Hatchytron Z

Cub is seen giving a baby bottle to hatchy, but he drops it on the road, Hatchy goes out to reach it, but a car is coming, Cub then moves him out of the way, only to have cub become decapitated by a street cleaner driven by Lumpy.

Later, Cub revives him as a giant robot, named Hatchytron. Cub then sees some crayons, and goes to the store, while Hatchytron is waiting, but Cubtron sights a bus containing Raymond, Nutty, and Ice cube. Hatchytron uses their gore to make a picture for Cub, but Pop is disappointed by this. So, Cubtron picks up Tennis ball's street cleaner to clean up his picture, in which, Tennis ball also falls out of the street cleaner and breaks his legs on the concrete.

Cub is then seen watching TV on Hatchytron. There is a monster in the city, and Hatchytron fights it, but the monster feeds Hatchytron, then makes Hatchytron burp, resulting in a nuclear level, destroying almost the whole city except for Cub's home, by vomiting all over the place.

hatchytron and the monster continue interacting, and the former ends up sitting on cub, killing him offscreen
