Hard Way:
Okay, Make sure you have at least 6 eggs with you. Now when The monster does the vine
thing, go to the wall opposite the monster and hit that wall in the correct spot with the
egg. The egg will fly across the water and hit the X on the monster's neck.

Easy Way:
Before The door closes and Kamek comes, Hit the monster (Not yet in it's monster form)
with and egg (you have to jump to do this).

When Kamek leaves, you jump on top of the boulder, then when the big purple things comes
down jump out of the way and fire an egg and the flashing tounge when it goes back up
