Peahat Larva

In Ocarina of Time, Peahat Larvae (幼生ピーハット, Yousei Piihatto) 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, they die. They will continuously chase Link if not avoided or dispatched of. The shield can fend off these enemies. If not killed, Peahat Larvae eventually get tired and return to their parent plant.

Trivia

 * Peahat Larva are closer to the size of the Peahats from the original Legend of Zelda than the normal peahats in Ocarina of Time.
