The Toon Revolver is an animated firearm used by Eddie Valiant in the filmWho Framed Roger Rabbit. The gun, a Smith&Wesson 625JM Model, was given to Eddie as a present from Yosemite Sam for working on his case, getting him out of "the hoosegow" (prison). After Teddy's death, Eddie quit working for Toons, but still held onto it in the event it might be needed.
Later, Eddie pursues Jessica Rabbit toward Toontown thinking she just killed someone. Tossing R.K. Maroon's gun aside, he takes out the Toon revolver on the realization that he has better shot at a favorable result with a Toon weapon. The ammunition, Toon Bullets, resemble stereotypical old-western archetypes: a sheriff, a deputy, a Civil War soldier, an Indian, a cowboy, and a masked outlaw.
