EDM challenge: draw a bar of soap

I bought some oatmeal soap a while back to keep in a dish by the sink. About a week ago we saw a few teeth marks in the bar. Thinking whoever was snacking on that soap couldn't possibly feel very good, but everyday the bar gets smaller and smaller. It's obviously a real treat for some rodent who has a feast every night in the bathroom while we are asleep. Life is just different here!
