Ganon's Tower

Morpha

The guardian of the Water Temple is Morpha. In order to defeat Morpha, Link must use the longshot to take the core out of the water tentacles. Then Link must slash the core with the Master Sword several times. After repeating this process several times, Morpha will be defeated. Watch out for the tentacles though, if they grab Link, he will take damage while being held by them, and also if he is thrown at the spikes that line the outer walls of the room.
