Santa's Little Yelper?

Ewan was trying to catch Santa out in mid-delivery last night. He didn't manage it, that wily Santa not only managed to sneak into the house without the aid of a chimney, a detail that I didn't elaborate on incase I was taken up on it, but also across less than a couple of centimetre square patches of visible floor, with a reindeer and manage to scoff the mince pie, milk, carrot and water.

Ewan was sitting up periodically right through the night but still didn't manage to see the big man.
