Northern Nightmare is a truck that is from Canada in the real life Monster Jam. He is a truck that loves hockey, maple syrup, canadian bacon and even Terrence and Philip from South Park!
He is a truck that has had a rough past, and he is known to go crazy if anybody doesn't have any maple syrup. In the show, he is always making excuses to get it.
For instance, he says that it is his pride and joy, and he must always have it.
But, why? Because he's Canadian. So, that's who this guy really is. See ya!
