Pa'u Oricorio has pink feathers. On top of its head is an arrangement of feathers resembling a headdress. There is a larger, similar group of feathers around its waist like a skirt. It uses hula dancing (pāʻū being a Hawaiian word for skirt, especially ones that may be used in hula).

Sensu Oricorio's feathers are mainly purple. The tips of its wings broaden into a fan shape, and it has a fan-shaped crest on top of its head. It uses Japanese dancing (扇子 sensu being the Japanese word for a folding fan as may be used in such dances).
