Continuity mistake: There's a scene at the beginning with an old man and a dog sitting on the porch. Not only does the dog go from looking right to left from shot to shot, but in one shot he actually gets up and almost completely leaves the frame, and in the next shot he's laying down again.
Continuity mistake: In the police station, after the Klown squirts Mooney with the yellow flowers, Mooney says "So you wanna play games, eh?" If you look at the bottom of the screen, the flowers are still there, but then the the shot cuts to a wide shot, and the Klown's arm and the flowers are gone.
Answer: The actor is Randy Doke. He's uncredited for the role, but IMDB lists him as "Puppet Show Dude."
