When snow covers the ground, Mouse is out for adventure while Mole stays warm in "another winning installment" of this Geisel Honor Award-winning series (Booklist). The snow has made the world outside into a winter wonderland. What better day for Mouse and Mole to go sledding, whirl around on ice skates, and build snowmen together? But Mole does not want to go outside. Too cold! Too windy! He prefers to stay as snug as a bug in a rug inside his nice, warm bed. Mouse is lonely. Ice skating and sledding just aren't as fun for one. Then she gets an idea…a Sno-Mole might do the trick! Mole won't be needing his hat or scarf or mittens…or will he? Sometimes even best friends want to do different things. But at the end of a cold winter's day, it's nice to know that your best friend will be there waiting for you, with warm mittens and all.
