This is a 25th anniversary re-illustrated update of Tedd Arnold’s first picture book by the same title, telling the tale of young Walter, who lives in a tall apartment building and learns the hard way that perhaps he should have listened to his father when he was told, “No jumping on the bed.”  Instead, Walter jumps so vigorously that he proceeds to crash through the floor of his bedroom, into the apartment below, continuing to fall clear through to the basement, collecting startled neighbors to fall with him through each floor along the way.  If you don’t already have this classic, it’s fun, and a worthy selection for the library, but to be quite frank I preferred the original illustrations, so if you’ve already got the older one, you don’t need this one, too.
