Crabs
From Zelda Wiki.org
Crabs are small, helpless creatures that you find near the water at Outset Island. They dissapear into the sand (but always come back up) if you get too close. They don't serve any purpose in the game. They are black and purple, and are the only 2-D things in the whole game. To make them go away just do a rolling attack over them. They don't hurt you or anything.
