* {{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...
* MagnumOpus: Combining music, puppetry, ethos, on an international level from the very start.
* NightmareFuel: The Terrible Tunnel. "Heidi!" ''"HOOOOOO-oooo...."''
* PeripheryDemographic: Indeed, many are the fans who like it even more as adults.
* {{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.
