Paolumu

Description

After sucking in a large volume of air, this Flying Wyvern takes
on its unique, rotund appearance. That air can then be expelled
to propel itself. It is just as mild-mannered as it looks.

The calm disposition, adorable face, and soft, white down make
some think this is a benign monster. However, it is extremely
hostile to threats and can be quite intimidating.

Paolumu are the only species known to have a neck pouch, a flexible
organ that expands when it inhales. The buoyancy lets it conserve
energy by reducing the number of times it has to flap its wings.
