Slime Eel is the boss of Catfish's Maw in Link's Awakening. Its mace-like tail sticks out of a hole in the ground and spins around, attacking you, while its head crashes through the walls. In order to attack it, you must use the Hookshot on its head to pull it out, and attack the part of its body with the heart on it. Sometimes a fake eel will come out of the hole, run like a Moldorm, then explode. After a few hits, the Slime Eel will be defeated.
