Melmacian Slug

Melmacian Slugs are a non-sapient species of cow-sized gastropods from the planet Melmac. They produce slug juice.

Biology
Melmacian Slugs are large creatures which have organs resembling a cow's udder and two pairs of eyestalks. Despite having no legs, they can stampede and move at great speed. They feed on mayonnaise, which exists in natural underground sources in Melmac.

Following the destruction of Melmac in 1985, this species is most likely extinct.

Cultural significance
Melmacian Slugs are raised as farm animals by Melmacians, who enjoy the slug juice produced by them.
