Morpheel

Morpheel is the boss of the Lakebed Temple in. It is a massive eel with several tentacles and an eyeball floating around in one of the temples.

Upon entering the boss room, Link must use the Iron Boots to sink to the chamber bottom, where only the eel's head is seen; sticking out of the sand. The clawshot is used to rip its eyeball out of the gelly tentacles and attack it. After that, Morpheel comes out of the ground and swims around. To defeat it, one must use the clawshot to grapple onto its eye on its head, and stab the eye repeatedly. After a number of blows, it is defeated; its eyeball is destroyed; and with no eyesight, smashes into the chamber's wall and drains the room of water, dying.

Morpheel is very, very similar to Morpha from The Legend of Zelda: Ocarina of Time; the name and form of fighting are very similar, and it may possibly be Morpha's amoeba in an eel body.
