Flying crabs are enemies in the Terrarium area of Ripple Dot Zero.
Flying crabs have black shells with two side stripes running from the front to back. They possess three, bright orange eyespots and also have pink legs. There are two black flaps that stick out on either side of their shells, and they have long, thin, light grey wings.
Flying crabs are encountered in the Terrarium, in both Areas 1 and 2. When Ripple Dot Zero moves within their perimeter, they fly towards him. If they hit the penguin, they hurt him on contact and will circle around to attack him again. Flying crabs take one hit to kill and can be seen attacking in groups.
