Crystal Island

Crystal Island, featured in Croc: Legend of the Gobbos, is the fifth and final, or secret island of the game. This island is only unlocked once the player obtains all eight jigsaw pieces from the previous eight secret levels by finding all six Gobbos from all normal levels. These levels are unique to other levels in the game, as no Gobbos or Jigsaw Pieces are required; the only objective is to complete the levels. When the player has completed all five levels and defeated the final Guardian, The Secret Sentinel, the game will be 100% completed.

Trivia

 * The island's first four levels are themed after the four islands, with And So The Adventure Returns mimicking the Forest Island, Diet Brrr in a similar style to the Ice Island, Trial On The Nile themed like the Desert Island and Crox Interactive like the Castle Island.
