Because of the sparkling pail that hangs from the curl in her tail, Darling the Curly Tailed Reindoe joins Santa Claus and his reindeer as they fly through the skies on Christmas Eve. At first, she gets scared and then she gets sleepy and even worries about Santa when he disappears down the chimneys. It's a night full of adventures for young Darling, but the long night has a very happy ending.

When he spies a cheese snack that had been left for Santa, Billy must choose whether he will be "naughty or nice." When Billy does the right thing and doesn't take the cheese, Santa rewards him with a special surprise on Christmas morning.
