Why did Peter Pan scatter the contents of the drawer?

Peter Pan has lost his shadow. After the Darling children are asleep, he calls to Tinker Bell, who is hiding in a jug, to ask where it is. She responds that it is in the big box in the drawer. In his eagerness to get it back, which shows the kind of impulsive, enthusiastic creature Peter Pan is, he scatters the contents of the drawer all over the floor looking for it.
He is so delighted to have found his shadow that he closes Tinker Bell into the drawer without even realizing it and forgets all about her. Then, when he can't figure out how to reattach his shadow to his body, the mercurial boy sits down and sobs until he wakes up Wendy. Wendy sews it back on.
