Invader ZIM: Roboparents Gone Wild 

End credits are obviously from Soapy Waffles for the only purpose of having end credits and music at the end of the episodes and are not the actual credits to the creation of this video.

GIR blows something up in an electrical accident. This accident is near the closet in which the Roboparents are kept. This jolts their "brain chips", making them act like real human parents. Zim realizes this after he is tossed out of the house for being "bad" and is then replaced with a freakish mutant animal, which had escaped from a zoo. Zim disguises as this animal and manages to shut down the brain chips of the Roboparents, leaving them broken, like they were before the electrical jolt.
