These aliens had somehow discovered Zim's invention, the humungoserum, which is capable of turning anything huge and monstrous with just one drop. They decide to use it to create a monstrous puppy shop on Planet Poochaloo, and try to blackmail it off of Zim by abducting Dib, who they have wrongly concluded must be Zim's best friend. But since Zim and Dib hate each other, Zim does not cooperate. The aliens, convinced he is bluffing, proceed to torture Dib to try and make Zim capitulate, but he just takes enjoyment out of it.
