Mika put his hand on Luka's shoulder and joined in the incantation. The elf's nose twitched. It's body seemed to twitch all over. It's ears grew longer, and hairier. Coarse white hairs covered the elf's body as he grew bigger and bigger. He was becoming a horse like Luka intended, but at the same time something was off. Whoever heard of a horse with a beard, and there was definitely a beard growing from his chin - well, muzzle. The elf was taller than a mule, but not quite as tall as the other horses. Then there was the nub or nob in the middle of his maned forehead. It started to grow. It erupted through the skin. It was a horn. By the time the spell was complete, Luka and Mika had transformed the elf into a unicorn.
"Dang, I didn't know you could create unicorns?" Mika said to Luka.
"Can't or couldn't. Guess, it's the nature of the elf. He couldn't just become a horse, he had to become a unicorn. I wonder if all elves become impossible things? Next one we get, I'm gong to transform into a pig. I bet it'll be a pig with wings- or maybe that would have to be a fairy. Are there pig unicorns?"
"I don't know, Luka. I'm not sure we should have done this. I mean unicorns are magical animals, how are we going to keep him. Don't you have to be a virgin to hold a unicorn?"
"A virgin?" Luka said thoughtfully looking at Mika.
"Oh," said Mika.
