Spill some chlorine bleach on the bathroom floor and let it sit there, and all the stains will disappear in under 30 minutes. (Make sure to ventilate the bathroom unless you want to pass out from the fumes.)
If your bathroom floor is not bleach-safe, use peroxide creme developer (the same kind you dye your hair with) on a rag. Get on your hands and knees, and scrub.
The paint on the walls, well, if the Magic Erasers the person above me recommended don't work, you may need to repaint the spots on the wall. It's not as big a deal as it sounds - just go to the store and buy a small can of paint and a paintbrush. Even a can of spraypaint can do the trick.
No one has to know ;-)
