Medusa

Medusa is a gorgon (a female human-like creature with snakes for hair) featured on Mythology Island.

Role In Mythology Island
When you and Hercules enter Mt. Olympus, Hercules sees a small snake and attempts to get rid of it. As it turns out, the snake was actually Medusa, who appeared and promptly turned Hercules to stone.

Items
You can get Medusa's hair in the store. Also, there is a Medusa Surfer item you can redeem with a special code that comes with Poptropica Adventures for Nintendo DS.

Percy Jackson and the Lightning Thief Ad
Medusa also makes an appearance in the Percy Jackson and the Lightning Thief ad as a major antagonist, except here, she has red rays of light radiating from her eyes.

Trivia

 * She came in 4th place in the 2011 Villain Showdown.
 * In real life, her name is Tracey West. She wrote the book Poptropica: The Official Guide, as well as many other Poptropica books.
 * In original Greek mythology, it would be impossible for Medusa and Hercules to meet as Medusa was decapitated, and therefore killed, by Perseus, Hercules' ancestor, before Hercules was even born.
 * One of the items players can get by redeeming a code from the Poptropica Adventures for Nintendo DS game is a Medusa Surfer costume.
 * Despite being a villain, she doesn't stand in the player's way at all, she simply turns Hercules into stone out of annoyance.
 * Because of her minor role and very brief appearance, there is no known way to customize her (excluding the snake hair that can be bought in-store and the redeemable costume that was loosely based on her design)
