first go into Poseidon's shrine temple thing and put the starfish on the pedestal then go through the door and you should be at a beach dive into the water and you'll be in an underwater maze. Air bubbles will give you more oxygen so pick them up often. to get to the Hydra go down and then up to the right then go down some again you should be at a fork in the path now so go left and down. keep going down until you reach a path going left continually go in a down left direction until you reach a cave and you should be there
You battle the five-headed hydra in the "gnarly monster" cave within the underwater realm of Poseidon. The Hydra will try to strike you by thrusting out one of its heads. When it does, you must be ready to jump before it does, then land on top of the head, knocking it out. Repeat this for all five heads, then swim below to get a scale from the defeated monster.
(*outside and above the cave is the Giant Pearl which you also need.)
If you already found the pearl underwater where Poseidon's palace is, the hydra is right beneath the place where you found the giant clam holding the pearl. There is a sunken ship underwater, and you must go in it to find the hydra ( 5 headed monster.)
