Plot
Early one morning, a grouchy ladybug challenges a friendly ladybug to a fight over which one of them should eat some aphids for breakfast but then decides that the other bug is not large enough to be worth fighting. It then travels around the world and encounters a series of increasingly larger animals, such as a yellowjacket ("wasp" in the British edition), a stag beetle, a praying mantis, a sparrow, a lobster, a skunk, a boa constrictor, a hyena, a gorilla, a rhinoceros, & an elephant challenging each to a fight but then declining & deciding to go looking for a bigger animal. Eventually, it encounters a whale, who at first doesn't answer, but then it slaps the ladybug with its tail & sends it flying back to where it started. The wet, tired, & hungry ladybug then decides to be nice & shares the aphids with the friendly ladybug. The friendly ladybug says to the wet, tired, & hungry ladybug that it has saved some aphids. It then tells the other ladybug that it can have the aphids for dinner.

The book is unusual in that the size of the pages are not the same throughout the book, rather; it increases with the animals' sizes throughout the book. Also, the whale's tail takes up a page in itself & turning it is meant to represent the slapping motion. The time of day is also shown at the side of each page.
