Charlotte is given a piggy bank by her aunt, who also puts in a coin to start her savings. "Silly present," thinks Charlotte later as she shakes the pig to try to get the coin out. "Don"t do that," says the pig, " it hurts." The piggy bank is magical and promises that if Charlotte saves enough money she will get a wish. Charlotte finds all kinds of ways to get money for her wish, including hoovering for her mum, and washing Mr Grant"s car. But at the end, the treacherous piggy doesn"t let her keep her savings: he flies off with them himself, leaving her nothing - not even her wish.
