Epic (2013)

Continuity mistake: As in most movies I've seen where size is a main factor, the animators did not pay much attention to scale. In the scene where the main character leads the leaf people to her father's house, she is jumping and lands on the thinnest pencils I've ever seen. They have the width of the pencil smaller than her foot. However later on, it is shown that a push pin is almost the size of her body.

Mub: What's going on, baby girl?
Mary Katherine: Talking snails.
Mub: Actually, he's a snail. I'm a sluuuug. No shell over here, baby. It just slows me down.

Question: What was hidden in the rolls?
