Snow has fallen and the pond is frozen, so Arnold knows that—as a bear—it's time to hibernate! But Louise insists that he'll miss all the fun winter things if he does, so she convinces him to try hibernating like a chipmunk instead. They'll sleep for a short time, wake up to go sledding or have a snowball fight, and repeat! The only problem is, Arnold can't seem to keep his eyes open. What if he can't stay awake for the winter fun? Exciting, easy-to-read books are the stepping stone a young reader needs to bridge the gap between being a beginner and being fluent.
