Gremlins

Gremlins are an unusual Goblinoid Species, known for the adaptation of thin membranes on their arms that allow them to function as wings, much like those of bats.

Description
When standing upright, Gremlins rarely surpass 3 feet in height. Like most goblinoids, Gremlins have large, nocturnal eyes. Gremlins' ears are typically large and forward-facing. They're uniquely sensitive among goblinoid ears, giving Gremlins an incredible perceptive ability.
