Grimace is a figure who appears in McDonald's advertisements. He is a chubby, purple creature of unknown species with short arms and legs. He is well-known for his sluggish demeanor. His favorite term is "duh" before every statement. In advertisements, he was voiced by Frank Welker and, on occasion, Larry Moran, and in the VHS series "The Wacky Adventures of Ronald McDonald," by Kevin Michael Richardson. Patti Saunders played him from 1971 to 1984, and Terry Castillo played him from 1984 to 2003.
