Starfish

Tap it to wave its arms. Hands-on: lift an arm and it curls back down slowly.

A starfish, or sea star, is not a fish at all but a relative of the sea urchin. It has no brain. Seawater pumped through canals in its body works the hundreds of tiny tube feet under each arm, which let it creep along and grip rocks, and at the tip of each arm is a simple eye. Many kinds can regrow a lost arm.

Tap it and its five arms lift and curl in turn, like a slow wave, then settle back. Pick an orange, red, purple or blue starfish in the Splash tab. With ✋ Hands-on on, lift an arm and it bends up from its root; let go and it curls back down slowly, as a real starfish's arm does.
