One moment that stands out is in the trailer is when a boy throws a newspaper on the house's front lawn as he's riding past, muttering "Stupid house." The house apparently throws the paper back at the boy from offscreen, knocking him off of his bike.
This dialogue when DJ and Chowder are escaping from the Monster House.
DJ: (as he and Chowder flee back into his house) Don't look back!
Chowder: (looks back anyway and the house makes a scary face) AHHHH, I LOOKED BACK!
