Neon

This sea slug duo is a humanoid character who wears a living sea slug buddy as a hood, or - when the sea slug gets a little huggy - it is worn as an engulfing onesie. They explore the oceans together and love fishing. The name for the slug is "Globby." The human has no name.. or an apparent gender, it seems (a cool reference to the androgenous nature of sea slugs in real life)! The human also has tentacles attatched to their body somewhere, so they hang out of their baggy tropical-print shorts. If either of the two become upset, Globby's special bioluminencence flares up, causing an aggressive neon reaction and a scowl from their human friend.
