Bortle's Species

Bortle's species are sapient race of three-eyed alien from an unknown planet.

Biology
Judging by Bortle whose the only notable member ever shown of this specie, they have more than two eyes; at least roughly three, their bodies are mostly a whitish-grey color with an orange dorsal crest on the back of their head and four tentacle-like hindlimbs. Apparently, burping is highly contagious to them and they're able to suck things up like a vacuum and their diet appears omnivorous although they favor insects.
