Princess Maddie and Princess Audrey Live in a Treehouse Castle

Princesses Maddie and Audrey live in a treehouse castle. They meet a grumpy, hairless sock while out exploring one day. Then a frog gives them magical light-up hair, and makes the grumpy sock happy by giving him rainbow hair. They go back to their treehouse, see Neil Armstrong on the moon, missing a sock, and realize the sock they found was his.
