The Serious Clownfish

Marvin is a clownfish who absolutely REFUSES to acknowledge the irony of his species name. While his cousins are out there being funny and entertaining, Marvin has decided to dedicate his life to being as serious and stoic as possible.
He has a permanent frown (or what looks like one), takes himself incredibly seriously, and gets personally offended when anyone mentions the word "clown" in his presence. He's basically the emo kid of the reef.
