Fresh off ripping space-time a new one at the end of Bender's Big Score, the Planet Express crew is back to mend the tear in reality, or (hopefully) at least not make it worse. Beyond the tear, though, lurks a being of inconceivable...tentacularity. What will become of Earth, and indeed, our universe, when faced with the Beast with a Billion Backs? The Planet Express crew discovers a tentacle-covered, planet-sized alien that wishes to copulate with it all the inhabitants of Earth.
