"So what now?" I asked, clutching the stone, "are you going to try and take it back?"
Mikey shook his head. "You're bigger than me. And there are too many things you could do with the stone to threaten me. But you know, there is something you could do. We could share the secret and you could have your wish."
"Really?" I replied.
"Sure. We could be twins, for instance."
I was ready to wish for that when it occurred to me. "You're trying to trick me!"
Mikey shrugged innocently. "I am?"
"Yes. You didn't plan for me to have this stone. I have this stone because you traded lives with me. And you didn't figure out that when you traded lives with me I'd get the stone. If I just wish us to be twins, that means you'd have the stone back, or at least have a good chance of getting the stone back. Well, I wish that however I'm transformed, I keep the stone and you can't take it."
Mikey gulped.
"Now I wish...."
