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">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 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 ageway 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 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 Lady and the Tramp before ing 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.
