A strange question involving (SPOILERS)....
... the dog. Ok, so he ate the clown nose by accident, thinking it was a piece of food. As a result, he turns into a clown-dog, and almost attacks the mom before the man (who's brother once fell under the clown suit's curse) decapitated him. That same man says that once the father eats 5 children (something him and his brother gave into), the suit would come off and he would go back to being a person and not a clown-demon. That said, had the dog eaten 5 children, would he have just been able to regurgitate the nose up and be a regular dog again?
Also, the father made a dramatic physical transformation as a result of the clown suit (chalk white skin, multi-colored hair, even colored blood). The dog didn't seem to make a physical metamorphosis. Granted, it was a darkly shot scene in a semi-lit room, so it would've been hard to tell anyhow. Did anyone notice any changes on the dog, or are we supposed to assume that the dog was (mentally) changing?
I'm so scared your little head will come off in my hands!
