The lovable slug Sluggo was on the second episode of Enterprise. He was found by Hoshi Sato on an alien world and brought on the ship as a pet. So, her was a space slug. Frankly, Sluggo was the most fucking interesting thing about the first 2-3 seasons of the show. On the plus side, logic dictates Hoshi kept Sluggo in her quarters - hence he probably saw her boobs. All hail Sluggo.

I may be only an invertebrate from outer space, but I seen her titties.
