History MythologyGag / ScoobyDooMysteryIncorporated

* The revelation that there's always a gang of mystery solvers with a TeamPet that spans back generations, the Scooby gang being the latest one, could be seen as a nod to a period during Hanna-Barbera's history where the company went wild with Scooby-Mania and made several ''Scooby-Doo'' clones like ''WesternAnimation/{{Jabberjaw}}'' or ''WesternAnimation/TheFunkyPhantom''.

* Shaggy and Scooby love watching [[Creator/VincentPrice Vincent]] [[WesternAnimation/The13GhostsOfScoobyDoo Van Ghoul]] movies.
** Van Ghoul is the specter-besieged central figure of episode 19, "Nightfright."

* A Don Knotts caricature can be seen amongst the tourists in episode 1, and he appears again at the beginning of episode 9. Knotts famously guest-starred on ''The New Scooby-Doo Movies''.
* Nugget Nose AKA ''The Galloping Ghost'' (a very obscure 1978 Hanna-Barbera feature from ''Yogi's Space Race'', an equally obscure show) can be seen during the historical montage about Gatorburg.
* Mama Cass Elliot, another ''The New Scooby-Doo Movies'' guest star, is one of the attendees at the auction for a painting. Amazing feat, as she has been dead since 1973.
* In "Secret of the Ghost Rig", while in her bedroom knitting an ascot for Fred, Daphne hums the theme from ''The New Scooby Doo Movies''.
* The haybaler scene from the 1970 episode ''Jeepers, It's The Creeper'' is re-created, save for [[{{Filler}} the baby chick that mistakes Scooby as its mother]].
* The episode 7, "In Fear of the Phantom", The Hex Girls of two Scooby-Doo Movies and ''What's New Scooby-Doo?'' make a reappearance. Not only that, but they sing some of the songs from those appearances.
** Likewise, when they reappear in episode 38, not only are they wearing their original outfits from ''WesternAnimation/ScoobyDooAndTheWitchsGhost'', but they perform "Who Do Voodoo?", which they sang in their second appearance in ''WesternAnimation/ScoobyDooAndTheLegendOfTheVampire''.
* Also in that episode was Harry the ventriloquist's dummy. Shaggy threw his voice a few times in the classic series.
* In episode 8, Velma calls Daphne by her old nickname "Danger-prone Daphne" after she falls into the hidden door inside a tree.

* In a web game tie-in, one sidequest has Shaggy and Scooby collecting scattered pages of a play script. Shaggy notes that the play's set in a town called "Coolsville" (from ''A Pup Named Scooby-Doo'' and the live-action movies) and the main suspect is named Red Herring (also from ''Pup'').
* Suzie Chan, from ''WesternAnimation/TheAmazingChanAndTheChanClan'', appears in episodes 6 and 16.
** A poster of her and Stanley can be seen on HP Hatecraft's wall in episode 25.

* The Monster Museum in the beginning of Episode 20 sees a statue of [[WesternAnimation/The13GhostsOfScoobyDoo Flim-Flam]] (who Daphne described as getting 25-to-life, despite being a pre-teen con artist), and when she sees a statue of ''Scrappy Doo'':
---> '''Daphne:''' Wow! I haven't seen--
---> '''Fred:''' Look away, Daphne! [[TakeThatScrappy We all promised each other that we would never speak of it. Not ever!]]
* Episode 21: Linda Cardellini, [[Film/ScoobyDoo Velma]] from the live-action theatrical Scooby Doo movies, is the voice of Hot Dog Water. That makes two members of that cast giving voices to this animated edition.
* The high-tech costume and superweaponry [[spoiler: Alice May]] used in her Oblivia the Obliteratrix disguise were supplied to her by a man on Destroido's payroll: [[WesternAnimation/JonnyQuest Benton Quest]].
* The pose for the yearbook photo of the original Mystery Inc is similar to a pose that Scooby's Mystery Inc had in ''Scooby Doo, Where Are You?'' theme song.
** The current-day Mystery Inc also strikes that pose at one point.

* Episode 37: The seal named Scooby was seen eating a box of snacks with Scooby written on it. Also, he and his friends are from the ''Moby Dick'' segments of the Hanna-Barbera cartoon ''Moby Dick and Mighty Mightor'', and their fathers are from the Hanna-Barbera cartoon ''Sealab 2020''.
* Episode 39: Charlie The Robot from the original ''Scooby-Doo, Where Are You!'' cartoon plays a key role in the mystery.
* In "Heart of Evil" there is a Scooby Snacks box on the table. Also, when Scooby and Dynomutt meet, their high-five routine is exactly the same as Scooby and Scooby Dum in the opening sequence of ''The Scooby Doo Show'' (which was the other half of ''The Scooby-Doo/Dynomutt Hour'').
* The Final Episode where the gang decide to head out to the other side of the country via roadtrip and solve every mystery they come across along the way. Pretty much a reference to the original series.
** The scene where they are watching the new Mr. E's message, the group are positioned and posed around Velma's laptop in the exact same way as the scene from the first episode (also featured in the theme song) where the gang are researching the magnifying glasses clue (with the book replaced with her laptop).

* Velma's mother is wearing an unused Alex Toth design for Velma's outfit in the original ''Scooby Doo'' cartoon.

* The Spanish conquistadors whose ghosts appear repeatedly as the series builds to its conclusion have a ''lot'' in common with Morgan Moonscar and his pirates from ''WesternAnimation/ScoobyDooOnZombieIsland'': both groups had been ruthless pillagers in life, who fell afoul of genuine evil magic and were denied the opportunity to rest in peace in death; both also did their best to warn the Scooby gang of danger and to arrange for the evil they'd contributed to unleashing to ultimately be put to right. Oh, and both played a key PosthumousCharacter role in groundbreaking ''Scooby-Doo'' installments that took the franchise along ''much'' darker and more mature path than ever before.

*** Van Ghoul is the specter-besieged central figure of episode 19, "Nightfright."
** Velma's parents run a supernatural tour of the city, which references many ghosts from the original series, such as The Miner 49'er. When Velma's forced to work as a tour guide, she takes great pleasure in explaining to the gaping tourists just how fake each and every one of them were.
