Return of the Sacred Beasts - S3-E22
Continuity mistake: At the end of the previous episode, just after Marcel opened the hole in the ground, an overview shot showed the Duel Ghouls that were approaching, in a vertically aligned queue, with no more than two beside one another. At the start of the episode, the queue appears to be more horizontally aligned, with the Ghouls positioned side-by-side. (00:01:57)
