Elmer's New Friend

A number of fun board books aim to entertain the very young. Elmer's New Friend by David McKee is the latest addition to the series starring the patchwork elephant and his friends. The jungle is abuzz with animals eager to find out the identity of Elmer's new pal, and with each question, they gain a new clue. As the black-and-white checkered elephant, Wilbur, points out, ""But, Elmer, if you have a new friend, then we all have a new friend."" A mirror in the last page reveals the answer. (Mar.)
