Morty is pretty sure he has a butt, but where exactly IS it? So he does what any reasonable penguin would do: ask. But no one in the South Pole can help--not the other penguins, not the polar bear who shouldn't be there, and definitely not the seal who wants to eat him for dinner. So Morty goes on a wild trip--from his frozen home to the steamy South American jungle and finally to outer space--to find the answer. And Morty finally does . . . in the most unexpected way. His crazy adventures will make kids laugh their butts off
