I'm not sure if this will help, but they used to play a song on the radio when I was a child. I think the name was "It was a one eyed, one horn, flying, purple, people eater." I don't remember anything else about that song. Using the above description, I would say it would look like a purple, Cyclops, Pegasus, Unicorn, with big vicious teeth! Or, maybe it would look something like this.
