Tropical Mer-ponies

My submission for 's contest. When I first read the rules and saw the tropical theme, these little beauties are the first thing that popped into my head! Starting in the upper left and going clockwise, they are the butterfly fish pony, clownfish pony, blue tang pony, and mandarin fish pony.

I can upload the individual ponies if anybody's interested

For the record, I do not own My Little Ponies, Hasbro does.
