You jump on its heads.
Wait until the Hydra tries to attack you with one of its heads. Jump up and land on top of the head, knocking it out. Repeat this for the other four heads and then swim over to get the Scale that you need. (Outside the cave is another sacred item, the giant pearl.)
There is no scale. I have already beat it.
Talk to the minotaur.
You can't.

The Hydra is a large, five-headed monster that lives in a cave in Poseidon's realm. You must travel to the underwater realm and make your way to the Hydra (gnarly monster) cave. Beat the Hydra by jumping up when it tries to strike you with one of its heads. Landing on top of the head knocks it out. When all five are beaten, swim down and take a scale from the beast. Note : the Giant Pearl is just outside the cave.
Sorry there is no easier way to beat mythology island. the best way is to find the things in order on the list and do what people tell you to do. tips: on the river of styx crossing it is the easiest to do when you are tiny and you crouch down by the ferry guy when the celling falls and when the green glowing skull comes but jump when the monster attacks then assume previous position do this 3-4 times) thats all:)
no there is no way at all
Jump over it and move right, where you can exit the pit.
you jump on each head to put it to sleep
zues is god in mythology island. he was a mean dude. bonus. in order to beat him you must have hades crown and poisods Triton.avoid his lightning and hit him with yours. tada
The Hydra cave is in the realm of Poseidon. Use the starfish from his statue in the museum, and cross the beach to Aphrodite. Beat her test and then enter the water, swimming left then down into the underwater maze. (see related questions)
On Mythology Island in Poptropica, the final thing you do is defeat Zeus in a battle to stop him from taking over the island. Once you defeat Zeus, you will have completed the main quest of the island and can claim your medallion.
