At 40:23, Frieda tells all the villains in the castle to bring Cinderella to her. The giant then says that they're nocturnal villains and that they only work at night. What makes this false is the scene at 23:56. The giant is walking around during the day and steps on Jack and everyone knows for a fact that the giant isn't nocturnal because in the original story of Jack and the Beanstalk, he's doing things during daytime (same for some of the other villains).
At 23:56, Jack is smaller than the giant's foot and gets stuck to his heel but then at 28:33 and 28:41, he's as big as the sole and is under the arch.
