How To Play The Game Shrek Bug Bounce - Launch Your Bugs At Shrek

About Mr. Mouth, from BoardGameGeek:

Mr. Mouth is a children's action game. A motorized frog head rotates in the center of an X-shaped board. Each player uses a spring-loaded hand affixed to each arm of the X to propel plastic housefly pieces into the frog's mouth, which periodically opens and closes. The first player to flip all ten of his or her flies into the frog's mouth wins.
