Air Cretin

The air cretin replaced its ancestor and shrank to half its size. It now only has one massive hydrogen float bladder and lost its legs completely. It will fly either alone or in small flocks, and can be found in open air, but swarms can be found circling bleeding bellyoon nests for shelter and food. When born they are left to fend for themselves on a zeploon, their wing spines are used to fend off any duke yuuvee who might try to take a bite out of them.
