Snowmen at Night by Caralyn Buehner (2005)
Have you ever built a snowman and discovered the next day that his grin has gotten a little crooked, or his tree-branch arms have moved? And you've wondered . . . what do snowmen do at night? This delightful wintertime tale reveals all! Caralyn Buehner's witty, imaginative verse offers many amusing details about the secret life of snowmen and where they go at night, while Mark Buehner's roly-poly snowmen are bursting with personality and charm.
