Sammy Mantis is an anthropomorphic praying mantis who is best known for his hit single "The Mantid Man Can" and for gnawing people's heads off. Stimpy is Sammy's biggest fan, as Stimpy attempted to do anything to get his head gnawed off by Sammy. He is based on entertainer Sammy Davis, Jr.

He appeared in "Dinner Party" and "Sammy and Me".
