Pippi
About
Gender: Male
Pippi is a light yellow bird. He's the pet of Ooshima.
Pippi often bites Ooshima, and only Ooshima, being perfectly tame with others. At first, this led Hinata to wonder if Pippi even likes Ooshima, but after watching them longer, he notices Pippi never leaves Ooshima's side, and concludes he must like him after all.
