Hollowheads are tiny, delicate animals native to Gamila's Islanda Tropics. They have very short lifespans, living only about a day. Once they are born, Hollowheads lie in the Paddleton Sea and flap their wings, which are covered in a sticky film. They catch plankton and small floaters, which they lick off with long tongues. They then crawl onto land, drying themselves off in the sun, and proceeding to fly away from the beach. They use their hollow appendages to make light clicking sounds, which attract mates. After mating, the host will lay about 20 eggs, before it and the two other Hollowheads die.
