BUTTERFINGERS

Benjamin Butters drops everything—balls, his toast, his goldfish, the eggs he's collecting, etc. But when (to everyone's consternation) ``Mom'' lets him hold his new baby sister, she's perfectly safe. This new British illustrator has a witty way with a pen, but the idea is overextended and the outcome not well developed. Still, kids may enjoy Benjamin's many comic mishaps, rather mercilessly caricatured in the lively illustrations. (Picture book. 4-8)
