As Billy behaves more reckless than ever and can't stop breaking everything in sight, Mandy thinks he should go some place where he can release all his urge to destroy until he gets tired of it. Then, Mandy, Grim and Irwin go to Level 9, home of the fearsome warrior Lord Pain, to convince him to take Billy. Meanwhile, Billy receives psychological treatment and it is revealed that his desire to destroy stems from lack of attention when he was younger. Then, Lord Pain abducts him, and together they start destroying everything in Level 9, which apparently is uninhabited. In the end, Billy is still not satisfied, so he and Lord Pain return to Endsville and carry on breaking everything.
