A horse gets trapped in a small room with a stool and an insect, and together they create a very boisterous situation. The horse and the insect are both scrambling frantically to get out of the small room, knocking the stool around all over the place.
At the height of their boisterous sounds, there's a sudden, awful CRONCH(!) and you see the soul (そう) of the insect slowly rising out of the room, through the ceiling.
