A crossbreed between the two coolest things evar; a unicorn and a pegasus. It contains both main attributes of each animal. They have both a swirly horn and wings on a horses body. The animal is very endangered and some people believe they do not exist, but they do. One cannot fathom the thought of riding on a unipegacorn, unless infected with The Geat, so don't even try. There origin and genetic makeup is pure awesomeness.
Whoa, did you see that unipegacorn?!?
My favorite thing to do is play water polo on my unipegacorn after a long day of hunting beaver-sharks.
