This dynamic Lego Aquarium features fish that "swim" around the perimeter of the tank, a crab that jumps, and a starfish that spins as the fish pass by. This all happens by turning a crank which operates a smooth and robust mechanism built into the cabinet.

This is part of the Lego Ideas contest and is in hopes of getting 10000 supporters over at https://ideas.lego.com/projects/fa8f50fa -2267-415d-a0ac-d3b441653bf0
