- Nebbercracker's flashback about how he met Constance and freed her from the circus.Nebbercracker: I can take you away from here. Would you like that?Constance: Yes...
- The moment leading up to said flashback. DJ tells Nebbercracker that he knows about Constance, and while Nebbercracker is understandably pissed that the kids went into his house, he almost immediately calms down when DJ asks, "You didn't kill her, did you?" Nebbercracker's response is a sad smile as he whispers, "I love her so much..." Note how that statement is not in past tense. Even after everything that's happened, Nebbercracker still loves Constance as much as she still loves him.
- The house may be a raging beast who doesn't hestitate to devour anyone or anything in its path, but since it is actually being posessed by the spirit of Nebbercracker's late wife, Constance, it genuinely cares for Nebbercracker.
- Near the beginning of the movie, when Nebbercracker has a heart attack, the house begins to moan, almost sounding like a woman crying. It may also double as tearjerker, but it's still kind of cute how despite Constance being dead, even in house form, she is afraid to lose the one living being who ever cared for her.
- When Nebbercracker returns from the hospital, the first thing he does is greet his house/wife, and it begins to move its shingles and trees, demonstrating how happy she is to see him again.

- Also, the scene where Nebbercracker yells at the house to stay away from the kids, it walks towards him at full rage, but hestitates to attack him. And when Nebbercracker starts talking to it, the house actually listens to him, with a sad expression on its face.
- After the kids destroy the house and free Constance's soul.Nebbercracker: Forty-five years. We have been trapped for forty-five years! And now...we're free. (laughs) We're free!!! Thank you! Thank you all!
- Jenny kisses D.J. full on the mouth just as hes about to destroy the monster house. The kiss was short but it leaves him starry eyed and grinning ear to ear.
- When the cops emerge from the remains of the destroyed house, one of the cops is shaken by the experience but the other tells him that they shouldn't talk about the experience and should go "inspect" some candy however the young cop doesn't get the metaphor and they both agree to eat candy.
- At the end of the movie, Nebbercracker and the kids start returning the things he confiscated from others, including the tricycle that belonged to the little girl at the beginning.
- The reveal that Nebbercracker was Good All Along. And wasn't scaring these kids away because he's a child hating Jerkass, but because he didn't want them to be eaten.
- Regardless that even Chowder starts thinking they're too old for Halloween, D.J. genuinely decides that it wouldn't hurt to Trick-or-Treat one more year.
