Surf’s up and Mrs. Armitage is ready to do the California slither, Bali swerve, and Waikiki flip. All she seems to need is the perfect wave, as well as some snacks, a windsock, a float, and a megaphone, among other things. She gets a real work-out as she swims to shore each time to gather the items she and her loyal dog will need for the Big Wave. Readers gladly go along for the trip: The resourceful heroine brings spunky, funky fun to a simple day at the beach. Blake, in a gleeful mode, flaunts his signature wackiness in an avid display of Mrs. Armitage’s kitschy taste and ingenuity—the megaphone is for flirting, of course. The anticipation has a payoff, too, as Mrs. Armitage puts her clutter to work to aid a helpless swimmer. The heroine’s no-sweat attitude, along with Blake’s humorous details, are the perfect combination for beach blanket fun. (Picture book. 4-8)
