Labion

From Space Quest Omnipedia

Forested planet, full of indigenous wildlife, including Pinkunz, predatorial monsters such as the primitive Labion Hunter species, Labion Terror Beasts, and other more unidentifiable flora and fauna. The planet is orbited by a cloud of asteroids, once employed by Vohaul in his door-to-door salesmen scheme.

There are no signs of an indigenous civilized culture (aside from Vohaul's presence there), yet there are mailboxes posted conveniently around the planet.
