My wife bought her daughter as a gift, but she didn't know there were no mice in it. IT'S ONLY A TICK! That wouldn't be such a big deal, but the problem is that the mice seem to have sold out or been discontinued and are now being sold by third-party retailers for exorbitant amounts. The cheapest I could find for a mouse was $25. Avoid a headache and get over it. We will return ours.
