Animated Picture Of Inside The Stomach I'm Looking For An Animated Film?

I'm looking for an animated film? - animated picture of inside the stomach

I remember on television somewhere between 1996 and 2002. He felt very alternative, mostly in black and white with some scenes at the beginning of still images in black and white, was up a Merry Go Round, I think. Enter the characters are small, and the action was had, like the time because of a dark cloud or something stopped. I remember a scene where the dark forces, some office supplies like a stapler or stapling had encouraged to alienate the young actor. I could not have been a cloud, like a Ferris wheel mechanism in it.

That's all I remember them. If anyone remembers this, please let me know.
