Welcome to Bluebell Woods, home to a delightful cast of woodland friends. Natalie normally has to hibernate each winter, but this year, she's determined to stay awake long enough to have fun with her friends. She is desperate to go sledging and join in with the annual snow-animal building competition. Then she learns from her grandma that once, many years ago, she stayed up all winter - can Natalie persuade her parents to let her go out with her friends when the snow begins to fall?
