The parts of the legs on the left and right deflect the water flow, and each part takes a complex action to create a fascinating wave motion.
The flat body imitates a crab, and uses the left and right arms as balancers to fall slowly while maintaining a horizontal posture.
In order to reproduce the crab's unique falling speed, which is neither too slow nor too fast, the body design has a depression on the ventral side of the body to receive the appropriate amount of water.
