Have you ever wondered what it would be like to be the size of a thimble? Well, Henry Danger’s Riele Downs and Nicky, Ricky, Dicky & Dawn’s Lizzy Greene are about to find out in Nickelodeon’s upcoming holiday movie, Tiny Christmas.

In the film, distant cousins, Emma and Barkley gear up for Christmas Day, but when one of Santa’s elves accidently shrinks them, they embark upon a journey to become normal-sized again or else they will remain tiny forever.

Tiny Christmas airs this Saturday night at 8 p.m. EDT on Nick!
