Mac Millan asks Josh to come up with proposals for a new line of toys.
He is intimidated by the need to formulate the business aspects of the proposal, but Susan says she will handle the business end while he comes up with ideas.
Josh becomes increasingly entwined in his "adult" life by spending time with her, mingling with her friends, and being in a steady relationship.
His ideas become valuable assets to Mac Millan Toys; however, he begins to forget what it is like to be a child, and he never has time to hang out with his best friend Billy because of his busy schedule.
Fleeing from her, he then finds his best friend, Billy Kopecki, and convinces him of his identity by singing a rap that only they know.
