Great Booga Shark

The Great Booga Shark (or simply Booga) is the main antagonist in Shark Tooth Island. Oddly enough, Booga has a collar. He has a fishhook through his fin that doesn't seem to hurt him.

History
The Booga shark is a huge shark in Booga Bay. He seems to be old, because it is said that he:

"...used to be worshipped long ago and still prowls the waters today."

Defeat
The Booga shark is defeated by giving him a potion created by the Medicine Man that makes him sleep for a large period of time.

Shark Tooth Island
Professor Hammerhead and a boy are trapped on a deserted island. After you give Booga the potion, he will fall to sleep, you can see giant green bubbles popping from the water from where he is sleeping, he seems to never wake up. Then, you swim over to the farthest island, where you meet Professor Hammerheadand and the boy. They will follow you back to the island, where you will be rewarded.
