What a Knight - S1.E40

Peter and So-So land in an old English town. Peter pulls a sword from a stone and the king proclaims him the defender of the people. When Peter is tasked with battling an ogre he tries to slink back to his balloon instead but the balloon is already airborne. So-So knocks out the ogre from the balloon but Peter gets the credit. Peter then must fight a fierce black knight, who Peter, using his hippo hurricane holler, discovers is just a shrimp on stilts.
