The episode begins at Pop and Cub's house, where Pop is seen giving a milk bottle to Cub. However, the bottle slips from his hands and lands in the middle of the street. As Cub retrieves his bottle, he is unaware that an approaching vehicle is coming. Pop reacts to this quickly, and pushes Cub out of the way, only to have Cub get shredded apart by a street cleaner driven by Lumpy. Because of this, Pop yells out "NOOOOOO!" into the skies.
Later, inside a garage, Pop is seen building something. When he's done, it turns out to be Cub, now a robot who is as tall as their house (now called Cubtron). Pop and Cubtron decide to go into town. While walking around, Pop spots an arts and crafts store, so Pop tells Cubtron to stay, while he gets something. While waiting, Cubtron decides to entertain himself. First, he rips open a school bus and pulls out Cuddles, who is laughing. Cubtron then proceeds to press Cuddles' body against a building, killing him and spreading his blood. Cubtron then picks up a screaming Petunia and Giggles from the school bus, and they suffer the same fate as Cuddles. As Pop comes out of the arts and crafts store with a box of crayons, he notices what Cubtron just did. It turns out that Cubtron used the bodies of the victims like crayons to make a drawing of himself holding his father in his palm. However, Pop does not approve of this, so Cubtron picks up Lumpy's street cleaner to erase the drawing. But this also causes Lumpy to fall out, and break his legs in half when he hits the ground. With his legs broken, Lumpy proceeds to crawl away.
As Pop watches TV on a flying Cubtron, the TV is displaying a monster attacking the city. The monster and Cubtron stare at each other menacingly, and charge at each other, indicating they're about to attack. However, Cubtron instead jumps onto the monster's arms so it could take care of him. The monster is happy to oblige, and tears off a container on a water tower to feed him (like a milk bottle). Suddenly, Cubtron begins crying. His loud crying causes nearby windows to shatter with one of the shards cutting a crutch-toting Lumpy's head in half. Pop is unsure on what to do, so the monster decides to repeatedly pat Cubtron's back. This causes Cubtron's tummy to rumble and beep rapidly, indicating something big is about to happen. As Pop embraces for impact, Cubtron lets out nothing but a short burp. Just when everything seems fine, Cubtron begins vomiting. His vomit splashes on Mime, Toothy, and Disco Bear, and the vomit is so acidic, it causes the three's bodies to be reduced to skeletons, and making their heads burst. The vomit is also strong enough to burn down and destroy all the buildings.
Sometime later, the entire city is destroyed, and amidst all the damage, the only thing not destroyed is Pop and Cub's house. The monster has resorted to becoming Cubtron's adoptive mother, as it wears an apron and has just finished making a batch of cookies. As Pop asks Cubtron to let him sit on his lap, Cubtron proceeds to do so, unknowingly crushing his father offscreen.

- Even with the 3D animation, gravity doesn't apply to Pop's pipe when he opens his mouth.
- When Pop pushes Cub out of the way of the speeding truck, neither of their hats fall off their heads.
- When Lumpy's head is sliced by glass, his brain doesn't appear, unless the sliced part of the head has the brain inside.
- Disco Bear's head explodes last, even though he was the first to touch the vomit.
- When Disco Bear, Mime and Toothy are killed, the street sweeper can be seen for a second with Lumpy in it, even though it's supposed to be empty. This was probably done for comedic effect. Even more strange is that Lumpy died.
- When Cub dies, his mouth is upside down.
