I used to hate this little creep, but he's started to grow on me. (May have something to do with the fact that his owner is so damn sexy!) I like to think he's a baby sandworm; he only looks like a random flying eel thing. At any rate, great rendition, love the pastel coloring on the body and its contrast with the eyes.
I think he is suppose to bean electric eel? He actually is not really flying.
Mozy placed some kind of *Oxygen Spell* to make Xerxes body think he is in water so in reality he is swimming in the air with his gills thinking it's H20. That is why he can loop around so easy in the air because he can do so in water.
How it works I am not exactly sure but it's a science manipulation.
