Castaway Island

Castaway Island is an island that is located off the coast of Booga Bay on Shark Tooth Island. You can only reach the island after you've put the Great Booga Shark to sleep. You will find Professor Hammerhead and a boy stranded there. After leading them back to the mainland, you will receive the island medallion from the boy's mom.

Appearance
The island appears as a large pile of sand with a few palm trees, a small makeshift hut with a clothing line, a few broken crates and a bamboo fishing pole lodged between two rocks. The word 'HELP' is also spelled out on the shore in sticks.

Trivia

 * There are girl clothes hanging on the line. However, there are no girls located on the island.
 * "Castaway" is an obvious reference to the word "castaway", meaning somebody who is stranded.
