21. Little Lemmings

It's cold outside, but Nick and Sally want to keep playing to stay warm out in the cold. Cat's friend Lars the lemming lives in the Wundra-Bundra-Tundra. It's cold out, but with Lars' fur coat, he doesn't even notice and they help Lars find a new home, one where there's more food for him and his family and they discover that he uses the snow to help keep him warm. Back at home, Nick and Sally wear two winter coats to help them keep warmer than hot chocolate.
