The [=Trap Door=] was a British {{Claymation}} show that first aired in 1984. The show was set in a {{Haunted Castle}} owned by an unseen creature known only as 'The Thing Upstairs'. The main character was this creature's servant, a blue blob named Berk, who lived in the castle's lower floors along with his friends, a skull named Boni and a strange spider-like creature named Drutt. In every episode, the titular [=trap door=] would open, and a monster would come out, usually to hinder Berk in his toils. Each episode lasted around five minutes.

!!Provides Examples Of:

* AllJustADream: 'Don't Let the Bed Bugs Bite' and 'Moany Boni'
* BattleDiscretionShot: More often than not, violence occurs in another room, complete with ScreenShake.
* BedsheetGhost: Berk gets haunted by loads of these in 'Boo!'
* BolivianArmyEnding: [[spoiler: The last episode of the series has the Big Red Thing, one of the nastiest creatures to come through the trap door, jump out and attack Berk and his friends only for the show to cut out]]
* ByTheLightsOfTheirEyes
* CatchPhrase: "Oh Globbits!"
** "It's bonking time!"
* CatScare: Done with Drutt in the middle of a chase scene.
* ChewToy: Boni. "I think I feel a headache coming on". Berk gets it pretty bad at times as well.
* TheComicallySerious: Boni, though usually much more level headed (no pun intended) than Berk, is very neurotic and occasionally prone to [[NotSoAboveItAll bursts of childish excitment]].
* CordonBleughChef: Berk often cooks with such ingredients as live worms and eyeballs. Justified, since he's cooking for a monster. Taken to extremes in the first episode when a yellow monster emerges from the trap door and eats Berk's carefully prepared dinner. Berk improvises and serves Yellow Monster Surprise instead. The thing congratulated him on the texture.
* CousinOliver: Drutt had babies that became regular characters.
* CrossdressingVoices: Drutt... maybe.
* CrouchingMoronHiddenBadass: A good few of the monsters actually find out the hard way not to mess with Berk. Rogg also deals with some rather swiftly.
** In the episode "The Midnight Snack" he actually won a 4-on-1 fight. Pretty impressive
* DeadpanSnarker: Boni. Berk, too, at times.
* DefangedHorrors: Some monsters, like Rogg, can be quite nice.
* DemBones: Boni
* DerangedAnimation
* TheDitz: Rogg.
-->'''Berk:''' You got any bright ideas, then?
-->'''Rogg:''' Well, you could um... er... don't know.
-->'''Berk:''' [''[[NoFourthWall addressing the audience]]''] The sad thing is, that you've just heard the brightest idea Rogg's ever had. Ever.
** Berk leans lightly into one at times. He has moments of inspiration, but is a fairly careless guy.
* DramaticThunder: OncePerEpisode.
* EarlyBirdCameo: A few monsters, such as The Splund, cameo in the episode "Don't Open That Trap Door", before getting their own spotlight episode.
* EldritchAbomination: 'Im Upstairs is implied to be this.
** He is (perhaps) seen in one episode. He is, indeed, a EldritchAbomination.
* ExtraEyes: Some of the trap door monsters. 'Im Upstairs, too, from what we hear. They even come out.
** EyeSpy: The Thing's eyes still function when they're detached.
--->'''Berk:''' [[OhCrap Oh, globbits.]] I hates eyeballs.
* GettingCrapPastTheRadar: Drutt. See Sdrawkcab Name below.
** "Berk" is cockney for a female body part and he repeatedly expresses a fondness for bonking things.
*** It's also a same for a silly person. Seems apt.
* GrotesqueCute: A cute little monster opens his mouth to reveal rows of jagged fangs.
* GrumpyBear: Boni.
* [[GuardingThePortal Guarding The Trap Door]]: Even though Berk often leaves it ajar.
* HeroicSacrifice: [[spoiler: Rogg, in the final episode. [[DisneyDeath He gets better]].]]
* ItsAlwaysSpring: Or It's Always a Dark Stormy Night.
* KindheartedSimpleton: Rogg is one of the friendlier creatures to come out of the trap door. It may come from the fact he is a complete ditz.
* MeaningfulName: Berk is British slang for a stupid, often easy to manipulate person.
* MonsterOfTheWeek: LOTS of this.
* MusicalEpisode: An entire episode was dedicated to [[ThemeTuneExtended an extended version of the theme tune]]. Aptly named [[http://www.youtube.com/watch?v=ldlCD7GR2JI Don't You Open That Trap Door]], which is the first lyric of the theme song.
* MusicSoothesTheSavageBeast: Subverted in ''Don't You Open That Trap Door,'' Bert turns on the radio, leading nearly every monster from the series to pop up and run rampant in the kitchen. They scurry back in when I'm Upstairs bellows about the noise.
* NightmareSequence: 'Don't Let the Bed Bugs Bite'
* NoFourthWall: Berk often addresses the kids directly. Boni sometimes explains what's going on at an episode's beginning, Series/AlloAllo style.
* OncePerEpisode: The Trap Door unleashes a fearsome monster.
** {{Lampshaded}} in "The Dose":
--->'''Boni:''' Guess what's going to happen ''next''.
--->''[The Trap Door opens and a green monster slithers out.]''
--->'''Boni:''' ''[smugly]'' [[IWarnedYou What did I say?]]
* OnlySaneMan: Boni.
* PowerTrio:

* PardonMyKlingon: 'Globbits!' 'Great Grumfuttoks Tusks!'
* RecurringCharacter: Rogg, Bubo, the Big Red Thing
* ScrewThisImOuttaHere: [[spoiler: Berk, in the Season 1 Finale.]]
* ScrewySquirrel: A fair few of the monsters from the trap door are more trouble makers or pranksters than outright menaces. Bubo is perhaps the most notable.

* VitriolicBestBuds: Berk and Boni. Berk also ends up one to the obliviously friendly Rogg, though seems to lighten up by Season Two.
** Point in case:
--->'''Rogg:''' ''[To the audience]'' I like Berk. He's my friend.
--->'''Berk:''' I hate you!
* YourTomcatIsPregnant / MisterSeahorse: Drutt has babies. They still refer to him/her with male pronouns.
