What is this anime where a poor girl forced is to wash an ugly guest that's very muddy?


I remember a scene from an anime which I can't identify. (I don't remember
whether it was a film or a series.) It was in the style of _The Girl Who Leapt
Through Time_. I watched it about 3-10 years ago but it could be much older.

What I remember: A poor girl works in a public bath and is forced to wash a
special guest who the other girls working there don't want to wash. The guest
is coated in mud. The girl gets help (maybe animals?) / a special soap. She
uses the soap on the customer and the mud vanishes. As a thank-you she gets a
reward. I think I could see gold coins in this scene.

I already went through the list of anime I remember watching but it was none
of them. As this scene regularly comes to my mind, it annoys me not to know
where it's from.




This is presumably the scene from _Spirited Away_ where Sen has to clean the
river spirit. ([here's a crappy camrip on
