History WesternAnimation / ScoobyDooAndScrappyDoo

* AFoggyDayInLondonTown: "The Night Ghoul of Wonderworld" had the gang go to a robotic amusement park designed after Victorian London. As a result, this trope is there in all its characters-disappearing foggy glory.

* ADogNamedDog: Lampshaded.
-->'''Tessie:''' This is mule. He's a mule.

* BootstrappedTheme: The music during the opening vignette is The New Scooby-Doo Movies and would go on to be reused for the next decade as Scooby's official

-->'''Scrappy:''' That’s the real Blue Scarab! So why is my hero being such a meanie?

* TheDoorSlamsYou: Shaggy and Scooby fall victim to this [[RunningGag a lot.]]
* DramaticUnmask: It was the fourth Scooby series, so this was still in effect.

-->Scrappy: (To Shaggy) The Snake Demon hasn't gotten you yet, has he? (Sounding genuinely quizzical) has he?

-->'''Scrappy:''' Professor Spaulding, eh? I bet that’s an alien!

'''Scrappy:''' Oh, Tick-Tock! Time flies when you’re havin’ fun!

* WakeUpChopSuey: Scrappy, sleeping between Shaggy and Scooby in the sails of a ship the gang's cruising on, hears a foghorn and immediately thinks someone snuck up on him in his sleep, which the two older boys correct him on.

* HunfdredPercentAdorationRating: Scooby has this from Scrappy.

* HundredPercentAdorationRating: Scooby has this from Scrappy.

* DeadpanSnarker: Velma. Shaggy becomes one to Scrappy sometimes as well in this series.

* AFoggyDayInLondonTown: In "The Night Ghoul of Wonderworld" the robotic park is designed after VictorianLondon complete with the mysterious fog that characters disappear into.

* SmarterThenYouLook: Scrappy's not exactly an erudite, as proven by the many times where he activated a trap without making sure that it wasn't Shaggy and Scooby, or when he was convinced that the alien was hiding in a boot that was several times smaller then it. But occasionally he shows glimmers of brilliance, usually when it comes to catching the monster, which he's most interested in.

** Later seasons would show him to be quite smart. Here, he borders on DumbMuscle. Though he does have moments of cleverness. [[NoObjectPermanence (Object permanence forthcoming)]].

* NameAndName

* IJustWantToBeSpecial: [[spoiler:The assistant of the Blue Scarab’s creator was masquerading as The Scarab to get the comic to stop being printed because he was tired of being that “unknown assistant”.]]
* InsaneTrollLogic: Scrappy makes use of this to fit his beliefs that Scooby-Doo is the bravest, most heroic dog ever. In one case when he can't figure out how to make Scooby taking a detour to the kitchen into a monster fighting tactic, he draws the same conclusion anyway.

* ConvienientlyTimedAttackFromBehind: In "The Scarab Lives", Shaggy, Scooby, and Scrappy are ''above'' the other three, though the three manage to launch Scrappy so that he can land ''behind'' the Scarab's head and cover the eyes.

* BearsAreBadNews: In "Hairy Scare from the Devil Bear", if the title didn't tip you off.

* BluntYes:

* BrooklynRage: Scrappy speaks in a very strong Brooklyn accent, which was dropped after this season. {{Justified}} that he grew up in New York.
* BrownNote: Scrappy's "secret whistle" in "Ransom of the Scooby Chief". The only ones who seem to tolerate it are Duke and Annie. It's powerful enough to wreck the windows and tyres of the Mystery Machine. That's powerful lungs for a small dog.

* FurryReminder: Scooby and Scrappy both get this occasionally.
** It's a bit more noticeable with Scrappy, who was the more anthropomorphic of the two. When he got really worked up, he'd start putting barks in mid-sentence, and when the gang was running, he went on all fours.
* TheGlomp: Scrappy gives one to Scooby after they've been reunited in "Ransom of Scooby Chief".

* {{Hammerspace}}: A lot characters make use of this, particularly Scooby and Scrappy.

* PoorlyDisguisedPilot: The last episode introduces Scrappy's old gang in which the main gang takes a seat. It is, in a way, a pilot attempt to where the next series began, and also has a detail that didn't actually lead into a "Scrappy's Gang"–type series.

* RedOniBlueOni: Scrappy's red to Scooby's blue.

* SamusIsAGirl: [[spoiler: Lefty Callahan, who is [[ChekhovsGunman mentioned offhand earlier]] in the episode, is revealed to be a woman.]]

* FanBoy: Scooby, Scrappy, and Shaggy are all huge fans of the superhero ''The Blue Scarab''. They are for once seen gushing over his new comic-book rather than over something edible.

* NoObjectPermanence: Scrappy is under the impression that the human-sized alien can fit in the human-foot sized boot, and seems hilariously bewildered when he's trapped in what he must think is thin-air (actually a clear glass box)

* ShoutOut: A lot in "The Night Ghoul of Wonderland". While there is the direct crossing with ''Literature/SherlockHolmes'', the whole setting of a world where robots allow you to live out a fantasy is a reference to ''Film/{{Westworld}}''. Along the way, the gang does pass by a western-themed area, as well as one like ''Literature/JurassicPark''. This is partly ironic as by this time Creator/MichaelCrichton had written Westworld but had yet written ''Jurassic Park''.
** Not to mention that the host character is clearly made to resemble Mr. Roarke from ''Series/FantasyIsland''.
** In one episode, Shaggy mentions having tickets to a concert by Music/TheBeeGees.

* TastesLikeDiabetes: Scrappy actually tries to avoid this in-universe (and often fails, since lots of the adults find him to be adorable) but he solidly fits into this when he eagerly checks a normal-sized boot for a human-sized alien [[NoObjectPermanence (he'd seen the alien at that point)]] and then falls into it, in his haste. [[TropesAreTools Not that anyone's complaining.]]

--->'''Shaggy:''' Like, hang on, Scrappy!

* DoorSlamsYou: Shaggy and Scooby fall victim to this [[RunningGag a lot.]]

''Scooby-Doo and Scrappy-Doo'' ran from 1979 to 1980. Afterward, it was retooled into a “Three Shorts” format, which carried on for three seasons from 1980 to 1983. The entire season can be found legally by digital download, and was released on DVD in 2015.

* AIIsACrapshoot: Downplayed in "Night Ghoul of Wonder World." The titular Night Ghoul robot is [[spoiler: a malfunctioning dangerous but ultimately mindless automaton at first and then it becomes the disguise for the VillainOfTheWeek]] and as for the Sherlock Holmes robot it is on the hero's side (albeit unable to be much help, being turned to the highest difficulty).

** The MamaBear from "When You Wish upon a Star Creature" counts as well.

* JerkWithAHeartOfGold: Downplayed. Scrappy isn't really a jerk, but rather InnocentlyInsensitive and oblivious to the damage he did on occasion. Nonetheless, he genuinely cares for the others and when he did realize he did damage, he was always regretful and willing to put things to rights. Eventually as he became more aware of his surroudings and others he became just plain NiceGuy.

* SamusIsAGirl: [[spoiler:Lefty Callahan, who is [[ChekhovsGunman mentioned offhand earlier]] in the episode, is revealed to be a woman.]]
* ScarabPower: Used in-universe with ''The Blue Scarab'' as a comic book superhero who seems to be their version of ''Franchise/{{Batman}}'' and who appears in the real world using his intimidation tactics for supervillainy.

** ''The Blue Scarab'' case however stands out as one where the masked figure doesn't pretend to be a ghost and doesn't try to scare anyone away from a place, it is clear that there is a man behind that mask and the question is how much will it drop the popularity of the comic-book he was based on.

* TangledFamilyTree: Scrappy is added as the newest member of the Doo Family. However oddly enough besides this, the rest of the incarnation doesn't introduce any other relatives.
* TastesLikeDiabetes: Scrappy actually tries to avoid this in-universe (and often fails, since lots of the adults find him to be adorable) but he solidly fits into this when he eagerly checks a normal sized boot for a human-sized alien [[NoObjectPermanence (he'd seen the alien at that point)]] and then falls into it, in his haste.
