A toy snake that reproduces the natural movement of a snake as it moves across surface is described. The toy snake comprises a head 2 that is pivotally mounted to a tail 4 and a motor unit 9 located within the head 2 for propelling the snake across a surface. In a preferred embodiment a body 3,5 is employed to pivotally mount the head 2 to the tail 4. The motor unit 9 may comprise at least two independently driven wheels 15a & 15b located towards opposite sides of the head 2 and the motor unit 9 is configured to introduce a periodic oscillation between the operation of the independently driven wheels causing the snake to move forward while the head oscillates to the left and right producing a rippling effect that flows down through the body of the snake. The motor unit 9 may also be configured to operate a tongue 12 that extends out from the head 2 to further increase the realistic nature of the toy. Embodiments of the snake may be adapted for use on land or water. |
