Island Head Beast

The island monster is a creature Dipper and Mabel encountered in "Tooth."

History
In "Tooth" Dipper and Mabel set out to find the creature after finding its tooth on the shore. Later that night the twins notice bubbles in the water near a small island. The ground starts to shake, and the twins begin to row away. As they do this, the island floats out of the water, revealing it to be a giant floating head. The camera shuts off as the head approaches the rowboat. Later, the camera is found on the beach. Dipper says the giant head thing sunk back into the lake after it attacked, and it lost another tooth trying to eat their boat.

Appearance
It usually sits beneath the water, and appears to be an island, but when it levitates it looks like a giant human face with glowing eyes. It also appears to be missing a tooth.

Trivia

 * When played backwards, it says something around the lines of "You have awoken me from my slumber! Enter my mouth, children. Enter your destiny! RAAAHH!!"
