Blooper: Several exist in this half of the episode.
Liam's nose color varies between being pink and black, depending on the scene.
In D.W.'s recollection of the "Frankentist" scene from "Hic or Treat", she is wearing a green and orange Halloween dress, whereas in the actual episode, she's wearing her usual pink dress in that scene. Additionally, Arthur is standing in front of D.W. dressed in his "Frankentist" costume when she shines her flashlight, but the actual scene in the episode had him walking down the stairs to his bedroom while Jane was shining a flashlight on him.
In D.W.'s Imagine Spot of James as a tyrannical king, the pupil of her left eye is gray in the close-up shot of her shocked face after James sentences her to clean out every unicorn stable in his kingdom.
When D.W. is trying to get Tommy to let her enter "King" James' room, there is one shot where the legs of her pantyhose are missing, with only the feet present.
