Gr 2-3-- A bland blend of fact and fiction. The subject of this ``autobiography'' is Winston, a handsome bullfrog whose tranquil life on the pond is changed forever when he is captured and placed on exhibit in the Reptile House at the Bronx Zoo. In four short chapters, Winston describes the procedures that zoo personnel follow after his arrival and his adjustment to his new job as a live exhibit for enthusiastic crowds. The prosaic descriptions of zoo operations are uninteresting, and the main character is pretty colorless. Even for an anthropomorphized frog, some of his comments are ill-chosen, such as the trite and patently inappropriate, ``I couldn't believe my ears.'' The brightly hued, cartoonlike drawings are appealingly done; a few, such as the drawing of the frog proudly holding up his long leg to be measured, display a touch of humor that is never fully developed elsewhere. The text is clearly written, but some of the words will need clarification (``sullen,'' ``sociability,'' ``puncture,'' ``stool sample,'' ``parasites,'' etc.). A good factual introduction to a zoo is Machotka's What Do You Do at a Petting Zoo? (Morrow, 1990). --Karey Wehner, San Francisco Pub . Lib .
