* {{Anvilicious}}: One of the all-too-rare successful aversions!
* EarWorm: The theme song... oh god THE THEME SONG!

* FridgeHorror: In "Marooned", Red and Boober are trapped in a cave-in and running out of air. They both quickly ''recognize the symptoms'' of this. Suddenly, living underground doesn't seem quite so charming and carefree...
* FridgeLogic: The intro features more than one Mokey. The second verse of the theme song (the "doozer verse") features the Doozers singing and working while Mokey sits in the background watching them. Then the core five pops up to finish the verse. Mokey is, of course one of them, while ''another Mokey'' is still visible in the background. Technicalities aside (more than one muppet), how did she manage to be two places at once?
* {{Moe}}: Wembley. The other four main characters have their moments as well.
* NightmareFuel: The Terrible Tunnel. "Heidi!" ''"HOOOOOO-oooo.
** The Gorgs, to many a younger viewer. It doesn't help that one of them (Junior) grabs Gobo in the opening theme.
** In "Marooned", Boober and Red get trapped in a rock slide. As the ceiling was slowly collapsing and threatening to crush them to death, the terrified Fraggles tried to imagine what happens after they die. Not a good episode for the claustrophobic. The place they're trapped under has an ominous red glow around them making it look like they're in Hell! Even worse, it's also Boober's birthday they were about to get crushed on Boober's birthday! Death is one thing nobody wants on their birthday!
* {{Padding}}: When Creator/ABCFamily ran the ChristmasEpisode in 2015, they extended it to 45 minutes(!) and filled the remaining space with extra commercials.
* PeripheryDemographic: Indeed, many are the fans who like it even more as adults.
* SpecialEffectFailure: In "We Love You Wembley" there is a scene in the Gorgs' garden where Junior runs toward Mokey and Wembley. The camera moves a little to the right but the Fraggles (who were filmed separately via bluescreen) stay in place perfectly. Especially jarring since the bluescreening in the rest of the series was impressive for its day.
* {{Wangst}}: Gobo occasionally falls into this, mostly based on his status of de-facto leader of the gang. As early as the first season, he spends most of the Invisible Garboil episode in the depths of a HeroicBSOD!
** This is even parodied in the second-season episode "Wembley and the Great Race", where Wembley has a DreamSequence in which Gobo goes completely to pieces over losing a race.
* TheWoobie: All the main Fraggles have at least one Woobieish moment throughout the show.
