Peahat Larva

In The Legend of Zelda: Ocarina of Time, Pea Hat Larvae are emitted by sleeping Peahats in Hyrule Field at night or by a Peahat that has flown high into the air. They attack from above and if they land on the ground they die. They will continuously chase you if not avoided or dispatched of. If not killed, Pea Hat Larvae eventually get tired and return to their parent plant.
