* {{Abandonware}}: The game unfortunatly cannot be played on modern systems without an emulator, and even then, the game is notoriously difficult to run.
* AcclaimedFlop: Despite the positive reception the game received at the time, according to [[https://www.google.com/amp/s/jkoseattle.wordpress.com/2011/07/12/nightmare-ned/amp/ Jim Owens]], the songwriter for the game, it didn’t sell very well. Which unfortunately didn’t give Disney much confidence to continue the franchise.
* {{Blooper}}:
** In the School Nightmare, most kids have 5-digit numbers, yet Ned has a ''6-digit'' number, shown to be 777444.
** One kid's photo shows his number to be 77163. When he is seen in person, his number is 77913.
* {{Children Voicing Children}}: Ned's voice actor, Courtland Mead, was around 8-9 years old when voicing Ned, and was the only reoccurring child actor on the cast, everyone else was voiced by adults.
* CowboyBebopAtHisComputer: There is often confusion over whether the TV show or the game came first. For the record, the TV series came first.[[labelnote:Reason]]The creation date for the game's program files is as recent as September 1997, a month after the show ended.[[/labelnote]]
* CreatorCouple: Created by husband and wife team Terry and Sue Shakespeare, who are both the founders of Creative Capers Entertainment.
* DeletedScene: Some scrapped art from the game shows Ned being ferried across what looks like [[ToHellAndBack The river Styx]] by a rotten tooth man from the Medical Nightmare.
* InvisibleAdvertising: Apart from a few print ads in Disney Adventures magazine and previews on VHS, there is little evidence that there was much else in terms of advertising for the game. [[ScrewedbytheNetwork This was even worse in the case of the TV series.]]
* KeepCirculatingTheTapes / ScrewedByTheNetwork: Disney [[OldShame isn't very happy with this series]], apparently. The reruns never went to Creator/ToonDisney, and its theme song wasn't included on the Creator/OneSaturdayMorning soundtrack album.
** For a while, this series was one of the most interesting cases of this trope because, at one point, there were virtually no tapes to circulate. Neither torrents nor decent quality digital episodes existed, and only about 10 poor quality episodes out of 12 had surfaced the internet in over a span of 10 years. It is quite possibly the rarest Disney show in existence.
** As of 2019, all episodes of the show have been found in various qualities and can be viewed on Website/YouTube.
** As of 2022, the show has not been added to Creator/DisneyPlus, and only time will tell if it will ever be added to the streaming platform.
* MeaningfulReleaseDate: The TV show premiered on April 19, 1997, which just so happened to be Courtland Mead’s (Ned's voice actor) tenth birthday.
* RealSongThemeTune: The unreleased version of the "In The Locker" theme, called [[https://www.youtube.com/watch?v=Ct7TW6TE5f0 "The Avenger"]], [[WithLyrics features a few]], [[NightmareFuel new lyrics]]:
-->"The same eyes...\\
''...[-The same eyes!-]''\\
'''''[-- --IT CAN'T BE!--]'''''\\
''...[-The same eyes-]...''"
* StillbornFranchise: With both a video game and a TV show made, it seems Disney really hoped this franchise would take off. Not to mention a lot of passion and effort was put into this project, ESPECIALLY the video game. Unfortunately, it was never able to find the right audience. The fact that it premiered around the time the One Saturday Morning block debuted, with those shows overshadowing it in popularity, didn't help.
* {{Tuckerization}}: Conrad and Vernon (the two bullies) where named after Conrad Vernon (a Storyboard artist who would later be the voice of [[Franchise/{{Shrek}} The Gingerbread Man]])
