In a book that shows one kind of conflict resolution, Hugo, a shy frog with a small croak, learns to be more assertive with the help of a duck. Hugo lives in terror of the big frogs, especially Pop Eyes, a bully who dumps Hugo into the pond upside down, snatches his stick, and splashes him. Duck teaches Hugo to quack loudly when threatened, and the next time the bully frogs come around, Hugo opens his mouth and bellows “QUACK!” The result of this surprising emission is that birds scatter, butterflies flutter, fish flap, and the bully frogs fall into the pond. Church’s art gives the frogs, fish, snails, and worms of this story bright colors and ping-pong-ball eyes, plus the requisite goofy expressions. A funny story, with surprises that will have toddlers giggling. (Picture book. 3-5)
