Talk to the minotaur.
Mythology Island.
The minotaur is in the cave with the numbers on a wheel, in the Sphinx Garden.
The Minotaur was a myth invented by the Greeks.
The only doors on Mythology Island are at the temples of Hades and Poseidon, and on the Minotaur's lair.
The red-eyed snake challenge is in the lair of the Minotaur.
The ring is in the minotaurs nose. EWW
The Minotaur is in his lair on the left side of the Garden of the Sphinx. You will need the reed pipe (flute) to open the door.
When you get out of the labyrinth, talk to the Minotaur and he'll give you his ring.
To get the ring you play a song to get it to give it to you or find a specal feature
Talk to the worker at the Hades temple. He will pay you one drachma to clean the graffiti. This is the only coin you can get, and you use it late in the game when climbing Mount Olympus.
The scorpion is in the Minotaur's maze, the Labyrinth, but he is easily jumped over.
