The story follows a predictable pattern: the narrator sees a cow, who says “MOO!”; the cow sees a ghost, who says “BOO!”; and so on. Other characters include an owl and a cat who, upon slinking into a house, sees a baby in a highchair. The cat greets the baby, and the baby says “GOO!” to follow the pattern. Having just finished a meal and a bottle, the baby soils its diaper and creates an alarming smell—the house erupts in chaos, attracting the baby’s older sibling and mother (who is light-skinned). Finally, the baby’s father (who is dark-skinned) saves the day with a diaper change, eliciting the final word of the book: “PHEW!” This simple picture book excels as a tool for early speech and literacy development. The consistent rhyming pattern helps children learn to interpret a sound with a variety of spellings. The dialogue follows suit, continuing the pattern without seeming forced or slipping into more internal rhymes, and the silly story adds to reader enjoyment. The addition of a little green stink bug on every page makes for a fun engagement tool. Borkun’s full-color, original illustrations are approachable and appealing to young readers. Additional activities help guide parents on how to best use this book to support language development.
