The team who brought grins to young readers with "The Boston Balloonies" and "I Met a Moose in Maine" have created a third charmer about a family of codfish and their friends. According to Shankman"s rhyming narrative: The Cods of Cape Cod / Love their summer vacation, / And though they could go / Anywhere in the nation, / They keep coming back / To their favorite location, / "Cause they know that Cape Cod"s / A vacation sensation! The Cods of Cape Cod / Have a house on the beach, / And it"s just the right size, / With a fish tank for each. . . . To this colorful fish-friendly house come the Cods" many fishy friends, shrimp comes from Sandwich, bass from Mashpee, swordfish from Chatham, and so on. And boy, do they know how to have fun!
