The twin offspring of Mr. and Mrs. Badd don't exactly live up to their name, but they do have quite an adventure when--instead of napping--they bounce and rock their bed out the door. Their trip downtown includes stops at the bakery (where Mrs. Tasty Pastry ""gave them cookies with frosting on top/From the Tasty Pastry Bakery Shoppe/And a chocolate Ã‰clair to share""), the ""super brand-new Bijou show"" (popcorn), a hamburger joint (""And an order of fries to share""), and the ""Noah Badd Read-A-Book Nook,"" where Dad ""gave them each a nap-time book."" Then it's home for a kiss each and ""a nice big blanket to share."" As the wheeled bed careens along, the gleeful cartoon-style illustrations burst with energy; the plot is an adequate vehicle for the catchy, rhythmic text, lilting like Mother Goose with internal rhymes and repetitions. Adults may find the bug-eyed babies off-putting, but young listeners will be entranced with their junk-food goodies and taste of freedom.
