this is a Sea Cleaner, my contribution to the Color Alliances: New Mythology project (run by the loverly SavvyPanda).

Although the colors might be a bit washed out here, I think it's still obvious that I'm on Team Orange

so, about the Sea Cleaner: they are a type of marine mammal, and although they are very adept at swimming they prefer to walk on the ocean floor. Their legs are very unproportional to their bulky upper bodies, but their large tails help them to balance when they walk. Sea Cleaners are not very social creatures when they are active during the day, but at night they retire to underwater volcanoes in groups of hundreds. They are so named because they eat mostly rubbish that collects on the sea floor, like rusty cans and old license plates, and they have been known to flock to oil spills (oil being a delicacy among their kind). But despite the fact that trash constitutes most of their diet, they prefer giant squid and shellfish.

oh, and apologies for this terrible scan- I'll have a better image than this in the near future.
