Providing children with extraordinary visual experiences and immersing them in a marvelous world of underwater exploration. It is perfect for children aged 12, 13, 14 and above.

The shark body is connected by three joints. By rotating the knob on the base, the built-in gear system can drive the head, body, and tail of the shark, bringing it to life. In addition, the shark toy set has a neon light on its body, which lights up in green when you toggle the gears on the right side, giving you a marvelous visual experience.
