Calming Potion

The Calming Potion is created by the Medicine Man who lives in the tallest tree on Shark Tooth Island. He will only serve you if you bring him the ingredients (see trivia) and if you are wearing a Grass Skirt.

Once you have the Calming Potion, use it with the cannon on Booga Bay (Place) to launch it into the water. The Great Booga Shark will swallow it up and fall asleep, allowing you to safely cross the bay and rescue Professor Hammerhead and his young son.

Trivia

 * The ingredients of the Calming Potion are: Carbonated Coconut Milk, Old Bone, and Key Ingredient.
