Extremely abstract concept for a movie from childhood

This is going to be extremely hard to get but I’ll try to add as much detail as possible.

I remember watching the film about 9 years ago (meaning film is 9 years old or older).

The movie was 2D animated, however, I don’t remember if it was regular animation or an ‘anime-style’.

The ONLY scene that I remember is of a child falling into water, the scene had lots of beautiful bubbles and the child was bleeding. I also faintly remember a wolf in that movie but I don’t remember if it was the child bleeding or the wolf bleeding.

If anyone find this I will be ECSTATIC!

no blood, but this scene from “wolf children”?
