Pigs love to wade in the mud, which is why adding more muddy substance into a bathtub helps them. But you can change its shape when it rolls and falls on each level: making it round will result in collecting food at the same time. When this happens, if Piggy finds his way back up again he will be just as happy as ever! So, sometimes your goal may not always be achieved... but that's okay! It all comes down to how much effort you put into completing your task; even so-called impossible tasks are possible for those who try hard enough.
