Not to be confused with Terrans, the Latin term for Earthlings.

Tyrrans are the only known species of planet Tyrra. They are Human in appearance except for being two and a half inches tall at the most.

During the planetwide famine caused by the Super-Gro incident they held the Lambchop family's ship for ransom until a truce was reached between Earth and Tyrra. Stanley had the brilliant idea to take the Tyrrans and their remaining food supplies to Earth to live until their planet was green again. The current population is six hundred eighty-four.
