Orb Monster
From Zelda Wiki, the Zelda encyclopedia
Karakoro (カラコロ) are shelled enemies found exclusively in the bonus Color Dungeon in Link's Awakening DX.
They usually move around the room to hurt Link. Link must knock them with his sword and throw them into matching-color holes. When they are all in their holes, various things could happen such as making a chest appear or opening a door. Unlike the green and red ones, there is only one blue one in the whole Color Dungeon.
