it was your birthday, and while you were having fun with you and your friends you finally were able to have cake, you make a wish you were a baby again as a joke, but when you do you pass out, you then wake up in a nursery as your mom comes out and when you looked in the mirror you realized you were some how an adult baby…. You some how travel to a new world were adult babies are a common thing

Mommy: good morning my birthday baby~
