Bi-Cranial

The Bi-Cranials were a race of two-headed humanoids native to the planet Bi-Crania. Scrad and Charlie were a Bi-Cranial.

Biology
Bi-Cranials are almost entirely externally identical to Humans, except for the presence of a second, smaller head attached to a long, flexible neck protruding from their backs, almost identical to the primary head in everything except size. Both heads are fully sapient, with distinct personalities, although only their "normal" head appears to have control over their bodies. Their secondary heads only appear to have control over their neck, able to independently move it around and turn.
