A doll includes a body and a head, two legs and two arms, each movably attached to the body. The doll includes a mechanism connected with the head, with each of the legs, and with the arms. The mechanism is configured to displace the legs frontwardly with respect to the body in alternating succession and to displace the head in lateral directions with respect to the body such that the head moves toward one lateral side of the body as one of the legs displaces frontwardly from the opposite lateral side of the body. Movement of the legs displaces the body of the doll in either a walking or a crawling mode. Further, a motor is connected with the mechanism to drive the mechanism to displace the legs, arms and head with respect to the body. An electrical circuit is connected with the motor and has a microphone. The circuit is configured to drive the motor when the microphone receives sound, particularly a user-generated command. Preferably, the circuit includes an integrated circuit chip configured to drive the motor for a randomly specified period of time. The mechanism preferably includes a gear train having an input end connected with the motor and output ends connected with the legs, the arms and the head. Further, the mechanism preferably includes several separate linkages connected with the legs, the arms and the head, each linkage pivoting the associated appendages or the head with respect to the body.
