After Whitebeard uses the Grow Key to make himself 40 feet tall, the key breaks! So the Wanderers take the key to Wizard Fix-It in Moscow. While mending the key, Fix- It accidentally makes Waldo, Wenda, and herself two inches tall...and loses the key! So begins a Nutcracker - like the mini-adventure in Moscow to retrieve the key from Odlulu and Fritz.

When Odlulu finds out she's on Santa's Naughty List, she travels the globe and tries to spread holiday cheer by adding to various Christmas celebrations. When it turns out that Odlulu's "help" ruins Christmas around the world, the Wanderers must use the Tick Tock Key to go back in time and restore the Christmas traditions.
