Frank shoves a toilet paper roll in his mouth]
Frank: Wait, what are we doing?
Gumball: [Muffles Darwin] Finally! Thank you.
Howdy: You're supposed to fall over, not under!
[Frank throws the toilet paper at Gumball]
Howdy: Frank, stop it! [Hits Frank]
Frank: Ow! No, you stop! [Hits Howdy]
Darwin: You both stop! [Both of the puppets hit each other]
Howdy and Frank: Ow! No, you stop! Yah! [Both hit Darwin, causing him to slip and fall]
Gumball: [Grabs showerhead and points it at Darwin] Aha!
[The showerhead fails to shoot any water]
Gumball: [Sighs] You used up all the water.
[Howdy takes the rug under Gumball, causing him to fall; Frank and Howdy go over to the pedal bin, then Frank is pushing the foot pedal of the trash can to hit Gumball's face with the lid. Gumball seizes the puppets, pulling them off Darwin's hand and causing Darwin to launch into the bathtub]
Gumball: [Exhausted] Darwin, when I said grow up, I didn't mean go straight to the part where you're in a retirement home screaming at chairs and biting the nurses.
[The scene cuts to the frontyard of the house, with Gumball about to place the puppets in a box and to throw them into the trash can; Darwin is desperately preventing him to do so by holding his legs back]
Darwin: [Urging] No, please don't do this! You don't understand! They're alive!
Gumball: [Strictly] No, they are not! [Puts the puppets in the box and closes them]
Darwin voicing Howdy: No! Not the shoebox!
Darwin now voicing Frank: It's almost as dark as your soul in here! No!
[Gumball is surprised by their voices, but later finds out that Darwin is still voicing them in an attempt to convince him back]
Darwin: [Normal voice] Oh.
Gumball: Yeah, dude, they are not the ones who need help. [Exits offscreen]
[Due to the situation, Darwin turns his head down, blushes and sweats; he exits back to the house depressedly]
The Puppets' Resurrection
[The scene shows the Wattersons' house suddenly transitioning into nighttime. While Gumball is soundly sleeping in his bedroom. In the frontyard, the trash can falls off, then appears Howdy, now "alive"]
Howdy: [Now non-ventriloquized and speaking with her real voice] Frank! You ok? You don't look quite yourself!
Frank, as a food container: [In his real voice] Maybe there's something I haven't digested properly. [Vomits a rat]
Howdy: [Surprised] Woo! Frank, wrong body!
Frank: Ohh. [Apparently, his spirit transfers to his correct puppet "body"] Okay! Let's go!
[Howdy and Frank drag Grady to the house, whose spirit is still "unconscious." They open the door, sternly entering the house]
Frank: Okay, the bedroom's just at the top of the stairs.
Howdy: Wait. [Grabs a baseball bat]
[Gumball wakes up and walks down the stairs, frightened at the clanking and banging noise that is heard; it is revealed that Howdy has been destroying his console, along with his The Tale of Zelmore cartridge. Howdy immediately hides at Gumball's presence]
Gumball: [Gasps] Nooohoohoo! [Proceeds to perform cardiopulmonary resuscitation upon the broken console, nervously panting in the process] Come on, breathe! What have you done?! [Welling up tears]
Howdy: We taught that thing a lesson for replacing us!
Gumball: I'm not talking to you!
[The scene reveals Darwin, though sound asleep, unwillingly holding the puppets. The two puppets speak by themselves]
Gumball: I'm talking to Darwin! Why did you fish them out of the trash?!
Frank: He made a promise to never to abandon us.
Gumball: You can't make a promise to an object! That's like getting married to a fridge, or keeping a secret for a shoe, and please stop talking through those puppets!
Howdy: He can't. He lives in our world now.
Frank: And if you want to see him again, you too will have to come and play!
[Both puppets close their eyes, causing Darwin to fall on the floor and transferring themselves to their "world"]
Gumball: [Gasps] Darwin! Wake up! Wake up!
[Gumball then sternly looks at Grady and takes him; he then places his hand inside him, summoning his conscience]
Grady: Thank you, Master Gumball. I missed you greatly all these years. Now, shall we go and find Master Darwin?
Gumball: Wait, how do you know what happened?
Grady: Just because I've been unable to talk does not mean that I have been unable to see.
Gumball: Remind me to apologize to Anais' dolls. They're right next to my underpants drawer. They've seen a lot.
A Whole New World
[Grady puts his hand out; Gumball puts his hand onto his hand, summoning them both to the puppets' world]
Gumball: [Realizes his hand is in a form of a puppet's] Ahh! What the what? What happened to me? Wait-awa? [Realizes his whole body is that of a puppet's; screams in horror]
Grady: [Appears also as a real puppet] If that worried you sir, I advise you not to look down.
[The scene reveals that there are two humans in chroma key green screen suits controlling them. Gumball and Grady look down at them]
Gumball: [Nervously] Okay, Gumball. Focus on the task at hand, not hand! Focus on the task at hand— Ahead! T—Task ahead!
Grady: [Puts his finger on Gumball's mouth] Shhhh... shush. Can you hear that, Master Gumball?
[Howdy is heard off-screen, chanting]
Howdy: [Offscreen] The fun will never end!
Grady: This way.
[Gumball and Grady proceed but struggle to walk, due to their abnormally thin legs]
Gumball: Wow! Look at all the things we imagined when we used to play!
[Scene introduces High Five Guy, smiling]
Hey look, it's High-Five Guy! Ah, good to see you, man! [Slaps him in the face, making him sigh while pulling a disturbed expression]
Gumball: [Gasp] It's Sammy Sunscream, the screaming sun!
[Sammy Sunscream, offscreen, screams in agony while shining upon Gumball and High-Five Guy]
Gumball: [Walks in with a tree] The Tree of Permanent Happiness!
The Tree of Permanent Happiness: I wish I could feel other things.
Gumball: [Gasps] Bird-Plane-Bird!
[Scene shows Bird-Plane-Bird, a creature fused of a plane and a bird; it crows]
Grady: Please stay focused, sir. Master Darwin needs you.
Gumball: Yeah, you're right. So just stop distracting me, Keyboard Dog!
