She imagines how nice it would be to fly with the birds, bees, and butterflies. She decides that would be a good way to spend the day. Penelope closes her eyes, and she sees herself soaring high amid the clouds, the sun, and the sky. Soon, she is busy as a bee making a variety of new friends in her world.

A picture book for children, The Imaginative Adventures of Penelope Ellerbee shares the story of how one little girl's imagination transformed her into a bee and gave her wings. It shows that no matter what time or even the day, your imagination can always take you away.
