Abstract
Abstract A toy for use in water and on solid surfaces having a casing formed in the shape of some amphibious animal, and a working unit removably installed therein. The casing includes a pair of rudders, shaped for instance like the wings of a penguin, and a water tank which, when containing water, enables the toy to swim underwater. The working unit contains a switch mechanism, which can be operated by means of a lever extending through the casing, electric cells, a motor, transmission gears and the like. The motor rotation is conveyed to a pair of flat-shaped foot members through gearing and shafting. These foot members can be slid along the arched bottom of the working unit and fixed at different positions, so that the toy is capable of making variety of motions in water besides walking on solid surfaces.
