A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid. The device having a body with a top side adapted to be at least partially disposed above the surface of the liquid, and a bottom side adapted to be at least partially submerged below the surface of the liquid. A vibration mechanism is disposed in the body. A propulsion fin is connected to the body. The fin includes a top side adapted to be disposed at least partially above the liquid surface, a bottom side adapted to be disposed at least partially below the surface. The vibration mechanism is adapted to oscillate the free distal end of the propulsion fin upward and downward.

A water toy includes a water toy main body. The water toy main body includes a first waterproof integrated box. The first waterproof integrated box is configured to accommodate an electronic element. The first waterproof integrated box includes a first upper shell, a first lower shell, a sealing member, and a waterproof chamber. The first upper shell and the first lower shell are covered with each other. The sealing member is arranged at mounting ports of the first upper shell and the first lower shell. After the first upper shell and the first lower shell are covered with each other, the sealing member seals a gap between the first upper shell and the first lower shell to form the waterproof chamber. The first upper shell and the first lower shell are detachably connected through a clasp.

The Water Window allows for the viewing of objects that are 1 to 4 feet deep, at the bottom of beaches, lakes and streams, by placing the device on top of the water and giving a clear magnification of objects that are available to be viewed and picked up by children and adults alike and treasured forever.

The present invention concerns a water toy for children that floats and combines features of a human with an animal. In one aspect of the invention, the toy has two parts, one with animal features and another with human features. The animal features are separable from the human features. If a child has several of the toys, they can mix and match to create new characters. There is a diverse group of both animals and humans so that a child with several toys can create a large number of different characters. One or both of the parts of the toy are fabric covered for easy cleaning and fast drying. The fabric can be removed to allow for washing in a washing machine.
