Trauvaille, The Scientist

This is one of two pages for:  "An evil scientist merman who hates nature but loves purple." Which is a direct quote from a small child whose opinion I ask on what should be next in the series of paper dolls I'm making for my niece. 

I have no idea how a merman gets to the point that he hates nature but Trauvaille sounds like an excellent name for such a fellow.
