When the Roboparents present themselves as zookeepers in order to prove to the other Skoolchildren that they have jobs, Zim has to quickly create a zoo outside his base in order to maintain his cover. However, the other children are unimpressed and grossed out by the hastily created fake animals of the zoo, and accuse Zim's "parents" of being grifters. Dib, meanwhile, takes photos of the fake animals to the police; when they refuse to listen to his explanation of Zim being an alien, he repeats the grifter rumor, which they take seriously.
