Maru the cat loves to play with the drain of the sink. It is not the most hygenic thing to play with, so his human mother plugs the drain, so Maru can't reach in to touch the drain.
Maru is not so pleased with the plug. He keeps digging and digging, trying everything he can to get the plug out, but the plug does not budge. It is amazing how patient and persistent Maru can be for his "toy".
