Peat, a toad, and Paul-Paulette, an earthworm, live in the woods beneath the roots of their friend, Christy, a Christmas fern. One day they are dug up and carried away. Christy is replanted in a pot large enough to hold Paul-Paulette, but Peat is too big to get in and cannot completely hide. He stays under Christy's fronds, but can't disappear.

Together with their wild flower friends, they are taken to the Washington National Cathedral to participate in the annual Festival of Flowers. While the plants are being carried into the cathedral, Peat is discovered, picked up and left in the Garth - the small, enclosed garden near the base of the stairs.

This is the story of the little toad's adventure as he tries to find his plant and animal friends in the huge building. It is a tour of the cathedral and an introduction to cathedral architecture inside and out. A short glossary of architecture terms is included.
