Continuity mistake: The first four episodes of season two have absolutely no continuity with the show. Prime examples are the fact that Shendu exists again as a statue which had been confirmed to be destroyed in "The Day of the Dragon", the final episode of season one. Next during "The Warrior Incarnate" it is mentioned that not all the talismans were in fact present, such as the dog talisman, when all talismans must have been found, or the events that escalated during the final episode of season one would never of happened. This problem is the extended during the next episode where Jackie Chan discovers the snake talisman in some sort of Brazilian temple - he had already learned of the snake talisman by stealing it from the museum quite early on in season one. The final continuity error is that Tohru goes from friend to foe and then back to friend as if the first four episodes of season two never happened.
Suggested correction: These were "flashback" episodes, not "they never happened" episodes.
Mainstream - S3-E3
Continuity mistake: When Kitty goes to get a midnight snack, her hair is down. But a few shots later, her hair is up in a ponytail.
Continuity mistake: When Shake, Frylock, and Meat Wad return from Memphis, they notice the door of their house has been ripped out and knocked onto the yard (Meat Wad even makes a comment about it). But as they walk inside to Mothmonsterman, the door is back on the hinges were it should be.
Continuity mistake: This occurs in the episode "To Each His Own." Near the end when the gang is eating chili cheese fries, the fries change from half chili half cheese to all chili, back to half and half.
Revenge of the Monsters - S1-E38
Continuity mistake: The episode is about Ty being put on trial for his attacks as the Wirewolf in the episode of the same name. The problem is that "Revenge of the Monsters" is a Season One episode and the episode "Wirewolf" didn't appear until Season Two.
Suggested correction: "Wirewolf" originally aired on October 28, 2000 while "Revenge of the Monsters" originally aired on November 14, 2000. In the context of the show, there's no continuity mistake. When they reordered the show and put them into Season 1 and Season 2, the first 7 episodes of season 2 are out of order (according to original air date). For example, s02e01 aired after s01e14.
Even though "Revenge of the Monsters" aired on November 14, 2000, and as a season one episode, the episode "Wirewolf" is a Season two episode so it still constitutes as a continuity error.
No. You missed the point completely. "Wirewolf" was produced BEFORE (production code 011) "Revenge of the Monsters" (production code 045). Therefore, there is no continuity error for the show. The order of the episodes were then later changed, which isn't the fault of the show. If you watch the episodes in order they were produced instead of the order they're listed in IMDB, there isn't a mistake.
Continuity mistake: I know that Animators re-use backgrounds but it is painfully obvious that when Keitaro and Narusegawa are leaving the exam results posting they walk in a straight line past the same "Ristorante" three times.
