Jeremy's new ball game

Jeremy is spending another weekend at his BB's house. Last night she called me from Target because Jeremy had found another baseball tee that he wanted. I told her that Jeremy already has 2 plastic bats, 1 real metal bat, 3 real softball gloves, a tee that shots balls and a real softball tee, and countless balls. I didn't think he really needed another softball tee. BB just said, "well, Jeremy said that he needed it." Of course, when grandparents are in the situation, who needs logic... the kid said he needs tee. So, now we have another baseball tee thing. I'm not going to try to explain what it does because I'm really confused, but I do understand it sings and talks and the balls are fuzzy.
