The marine aquarium consists of a large bowl of water that can also be filled with water. The carousel platform is rotating. The carousel is loose and is not connected to the water tank below the dome. The four-leg clamps ensure a stable hold of the figures on the carousel. The fur seal can move the fins of the head and tail up and down. The front wings are rotating. The fur seal can go through the belt and balance a ball in the support. The belt can be taken directly with a figure in the hand or it can be attached to the support at any point of the sealing strip of the tank.
