When one duck gets "stuck in the muck, down by the deep green marsh," she calls for help. First two fish come to her rescue, then three moose, four crickets, five frogs, and so on, until finally all the animals realize they must work together to help the duck. A strong verbal pattern that uses a rollicking rhyme and plenty of onomatopoeia makes this funny counting book a good choice for a group read-aloud story. (Ages 2-5)
