Do you know where your butt is? Morty the penguin has no idea! He's pretty sure he has one, but where 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. Morty goes on a wild trip from the South Pole to the steamy South American jungle, and then to outer space to find the answer. And he finally does...in the most unexpected way.
