This got a little out of hand. xD
Anyways, my (first) entry. This little guy is a highly intelligent sea mammal. He's covered in fur that sheds water like a duck's feathers, and it helps him survive in cold waters. Most of his species live in saltwater rivers or lagoons, and they've developed flower-like growths on their tails over generations. The flowers release a highly toxic hormone into the air that in small amounts provokes unconsciousness and memory loss. This particular specimen has learned to use this to his advantage, robbing trade ships coming into harbor while their passengers are fast asleep. So yes, he's a bit of a pirate. (:
If you want to see the unshaded version to get a better idea of his design, just let me know! :D
