If it's not one thing, it's another for the deliriously cute Boo and Baa, as witnessed in Boo and Baa in the Woods, Boo and Baa in a Party Mood, and Boo and Baa in Windy Weather. They also get wet and go on a cleaning spree in two other Boo and Baa adventures in the series. These hapless lambs are not the sharpest sheep in town, but they do have heart. A lot of heart. The cartoonlike illustrations are slyly humorous, especially for the eagle-eyed reader who can pick up on the subtle hints dropped, like the underwater rock waiting to be bumped by the boat. Preschoolers will adore reading the simple one-sentence-per-page descriptions of Boo and Baa's predicaments, and will happily recognize the sometimes inscrutable nature of the world they, too, have so recently tumbled into.
