One rainy day in the city, an eager little boy exclaims, """"Rain!"""" Across town a grumpy man grumbles, """"Rain."""" 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?
