Does it search the globe for my best match and then teleport them in place of the frog, or does it create a new person entirely? Because those are two completely different things which would change how I weigh the decision. Or is there a chance my true love is stuck in a frogs body? If that is the case I'd be more inclined because I would feel sorry for that person who is stuck as a frog.
Also is there just one frog and does it disappear after use? If so I may be inclined to sell it on ebay.
