The episode "Night of Wishes" took place years after the series' regular time
The flashbacks they had were from "five years ago" but the Cozy kids seemed to be at the same age they were in the series' present time. When a spell is broken, all humans lose their memories about the events the spell caused
Think about it; every episode the wizards unleash another spell onto the city, yet none of the inhabitants ever seems to wonder why so many strange things are happening in their city, nor do they ever seem to recall events from a previous episode. The reason? They magically forget all about the spell as soon as it is broken, or else shortly afterwards. This is made even more clear with the mayor after his "Freaky Friday" Flip with Bubonic. I mean; he switched bodies with a wizard, thus discovering that magic is real and that there are a wizard and a witch living in his city. Even an incompetent buffoon like him should be able to put one and one together and deduce that Bubonic and Tyrania are behind all the weird stuff that's going on, but he never acts on this knowledge. Why? Because he, like everybody else, has his memories about the whole event erased shortly after the spell is broken.- Alternatively, the Mayor might be afraid people wouldn't believe him if he tried to expose Bubonic and Tyrannia and/or was afraid of what they'd do to him.
- Well, Maledictus T. Maggot didn't remember being an Abhorrent Admirer after the spell making Tyrannia attractive failed so it's indeed possible they don't remember.
- This was all-but-confirmed in the episode where the city becomes a game show; the Coseys don't remember why they're in Bubonic and Tyrannia's yard (they were there as part of a competition to find their neighbors in a mountain of prizes).
Saint Sylvester was renamed Father New Year to avoid religion-based controversy
In The Night of Wishes, there was a character named Saint Sylvester. His animated counterpart was renamed Father New Year. They might have deemed it too dangerous to have a character so obviously based on Pope Sylvester I.- Not true. In the English translation of the book, he was Father New Year, too. If anything, the people who translated the show to English had a copy of the book on hand.
- Wouldn't they know either way the character is Saint Sylvester? Anyway, in the Brazilian translation, he's Saint Sylvester.
- Saint Sylvester is not very well-known in the USA. Presumably the translators of the book thought nobody would understand (in addition to the above possible controversy). This only applies to the book, though.
- In the German (and Hungarian) book, Saint Sylvester says he always comes down to Earth on his name-day, this is why the animals found him at the bells. One, the English-speaking countries don't really have name-days. Two, in German and many other languages, New Year's Eve is called Sylvester. If they had left the name as Saint Sylvester, English-language readers would have been confused why it was exactly him and not some other, better-known saint.
At the end of "Wishful Thinking", Bubonic and Tyrannia still cast the wish spell but Jacob and Maurizio simply wished the spell would fail.
What they did after the day started over wouldn't have necessarily prevented their masters from casting that spell. Tyrannia still could have unwittingly inspired Bubonic.The "Nice Wizards" episode suggests that Mauricio and Jacob would be perfectly capable of casting a spell themselves.
If this is the case, then it would make for an excellent Role Reversal episode, where they steal the halves of a scroll and then use them to cast a spell that would render Metropolis immune to all kinds of magic. Tyrannia and Bubonic would be then forced to somehow undo the spell, possibly getting the riddle from Maledictus Maggot.
