drowned

This reminds me of a Spanish cartoon, I can't remember exactly everything, but a [beautiful] woman's children died (or never found, and they just called them dead) and she couldn't except it, so her spirit kidnapped children and took care of them. But if someone crossed her pass, she would [try] take our their soul, or something similar to that (I don't think the cartoon really explained). To set her free, they had to show her their grave. Really sad cartoon/movie.
