Hyo-hyo ひょーひょー

Hyo-hyo is a yellow-green (occasionally white in animation) creature; her body shape is similar to a bell with ribbons or a sprouting plant.

Hyo-hyo is able to fly using two vertical limbs on top of her head (or her legs) that act like a helicopter propeller. She is capable of carrying weights much larger than herself using her mouth or legs while flying. She's limited in verbal communication, only able to speak her own name, but her expressive variation in tone of voice is usually able to convey her message.
