What is Peter Pan's shadow like and what does it mean?

The shadow scene in Peter Pan is a perfect example of the play's playfulness and cartoonish nature. For instance, the shadow, in contrast to the insubstantial shadows of real life, has an actual substance of its own. For example, Peter's shadow is snapped off by the window, and then Mrs. Darling rolls it up and stores it in a drawer without a second thought. This sequence of events is obviously impossible and goes against the laws of physics, as no one's shadow can be detached from his or her body and then rolled up like a yoga mat. However, this scene sets a tonal precedent for the rest of the story, showing us that the world of Peter Pan is one dominated by a playful rejection of the real world. As such, this shadow scene acts as a jumping off point that teaches us to adjust to the fantastical, child-like world of the narrative.
