Scoob!, the latest feature film in the Scooby-Doo franchise, is packed full of Easter eggs making reference to other classic Hanna-Barbera characters. There are also a number of tributes to the creators and actors behind the original Scooby-Doo cartoons. Scoob! released via VOD May 14, 2020.

First airing in the fall of 1969, Scooby-Doo, Where Are You? was made in direct response to complaints from parents groups that most of Hanna-Barbera's cartoons at the time were too violent for children. Taking inspiration from Archie Comics and The Many Loves of Dobie Gillis, the studio worked with CBS executive Fred Silverman to make a show about a group of teenage detectives with a talking dog sidekick. The show proved to be a huge success and ran for decades on Saturday mornings throughout the 1970s and 1980s, inspiring numerous imitators with the same formula.

The story of Scoob! utilizes characters from not only the Scooby-Doo cartoons, but also from Wacky Races, Captain Caveman and the Teen Angels and Dynomutt, Dog Wonder. Yet, the movie drops hints regarding characters from other Hanna-Barbera shows, suggesting a larger shared universe. It remains to be seen, however, if Scoob! will prove successful enough to merit sequels expanding this reality, in the same way that Iron-Man led to the creation of the Marvel Cinematic Universe.

A Pup Named Scooby-Doo

Young Shaggy and Scooby-Doo in SCOOB

The opening scenes of Scoob! show how Shaggy and Scooby met on the streets of Venice Beach, California. The two became best friends after Shaggy rescued a very hungry stray, giving him the name Scooby-Doo (after his favorite brand of snacks) and a collar with his initials on them. The design for the young Scooby is taken directly from the 1988 animated series A Pup Named Scooby-Doo, which showcased the adventures of the Mysteries Inc. gang when they were still in elementary school.

Casey's Creations

Scoob! Shaggy and Casey's Creations

When Shaggy first appears in Scoob!, he's just had his snack knocked out of his hands by the police officer chasing Scooby-Doo. Later, the restaurant Shaggy was leaving is revealed as Casey's Creations, which sells both donuts and turkey drumsticks, along with pizza, hot dogs, pretzels and ice cream based on their psychedelic sign. Apart from being a nod to Shaggy's love of junk food, the restaurant also seems to be a nod to Casey Kasem; the American Top 40 DJ who voiced Shaggy from 1967 to 1997 and again from 2002 to 2009. This break came after Kasem, a devout vegan, refused to voice Shaggy for a Burger King commercial, but he returned to the role after it was agreed that his Shaggy would be portrayed as a vegetarian. Kasem was also the voice of Robin on Super Friends.

The Classic "Scooby-Doo, Where Are You?" Introduction

Scoob! Opening Montage Scooby Doo Where Are You Tribute

After solving their first case in Scoob! as kids, the Mysteries Inc. gang age into young adulthood through a musical montage. This montage is set to the theme of the original Scooby-Doo, Where Are You? show, with the characters subtly aging through a shot-by-shot recreation of the show's introduction, complete with Fred accidentally triggering a secret passageway by leaning back in a chair and Scooby and Shaggy losing their balance while roller-skating and crashing into some garbage cans.

The New Scooby-Doo Movies

Scoob! Simon Cowell with Velma, Daphne and Fred

Originally running for two seasons on CBS in 1972, The New Scooby-Doo Movies partnered up the Mysteries Inc. gang with various celebrity guests including The Harlem Globetrotters and Sonny and Cher, along with other Hanna-Barbera animated characters, such as Josie and the Pussycats and Speed Buggy. While the celebrity guests were famous for their time, the cameos by actors like Phyllis Diller and Don Knotts became increasingly dated as the show continued to see airplay in syndicated reruns and many of the kids who grew up watching Scooby-Doo had no idea who any of these people were. Scoob! offers up an ironic nod to this trend, with former American Idol judge Simon Cowell (playing himself) being revealed as the mystery investor who wants to help the Mysteries Inc. gang form an actual business based around their amateur sleuthing.

Takamoto Bowl

Scoob! Takamoto Bowl

After Simon Cowell dismisses Scooby and Shaggy's contributions to Mysteries Inc. as unimportant, they storm off to stress eat and bowl at Takamoto Bowl; Venice Beach's only bowling alley/Japanese restaurant. The establishment is named in honor of Iwao Takamoto; a legendary animator who started working for Walt Disney Animation Studios in 1945, contributing to films like Cinderella and Lady and the Tramp before joining Hanna-Barbera Productions in 1961. It was here that he designed many classic cartoon characters, including Scooby-Doo, whom he modeled on a co-worker's Great Dane.

The (Really) Rottens

Scoob! The Rottens

Dick Dastardly deploys an army of robot drones collectively known as the Rottens to kidnap Scooby-Doo and Shaggy. While the Rottens' default mode is surprisingly cute (and invite comparison to the Minions from Despicable Me), they are capable of shifting into a scorpion-like battle-mode, as well as disguising themselves as bowling balls and bowling pins. The Rottens seem to be named in honor of the Really Rottens, the evil team of cheaters from the series Laff-A-Lypmics.

Dee Dee Skyes

Scoob! Dee Dee Skyes

Shortly after being rescued from the Rottens, Scooby and Shaggy meet Dee Dee Skyes; pilot of the Falcon Fury and one of Blue Falcon's field assistants. Dee Dee Skyes first appeared in the 1977 animated series Captain Caveman and the Teen Angels, which was created to capitalize on the popularity of Charlie's Angels. Dee Dee was the leader of the Teen Angels; a group of mystery solving teenage girls in the same vein as Mysteries Inc. who discovered Captain Caveman frozen in a block of ice and thawed him out to help them in crime-fighting. The other two Teen Angels, Taffy and Brenda, don't appear in Scoob! but there's a chance they could be working in the background of the Falcon Fury, along with the heard-but-never seen Keith.

Blue Falcon and Dynomutt

Scoob! Blue Falcon and Dyno-Mutt

First appearing in The Scooby-Doo/Dynomutt Hour in 1976, millionaire socialite Radley Crown used his fortune to fight crime as Blue Falcon, with the limited assistance of his bumbling robot dog, Dynomutt. This dynamic is reversed in Scoob! with Dynomutt now a hardened veteran crime-fighter babysitting Brian Crown, the eldest son of the original Blue Falcon, who has assumed his father's mantle despite being better suited to spinning records as a DJ than fighting crime.

Wacky Races

Scoob! Dick Dastardly

With a name like Richard Millhouse Dastardly, it seems that Dick Dastardly was doomed to a life of villainy. A look at his police record in Scoob! reveals that he's wanted around the world for crimes raging from flying without a pilot's licence and tripping old ladies to stealing historical artifacts and buying black market car parts. This last crime seems to be a nod to where Dastardly first appeared in the 1968 cartoon Wacky Races. The reference to his not having a pilot's license is likely a nod to Dastardly's role as the leader of a villainous squadron of pilots in 1969's Dastardly & Muttley in Their Flying Machines.

Peebles Pet Shop

Scoob! Peebles Pet Shop

As Velma, Daphne and Fred track the missing Scooby and Shaggy to the Takamoto Bowl, another business is visible next-door to the bowling alley/Japanese restaurant; Peebles Pet Shop. Hanna-Barbera fans will recognize this as the setting of The Magilla Gorilla Show, where the kindly yet put-upon Mr. Peebles was desperate to sell Magilla Gorilla before the pun-loving primate ate him into bankruptcy. Every episode featured someone wanting to adopt Magilla, only for him to be returned for a refund by the episode's end. Judging by Magilla's absence from the shop window, it would appear that he's currently out with another new owner.

Dastardly & Muttley in Their Flying Machines

Muttley in Scoob!

They say that even bad men love their mothers and their dogs. While the former statement can't be proven in Dick Dastardly's case, he certainly misses his partner in crime and best friend Muttley, though he'll deny it to his dying breath. It is revealed over the course of Scoob! that Dastardly built a small shrine to his canine cohort and he keeps a picture of Muttley, proudly displaying a chest full of medals, in his workshop. This in itself is a nod to Dastardly & Muttley in Their Flying Machines, where Muttley was frequently called upon to save Dastardly but would only do it for the promise of a medal.

Squiddly Diddly

Scoob! Squiddly Diddly

As Fred, Daphne and Velma search for Shaggy and Scooby, they pass a billboard advertising a theme-park called Bubbleland, with a cartoonish octopus saying he can be seen there. The octopus is Squiddly Diddly, who appeared on The Atom Ant/Secret Squirrel Show in 1965. Squiddley was a musician who performed in his own tank in Bubbleland, but dreamed of making it big on his own in the outside world. Most of his adventures saw him either trying to escape from Bubbleland or working with the park's manager, Chief Winchle, to solve various problems that threatened to close the park.

Hong Kong Phooey

Hong Kong Phooey Scoob!

Created in 1974 in response to the popularity of kung-fu action movies, Hong Kong Phooey centered upon the adventures of a canine vigilante who tried to protect his city with his martial arts mastery.  Of course his feline sidekick Spot did most of the work, but "the great Hong Kong Phooey" always got the credit. The "number one super-guy" can be seen on the side of a cabinet for a game called Phooey Phighter when Scooby and Shaggy take refugee in an abandoned amusement park's arcade while outrunning Dastardly and the Rottens.

The Banana Splits' Adventure Hour

Scoob! Banana Splits

Produced in 1968 in conjunction with Sid and Marty Kroft, The Bananas Splits' Adventure Hour was one of Hanna-Barbera's few attempts at live-action programming. The show centered around the titular band and mixed their live-action adventures with various animated shorts. A concert poster promoting the Banana Splits can be seen on the wall of the arcade that Scooby and Shaggy barricade themselves in while escaping from Dick Dastardly and the Rottens. This is a far better tribute to the classic kids' show than the 2019 horror movie The Banana Splits, featuring murderous robot versions of Fleegle, Bingo, Drooper and Snorky.

The Hex Girls

Scoob! Hex Girls

First appearing in the 1999 direct-to-video animated film Scooby-Doo and the Witch's Ghost, The Hex Girls are a trio of eco-goth rock stars who befriended the Mysteries Inc. gang while they were investigating rumors of dark magic in Oakhaven, Massachusetts.  The Hex Girls proved popular enough to appear in later Scooby-Doo movies and animated series and merited two Easter eggs in the arcade chase sequence. A Hex Girls concert poster can be seen immediately to the right of the arcade entrance and there's a Hex Girls pinball game among the various pinball machines on the right wall.

Laff-A-Lympics

Scoob! Laff-A-Lympics

One of the arcade games Shaggy and Scooby use to make their barricade is called Laff-A-Lympians. This is a nod to the 1977 animated series Scooby's All-Star Laff-a-Lympics, which saw three teams of Hanna-Barbera's characters competing in various challenges loosely based on the Olympic Games. Scooby and Shaggy were the captains of one team, The Scooby-Doobies, which was composed of various characters from Hanna-Barbera's many detective shows centering around talking animals and their human companions.

Space Stars

Space Stars Scoob!

Space Stars was a short-lived science-fiction anthology series, which ran for one season in 1981. The show featured new adventures starring the classic Hanna-Barbera action heroes Space Ghost and The Herculoids, plus two new series; Space-Ace and the Space-Mutts and Teen Force. A Space Stars arcade game is among the cabinets Shaggy and Scooby use to block the arcade entrance while running away from Dick Dastardly.

The Perils Of Penelope Pitstop

Scoob! Penelope Pitstop

First appearing in Wacky Races along with Dick Dastardly and Muttley, Penelope Pitstop was the only woman to compete in the crazed competition. A Southern Belle and proper lady through and through, she was not above playing on the chivalric impulses of her male opponents to get ahead. She would later star in her own spin-off series, The Perils of Penelope Pitstop. An arcade cabinet for a racing game featuring her trademark PP heart logo can be seen in the arcade chase scene.

Frankenstein, Jr. and The Impossibles

Scoob! Frankenstein Jr. and The Impossibles

Running for two seasons in 1966, Frankenstein, Jr. and The Impossibles presented short cartoons featuring two drastically different superhero teams. Frankenstein, Jr. was a 30-foot-high, crime-fighting robot, resembling the classic cinematic appearance of Frankenstein's Monster, controlled by young Buzz Conroy Jr., who built the robot with his dad, Dr. Buzz Conroy. The Impossibles were a trio of rock stars who lived a secret life as the superheroes Fluid Man, Coil Man and Multi Man. The Impossibles appear on a pinball machine next to the Hex Girls' game and Frankenstein, Jr. appears on a cabinet in the back of the arcade.

Jellystone National Park

Scoob! Jellystone National Park

Another billboard visible as Fred, Daphne and Velma go on the hunt for Shaggy and Scooby advertises Jellystone National Park as a vacation destination. This is the home of Yogi Bear, the famed "pic-a-nic basket" thief and bane of Ranger Smith's existence. Yogi had a solo film in 2010 which was a notorious bomb. Perhaps this Easter egg is a sign that Yogi will be making a comeback in the not-too-distant future?

Messick Mountain

Scoob! Messick Mountain

The third Skull of Cerberus, which Dick Dastardly needs to open a portal to the underworld, is located near a peak called Messick Mountain. This landmark is a tribute to voice actor Don Messick, who was the original voice of Scooby Doo until his death in 1997. Messick was also the voice of many other Hanna-Barbera characters, including Boo-Boo Bear and Ranger Smith on Yogi Bear, Papa Smurf on The Smurfs and Dr. Benton Quest on Jonny Quest.

Captain Caveman

Scoob! Captain Caverman

The star of Captain Caveman and the Teen Angels, Captain Caveman has a radically different origin story in the the world of Scoob! Rather than being the worlds' first superhero, he's the protector of a community of cave people living in a subterranean lost world under Messick Mountain. With dinosaurs and cave-people living alongside one another, Captain Caveman's homeland is similar to the Savage Land from Marvel Comics. Based on the closing credits, Captain Caveman made his way to the surface world and joined Falcon Force.

The Flintstones

Scoob! Caveman Uses Turtle as Trumpet

While the first family of Bedrock doesn't make an appearance in Scoob! there are two shout-outs to The Flintstones during the Messick Mountain sequence. First, Captain Caveman refers to the final Skull of Cerberus as a sacred artifact his people call "The Slaghoople." Slaghoople was the maiden name of Wilma Flintstone before she got married to Fred Flintstone. Later, when Captain Caveman challenges Blue Falcon and Scooby-Doo in ritual combat for ownership of the Skull of Cerberus, the signal for the fight to begin starts with a turtle being used as a horn. The noise produced is the same whistle which announced when it was time for Fred to get off work in The Flintstones' opening theme.
