Hibou's are half-owl, half-human and are pure myth, or so most people think. Hibou's have the ability to summon owl's and shoot owl's out of their armpits and hands. They also shoot their droppings at people and their favourite food is rat. Hibou's diguse themselves as music teachers and will kill you if you don't listen.
Hao gave Mrs. Heroux the finger during music class so she transformed into a hibou and shot owls at him.
