When playing "Mopemope", a song notable for its music video that suddenly shifts from child-friendly content to glitchy horror elements, part of the aforementioned horror elements are replaced with stock footage of a ferry cruiser due to unspecified "circumstances". This censorship appears to be a reference to the finale of the visual novel School Days LxH's anime adaptation. The episode's scheduled TV premiere in Japan in 2007 was replaced with assorted stock footage, including that of a Norwegian ferry, due to a scene in the episode that unintentionally mirrored an axe murder that occurred the day before airing, spawning the 4chan meme "Nice boat."
