Pan

Pan is a Satyr on Mythology Island and the Greek god of the wild. In Mythology Island, he is featured as the ghost of a dead satyr. He lives in the Labyrinth. He will help you with the bone puzzle by giving you an ominous clue - "Remember, there is more than one way to read the bones", hinting to use the bones to spell out the word "TEN".

Trivia

 * Pan being located in the Labyrinth might be a reference to the 2006 Mexican-Spanish dark fantasy film Pan's Labyrinth.
 * Pan, being a god, is much larger than most satyrs.
 * In the Battle of the Labyrinth, Percy Jackson series by Rick Riordan, Pan died in the Labyrinth. Which might be why his ghost is in there.
