I still can't believe that, in this PC age, they got away with the "Mystical Spellbook" legend on a kids' show. Ordinarily I would applaud such flying in the face of good taste, but it wasn't funny, it was just stupid.
And yes, I had the same reaction to the title. This episode is about the KKK?
Judging by the title, I thought "The Plumed Headdress of Cosarara" might be interesting. Then I watched the episode. Idiotic legend about King Ludwig's horse, and a pretty bad temple run.
