Onbu

Onbu was an infant Onbaa that was taken from its nest by a hawk and later found by Naruto. Onbu was a bottomless pit who could eat non-stop. Onbas grow quickly and when an adult, it loses all of it's childhood memories, but Naruto was able to help him by taking him to specific places. Onbu's favorite food is Naruto (the food). Then after moving in a circular motion, suddenly Onbu remembered his childhood past by looking at the Uzushiogakure crest on Naruto's back.
