I have this very vague memory from many a years ago… I was on vacation in a hotel and I was going to sleep on the coach. My mom left the tv on for me. I was watching what I THINK was an anime, MAYBE. I know it was not live action. 2 characters (maybe a woman and a man) were sitting on a small boat and talking. It was like a canoe. Suddenly, they started swordfighting and I remember heads getting chopped off, but then growing back(???? I could be wrong???). I just remember I got really really scared and I turned the tv off. But yeah….I know that’s super vague of a description, but I’d like to see if I can find what I was so scared of back in the day.
...Moana? Or to stick with the Disney theme, maybe the scene in Peter Pan when Tiger Lily was captured by Captain Hook and Smee.
