Abstract: A game machine includes a number of movable assemblies, a storing portion for storing the movable assemblies and a mechanism for reciprocating the movable assemblies between a home position inside the storing portion and a turning position outside the storing portion. Each of the movable assemblies is in the form of an animal and includes a pair of members simulating respective jaws of the animal. One of the jaw members is povitally supported relative to the other for simulating opening and closing a mouth of the animal and a mechanism applies a biasing force for pivoting the first mentioned jaw member away from the other jaw member thereby to simulate opening of the mouth.
