Baxil is the light green, introspective and environmentally sensitive one. In case you haven't been paying attention here, the author's three for three so far. They took some liberties with the body shape, though. I haven't looked that chubby since three lifetimes ago. (Aside: Baxil lives on planet KAPX. Should I go put on my sunglasses now?)
For the record, I think I'm going to make "Hello human boy! I am Baxil, from planet KAPX!" my new signature quote.
