Shnissugah is a small red cobra snake who only appeared in "The Secret Snake Club." He is an old friend of Grim's.
The Secret Snake Club thought he was a giant bully-eating snake and that he could make them kings. However, he can't do anything that they mention in their song, as what they thought was an 8km "cool-kid eating" god was actually an 8cm reptile version of Woody Allen; Shnissugah blames the size discrepancy on confusion over metric prefixes. It is revealed that he is allergic to cats. His house is near Lake Ontario. He doesn’t eat cool kids because they give Shnisissugah indigestion, but he can at least bite cool kids on the big toe. He is very honorable as he scolds the Secret Snake Club for holding Mandy hostage while telling them that they shouldn't do to others what bullies do to them.
He is voiced by Frank Welker impersonating Woody Allen.
