Morpheel

Morpheel is the third boss found in Twilight Princess. Located in Lakebed Temple, Morpheel is only superficially like Morpha, from Ocarina of Time. Morpheel's first form is simple. Avoid the explosive fish he shoots out at you, then grab his eye with the Clawshot. Slash it like crazy. Repeat. After a couple of these, the tentacles will retract. Check out the water around you, and he will emerge, a giant hungry Eel. His eye will get swallowed, to end up on his back. Swim above him, and use the clawshot to grab his back. Slash away again. You'll be thrown off. Just do this a couple more times, and he'll go down like sushi.

By defeating Morpheel, Link will recieve the third and final Fused Shadow and another heart container.
