While watching Dragon Ball Z recently I noticed that the premise of the episode Princess Snake is undoubtedly similar to an episode of Boruto (which I don't think has aired in English yet).
Both episodes feature snakes disguised as attractive and unreasonably hospitable women who plan to prey on their guests. I don't feel like I can explain it well enough, but if you watch both episodes I think you'll understand why I feel like there is probably some well defined cultural context that the writers derived their works from, like a folk legend or a popular work of fiction.
I tried Googling to find out but I only found stuff about snakes with human-female heads and snake-brides. I'm very curious and its really bugging me that I can't figure this out. Does anyone here know if or what the snake-hostess narrative is based on? I imagine that there are other shows that have used the same plot that I'm not aware of.
P.S. From looking on the Naruto Wiki, I think the Boruto episode is #75, but I don't remember for sure.
