Mysterious Alien Creature

"Mysterious Alien Creatures" is a designation given to a species of sapient humanoids.

Biology
There is no significant information on the species, but they seem to drink carbonated naturally-occurring liquid on their homeworld, have highly elastic bodies, and communicate via whistling. Macs also really enjoy pointing at little white blond boys in wheelchairs as they roll down hills at top speed towards their death.
