"A sweet visual idiom. . . A fast-moving story with two high-spirited heroes, Alexander’s tale prizes imagination, creativity, and quick thinking."

—Publishers Weekly

The premise of an imagination run amok is a tried-and-true storytime winner, and this hits all the right notes from the lively pace to the familiar context to the toylike animals. . . . Rambunctious youngsters will appreciate the cheerful energy here.
—The Bulletin of the Center for Children's Books

Alexander’s exuberant text lends itself perfectly to reading aloud. . . Kiki and Anna’s rapidly shifting emotional extremes are dead-on and offer additional points for discussion. . . . A deftly executed homage to the power children possess to imagine away a dreary day.

—Kirkus Reviews

Alexander’s sweetly cartoonish illustrations are very funny. . . this delightful and imaginative romp will have readers giggling and wishing for Think-Ups of their own.
