The Ultimate Vampire Resource and Directory

The original versions of the team appeared in the hundredth episode, One Hundred, when the 100 Monster sucked them into a universe where they were "re-tooled" as Aqua Unit Patrol Squad, and a parody of Scooby-Doo. Each of them were given a new name as well. Master Shake was renamed "Captain Pistachio", Frylock was renamed "Fry-Boy", and Meatwad was renamed "Meaty-Meaty Moo". A fourth member was also added to the team, Tabitha, who somehow became a member since she "came with the van", and Shake claims that she was his girlfriend (she is a parody of Velma Dinkley from Scooby-Doo.) At the end of the episode, the 100 Monster kidnaps her, takes her into the woods, and rapes her and beheads her ("possibly not even in that order").
