I love this, if only because it's been too long since I've heard about penicorns. I guess we predicted clopping, huh? Anyway, it's great you made a plush like this. You wouldn't think of genitals as being stuff made for those things. Anyway, it's just great to look at. I like how it's implied you killed a real one.
It must be difficult for those things to procreate. I like the X eyes. It's just a funny design. I now notice how important the scrotum is to it. Yep, these guys should appear in more flash cartoons here!
