Wing-slug

Orion wing-slugs was a type of animal native to the Rigel system. They were considered a delicacy by the Orions.

When Gary Mitchell heard that James T. Kirk was being reassigned to the USS Constitution (NCC-1700) to serve alongside him, Mitchell considered himself to be as happy as "a sloppy, fat Orion with a belly full of warm, juicy wing-slugs".
