Fifi tries everything to get her little sister Peanut to let her play with her new blue ball. Grabbing it doesn't work. Neither does wheedling, "Pleeeeeaaaase." She gets a wastebasket for basketball. She makes the ball a hat. She pretends to be a fortuneteller in need of a crystal ball. Peanut is interested in none of it, until Fifi returns with a seal named Bob and big plans. "We can teach him tricks and join the circus and travel all over the world!" Peanut is in, just as Fifi decides she'd rather do something else. But all is well by the end of this droll picture book in which the spare palette (muted green, blue, and orange) and spare style of the digitally rendered figures on cream-colored pages have a sensibility both nostalgic and futuristic, in addition to their obvious humor and charm. (Ages 3-6)
