These three are all of the versions of the title card from the episode “The Enciridion!”
The first version was so horrible that they knew the censors would never allow it, it was basically used as a Censor Decoy for the second version.
The second version is what they were hoping would be approved, but the censors were still picky and denied that one too. (I didn’t include the other one like this since it looks exactly the same… except with bread instead of a knife…)
The last one is the kid-friendly version that the censors finally approved of.
