Oh What a Knight Rudi and Trudi are flying happily in the sky when something sparkling distracts Rudi. Off he zooms, dropping Trudi along the way. Trudi falls through a castle window, while Rudi collides into Sir Grumpy on the ground and accidentally wedging the good knight's metal helmet tight onto his head. Sir Grumpy and his fellow knights had been about to decide who would become King by competing to see who could pull a sword from a stone. Before they could get started, Rudi pulls the sword out himself in order to remove Sir Grumpy's helmet. In doing so, Rudi becomes King.
