Great Booga Shark

The Great Booga Shark (or simply Booga) is a shark, whose species is unknown. Oddly enough, Booga has a collar. He has a massive fishhook through his fin that doesn't seem to hurt him and his tongue hangs out of his mouth like a dog. He may be a reference to the megalodon - a massive prehistoric shark. Booga is the main antagonist of Shark Tooth Island.

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. This potion is made with Carbonated Coconut Milk, an Old Bone and the Key Ingredient which is hidden in a ruined temple. (Shark Tooth Island)

Role in Shark Tooth Island
After you give Booga the Calming Potion, he will fall asleep. Giant green bubbles pop from the water from where he is sleeping and he does not wake up, making it safe for you to swim over the bay. You then swim over to Castaway Island, where you rescue Professor Hammerhead and and the lost boy. They will follow you back to the main island, where you will be rewarded the Island Medallion.
