The invention is a toy for use in a body of water, e.g., a bathtub, a pool or the like. The toy comprises a body typically in the shape of submarine, fish or aquatic mammal, e.g., a whale. The toy normally has a negative buoyancy in water and is pivotally mounted in water with its pivot point located intermediate its ends. Means are provided for feeding air to the lower side of one end of the body. The body is adapted to trap sufficient air to impart positive buoyancy to that end, whereupon the buoyant end rises in the liquid and causes the toy to pivot. The gas trapped in the buoyant end is released when that end has risen to a predetermined level.
