Go! Go! BoBo Shapes

Basher brings his distinctive line of informational books to an even younger audience with the introduction of BoBo, a marshmallow-headed little guy with an urge to bounce (a bandage on his forehead suggests a propensity for accidents). In this outing, glossy shapes appear at left, while BoBo bounces past them and into scenes in which they are featured (he splashes out of a pool of water containing boats with triangular sails, careens between rectangular flat-screen TVs, and launches himself into a clump of heart-shaped balloons). It's a vibrant and playful primer on the topic. Available simultaneously: Colors. Up to age 4. (Apr.)
