This video of a terrifying and ferocious creature, also known as Marvin, is coming for you this Christmas Eve.

Marvin the Collie, adorned in a sharp-tooth dinosaur costume, rounds the corner in his Austin, Texas, home in slow motion, presumably on the prowl for your Christmas cookies.

As he yawns, or roars, as his owners would like you to believe, the wrath of fear is instilled in anyone brave enough to watch this cuddly dogzilla.
