Here is the answer if you are looking for the Wheres Wally Advent Calendar 2019 answer for Woof’s Tail on day 10.
It’s not actually attached to ‘Woof’, so it really is just the tail you’re looking for. Not to be confused with the Candy Canes attached to a cake at the top of the advent calendar, it’s not them.
Woof’s tail is down at the very bottom, close to the Camera from way back on December 2nd! In-between doors 1 and 24. It looks more like the tail of a soldier dressed in a blue hat with yellow trousers.
