Paolumu is a bat-like wyvern that slightly resembles the Honduran white bat. Like said bat species, Paolumu is covered in white fur and has a pink face. Though it is covered in fur, Paolumu also has some brown scales covering its back, underbelly, and tail. The Paolumu has rodent-like buck teeth this is because its diet consists of the eggs that comes off the coral which it sucks in using its incredible breathing power.
Inside of Paolumu's neck is a special air sac that inflates once it has sucked in enough air. Once its air sac has inflated, Paolumu is able to float in the air like a balloon and able to attack foes from above. While floating, Paolumu will use its hardtail to batter foes at close range. Paolumu is also able to breathe wind at foes, it can also use its inhaling powers to draw in hunters closer or to make them stagger.
