Lucy, a tutu-clad bear child, begs her mother to allow her to keep a small boy she finds in the forest. Despite the titular misgivings, Mom relents, and Lucy and Squeaker (all he ever says is “squeak”) play happily together for a time before—surprise!—problems emerge. Squeaker is “impossible to potty train” (he glowers from the litter box), ruins the furniture by jumping and tearing it apart, throws food at tea parties and then disappears altogether. Heartbroken, Lucy searches for him, and when she finally finds him with his human family, rightly decides to leave him there, concluding, “I guess some critters just aren't meant to be pets.” The art, with narration in green text boxes and conversations in pink speech balloons, was created with pencil, construction paper, wood and computer. Squeaker, perhaps intentionally, is undeveloped and unconvincing, but the blocky bears are appealing. The story lacks depth and subtlety, although young children may find the role reversal hilarious, and the catchy title and ’50s nouveau art provide a soupçon of charm. (Picture book. 4-7)
