A young guest in the home of an elderly relative, wreaking havoc that's actually caused by animals that come alive from her precious artifacts, isn't new; still, Bush develops the idea imaginatively, with energetic drafting and a comic spirit that pleasantly recall the art of David Small. Little James (formally clad in suspenders and tie) is left with tea and macaroons while his aunt finishes a letter. A bear rug comes splendidly to life, while a slew of other wild figures emerge from paintings and other ornaments as James tears around the elegant house, leaving everything awry. Fortunately, Aunt Prudence is unperturbed—``I should have expected it...Your father was no better.'' Then, companionably, she plays mazurkas while James and the bear dance. A promising debut, with engagingly offbeat, childlike humor and a sure hand with the lively art. (Picture book. 4-8)
