One rainy day in the city, an eager little boy exclaims, Rain! Across town a grumpy man grumbles, Rain. In this endearing picture book, a rainy-day cityscape comes to life in vibrant, cut-paper-style artwork. The boy in his green frog hat splashes in puddles - Hoppy, hoppy, hoppy! - while the old man curses the dang puddles. Can the boy's natural exuberance (and perhaps a cookie) cheer up the grouchy gentleman and turn the day around?
