Is the hidden treasure of Tesoro Island legend or legit?

It's real, according to an old-and soggy-message in a bottle, which sends dragon prince Fuego off on a daring treasure hunt to the heart of the island itself. With his sister Oro the crow, he leads the crew of Explorers past the edges of the magic map and into the unknown. 

But they're not the only ones on the hunt. Seven evil hedgehog wizards (hezzards) are hot on their tails, not to mention a mysterious (and really pretty) blue dragon, and a suspicious snowy owl. 

Who will find the Treasure of Tesoro Island? Real or not, here the Explorers come...
