Cave Art

I've been trying to get all marking utensils clear out of the kids reach to prevent incidents like this one from occurring. However, a purple crayon must have slipped my grasp and I ended up finding cave drawings all over the tv, wall, and chair. The chair was the one I could laugh at the most so I'll post it. Jacob says it is a picture of the temple. I can kind of see it too, but still... I'm not sure mr clean magic eraser will work for this one.
