Geographically, the story unfolds in an unspecified outdoor setting, likely a garden or field. The caterpillar's journey takes it through various food items, from fruits growing on trees and vines to processed foods, suggesting a blend of natural and human-made environments. This mix of settings allows young readers to connect the caterpillar's experiences with both the natural world and their own familiar surroundings.

Specific locations within this broader setting include the leaf where the caterpillar hatches, the various plants and trees bearing the fruits it eats, and finally, the cocoon where its transformation occurs. These locations provide a simple yet effective backdrop for the caterpillar's growth and metamorphosis, mirroring the developmental stages that young children experience.

Characters

• The Caterpillar: The protagonist. He begins as a tiny, very hungry caterpillar who hatches from an egg. Throughout the week, he eats through various foods, growing larger each day. After overeating on Saturday and getting a stomach ache, he eats a green leaf on Sunday. Finally, he builds a cocoon and emerges as a beautiful butterfly.

• The Butterfly: The transformed version of the caterpillar. After spending more than two weeks in a cocoon, the caterpillar emerges as a large, multi-colored butterfly, representing the completion of metamorphosis.

• The Foods: While not characters, the various foods—from assorted fruit to cake and ice cream—play a significant role in the story, illustrating the caterpillar's growing appetite and the passage of time.
