Gloob

The Gloob are a diminutive race from the planet Gloob.

Biology
The gloob are one of the most interesting species in the galaxy, they are small blue creatures, reaching an average height of only 1'8". Their most distinguishing feature is that their head is entirely independent of their body.

This means that they can carry it beneath one arm as the need arises, or keep it safely sheltered in times of warfare by depositing it in a vault specially designed for that purpose

Equally remarkable is the fact that a Gloob head, if properly cared for, can attain immortality. There are several million heads stored in their memory vaults acting as a giant living supercomputer.
