Fuuma

Fungus Face, also known as Fungus Fingers, is Dr. Viper's assistant in the episode Katastrophe. Although he has no dialogue, his growls and snarls were provided by Frank Welker. He was a large creature shaped like a green mushroom, with glowing red eyes, a cat nose and cat ears on top, and several tentacles. He helped Viper break into Megakat Biochemical Labs at the beginning of the episode, ravenously devouring the two security guards on duty. Later, during Viper's time as a member of Dark Kat's Alliance of Evil, Fungus-Face remained close by his master's side and even actively participated in one of the group's schemes to kill the SWAT Kats. Like most of Viper's monsters, Fungus-Face was nearly impossible to destroy: he survived at least two explosions, one which was powerful enough to splatter him all over the Turbokat. Unlike most of Viper's creations however, he was actually (for the most part) sentient, and even had a personality.
