On Netflix instant streaming, this episode ends when Wanda falls off the bridge which makes the episode incomplete. It is unknown why the rest of the episode was not put in after that scene since some of the other specials are longer than this one. Later on, this was corrected.
Although already seen on the sign of the Camp Learn-a-Torium. In earlier episodes, Flappy Bob takes on a different clown appearance in this film.
After being defeated, Sanderson mutters "Oh, Smoof" which is Norm the Genie says upon being defeated
This is the first time Timmy's romantic "rivals" Tootie and Trixie appear onscreen together, although neither has any dialogue besides Tootie's single spoken musical line.
This is the last time that Flappy Bob's Learn-A-Torium, as well as Happy Peppy Gary and Betty themselves, appear in an episode of The Fairly OddParents mostly because Flappy Bob goes back to being a clown at the end of the episode and the fact that Gary and Betty most likely quit after Timmy and his godparents made the Learn-A-Torium more fun.
In the original story, Flappy Bob was not real, he was just a disguised Imaginary Gary trying to get revenge on Timmy. This is revealed in one of the songs posted on the scribd website under Fred Seibert's portfolio, which posts several of the scripts in their original form.
There are bloopers (in animated form, of course) for this movie/episode.
During the bloopers, the scene where Mark Chang appears, it was the scene for the Pixie Rap part of the Reprise Remix song. Sanderson talked in this scene of the bloopers, but it was in his boring voice of Ben Stein rather than the rapping voice of Redman.
Flappy Bob is said to be 37 years old and that according to this episode, he was born in 1965. This can be a possibility that this episode takes place in 2002, three years before the episode actually airs, and that every episode before "Timmy's Secret Wish!" may take place at this same year.
In the bloopers, it is revealed, that Jorgen has a somewhat British accent after his mouth got caught in a mouse trap.
Mark Chang appears in the bloopers (though the director says he's not in the musical), along with Juandissimo.
This is the only musical episode in the entire series.
HP claims near the end of the episode that when Timmy is 47 years old, he will pay and that their scheme won't fail next time. Though in A Fairly Odd Movie: Grow up, Timmy Turner and A Fairly Odd Christmas, Timmy (who is now played by Drake Bell) is 23 years old. Which means that he has 24 years left before the Pixies can start their scheme.
This episode is dedicated to Ray Charles who died a year before this episode premiered.
This episode lasts 2 days, meaning this is the only episode, as well as the only Nickelodeon special/TV show episode and non-holiday episode, to not air normally nor rarely.
It is unlikely, but, one of Wanda's friends seen at the Fairy World Diner might have been the same one from Dog's Day Afternoon.
The bill presented during the "Get Flappy" song reads the following:
At the beginning of the episode, when a panoramic scene of the broken bridge is shown, there's not a junction neither another track visible near/next to the bridge. But when the train is diverted into another track, a junction with another track magically appear.
The distance between the train and the broken bridge keep changing throughout the beginning.
At the beginning, as the camera zooms in, there's a zooming scene in which the broken bridge is near a field. But in the following scenes, there are not fields nearby.
Flappy Bob is said to be 37 years old and according to the episode, he born in 1965. but this cannot be true, such the episode took place in 2004 which means Flappy Bob should be at least born in 1967, not in 1965.
In the song, Adults Ruin Everything, Timmy says "But I've got two magic fairies!", which means he reveals that he has fairies, but Timmy doesn't lose his fairies when he said that. This may not apply to Da Rules however as Timmy says that line to HP and nobody else besides Timmy, his godparents and HP were there when Timmy says that line.
Timmy's not afraid of Flappy Bob, as he is dressed as a clown, but in another episode, he is afraid of clowns. Timmy may however had conquered his fear of clowns by this point.
