Horror Short: Bad Kids Killed by Christmas Monster

by Chris
(Canada)

The name of the movie would be fine but I'm more interested in a specific story within the movie. It focuses on a family on Christmas eve and the parents warn of a monster that will come and take/kill/eat them if they are naughty/said its name too many times/didn't listen to the parents.

After constant warning, the children don't listen and it ends with the monster's hands coming through the living room bay window and killing them.

Any ideas?
