Karakoro

Karakoros are enemies from The Legend of Zelda: Link's Awakening. They appear exclusively in the Color Dungeon, a bonus dungeon found only in the DX version of the game. Karakoros must be properly defeated in order for Link to progress through the dungeon. However, Karakoros cannot be killed with any weapon. Instead, Link must strike them with his sword to make them retreat into their shells. He must then use his sword to knock them into color-coded slots in the floor. Karakoros must be knocked into slots that match their colors. If a Karakoro is knocked into the wrong slot, it will pop back out, come out of its shell, and resume its attack. Once all Karakoros in a room have been knocked into slots in the floor, they will fall into pits below them and the room's doors will open.
