Ppung Mountain

The absolutely irresistible temptation of farts! Once you fall in, you cant escape? A picture book tasting the fun of farts. In the stuffy city, people on a bus look troubled. Everyone seems to be holding something in. The bus runs and runs until it arrives at Ppung Mountain, and people hurry up the mountain as if something is about to happen. When grandparents and children climb Ppung Mountain, even animals and bread and trains start moving.
