Mobo
From Multiversal Omnipedia
The Mobo were a subspecies of monkey bird who inhabit the Isle of Mobo, who have small, stunted wings and are incapable of flight. Although initially it was not known what caused them to develop such tiny wings, it was eventually revealed that this was due to the toxic stecca fog that surrounded the island. When Ren and his crew came to the island in search of the Sixth Treasure of Rule, the Mobo worshipped Niddler as their new king because he had wings. After the recovery of the Sixth Treasure and the defeat of the Ferix, the stecca fog surrounding the island dissipated and Tula was able to use her ecomantic powers to make the Mobo's wings grow back.
