Koalanyan is a koala with a blue swirl on it's belly, a small aquamarine colored wisp shaped tail, and wears a collar just like Jibanyan does. Koalanyan's collar sphere is greenish blue, though. His nose is dark green and his fur is the same color as the swirl on his belly.
Koalanyan seems to like to dance and can only communicate using his own name and "puku puku". He has the ability to transport himself and other people between the real and cartoon world via a simple boop on his nose.
