Swing the Mood! =3
Not a movie, but something that screwed me up either way. Season 5, Episode 1 of Thomas the Tank Engine; during a bad storm one night, a cargo ship runs ashore, running into a shed where some of the trains were staying to stay out of the storm. The shed gets smashed in, and knocks over Cranky the Crane, who was next to the shed. When he fell to the ground and had this face on him, I got scared and cried because I thought he had died! That scene scared me so much, not only could I not watch that episode, but for a very long time, I couldn't watch Season 5.
