* "Oxenbury is in fine form here. . . . Donaldson's spare text is perfect for read-alouds, and the title character's dialogue is full of catchy rhymes. Little ones will clamor for this one again and again. A lovely option for storytime or one-on-one sharing." --School Library Journal, starred review

* "Donaldson knows that less really can be more, and her straightforward, occasionally rhyming narration is all the setup her peerless collaborator needs. Oxenbury paints Mama Frog as a don't-mess-with-me matriarch whose decisive physicality . . . instantly establishes her as a force to be reckoned with." --Publishers Weekly, starred review

* "The gleeful, unrepentant culprit is sure to make children giggle--then pause with Mama Frog's response. The text's tone, plot, and repetitions are perfect for the youngest readers. The artwork is a masterful match, with humorous, exquisitely rendered body language and facial expressions. . . . The final, wordless double-page spread is a joyous affirmation of life and friendship. A winner for libraries everywhere: home, public, day care, preschool, and school." --Kirkus, starred review
