What has happened is that when his mom comes up and sees Jim she recognize it's Jim. But she ask who is this. What happens is Jim starts to explain he didn't even realize that he was peeing. His mom says that it looks like you have alot more growing up to do. She remembers that Jim's sister had been watching the neighbors toddler.
She tells him that he can be this age until tomorrow that way you can think of what happened to you and what you will do when you get changed back. His mom then goes and tell Jim to stay where he is because she needs to get something. When she comes back she has brought a pair of training pants. Jim says me not need training pants me big boy. He didn't even realize that his mind is regressing also.
His mother tells him that it's either them or a diaper. She then tell him that while you had been talking to me you had peed with out think about it.
She sees that it is just about time for Jim's dad to come home so she tells him to go into your sister's room and watch tv. She had went into Jim's room and found the instructions for the ball and she read it and found that if a person is transformed for more then 12 hours that reality would change to fit the new form the person is in.
She then grabs the balloon and the goes and starts to head downstair again but is sort of surprised to hear what sounds like a show that is programed for toddler's.
