Why not?

You bite your lip, thinking. Is some expensive jewelry worth it? You could always re-sell it for a decent chunk of pocket money. But a 1/3 chance of being stuck as a girl -- a pregnant girl, no less?

Then again, you had a 1/4 chance just now, and that turned out alright. And 1/3 is still better than a 50/50 chance. You sure could use the money -- you were broke, and couldn't even afford some clothes in a pinch!

After a good few seconds of thinking, you nod. "Alright, sure. But where are we going to... you know?"

"Hmm," the man says, looking around in thought. He snaps his fingers suddenly. "Okay, come with me." He leads you into a bit of a tight alleyway off to the side that seemed like it didn't get much foot traffic.

Once he's sure no one is around, he reaches in his bag and pulls out the small containers again. "First," he says, "choose one of these."
