Pigsticks is the last in a noble line of explorers, and he's decided it's time for him to follow in his forepigs' footsteps--with an assistant to do the heavy lifting, of course. When his help-wanted ad draws a motley crew of candidates, he chooses a hapless delivery hamster named Harold. After a long trek through jungles, over deserts, and up a giant ice-topped mountain, the last crumb of cake is stolen by a herd of thieving goats, and their goal is nowhere in sight. Will they ever discover the Ends of the Earth?
