History WesternAnimation / ScoobyDooAndScrappyDoo

The year was 1979. The old Franchise/ScoobyDoo formula was getting old, and [[Creator/AmericanBroadcastingCompany ABC]] was looking into other shows to fill in its slot instead. But...Creator/HannaBarbera had one last trick up their sleeves. So, maybe for worse, maybe for better...they introduced Scooby's nephew, Scrappy-Doo, to the formula.

** Annie of Shaggy and Daphne, being the DistressedDamsel and relying on Duke and Scrappy to figure things out, and being rather cautious when it comes to the kidnappers.

* ThreeAmigos: Scrappy, Duke, and Annie in the season finale.

* PlayAlongPrisoner: The climax of Ransom of Scooby Chief, where the kidnappers sneak up behind Scrappy and his friends and toss a net over them. There's nothing about the net that particularly stops the puppies from crawling under it, (and they don't even put up any struggle, they just seem surprised and annoyed). But Scrappy decides to be still a moment and put faith in Scooby, which the older Doo delivers when they crash into the kidnappers. Immediately afterwards the pups are seen without the net cheering, implying they took it off right as soon as the kidnappers were taken out.

* AmbiguousDisorder: Scrappy's poor social skills despite being friendly and outgoing and his sometimes strange perception of what goes around him are both associated with the autism spectrum.

* 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. [[Administrivia/TropesAreTools Not that anyone's complaining.]]

* ConveyorBeltODoom: Scooby, Scrappy, and Shaggy nearly fall victim to this ''twice'': the first time at a newspaper printing factory in "The Scarab Lives!" and the second at a sawmill in "A Gem of a Case".

* ConveyorBeltODoom: Scooby, Scrappy, and Shaggy nearly fall victim to this in "The Scarab Lives!"

* OutOfFocus: Fred, Velma, and Daphne struggled to compete with Scrappy's stronger characterization, though writers did try to save them once the new character's presence shed light on it. However, they ultimately were removed by the next season.

* SamusIsAGirl: In "I Left My Neck In San Fransisco", Lefty Callahan, who is mentioned offhand earlier in the episode, is revealed to be a woman

* HundredPercentAdorationRating: Scooby has this from Scrappy.

* AdultFear: Scrappy often creates this for Scooby and Shaggy, regardless of what he does.
** Though everyone has a MassOhCrap when Scrappy, after being hauled up on the boat's anchor, takes the anchor and himself overboard dives overboard to look for Daphne's lost her snake demon idol (courtesy of a snake demon); the idol is forgotten about until the Snake Demon brings it back onto the ship in favor of bringing Scrappy back up.
-->'''Velma:''' (Frightened) Pull faster!

* BootstrappedTheme: The music during the opening vignette is ''WesternAnimation/TheNew ScoobyDooMovies'' and would go on to be reused for the next decade as Scooby's official
