Piggy Bill likes sweet potatoes. After each of them, they start to form gasses in his stomach and that leads to urgent swelling and you probably know what will follow next. Try to stay with Bill on the ground that rotates and collect the potatoes to make farting better. Watch where the objects fall, because when they accumulate on the one side they turn the ground to that particular side. Gradually, more and more objects will fall on you. Be careful do not let them drawn you down and do not get stuck in the junk. Have fun.
