Scoob! (2020)

A young, lonely Shaggy Rogers befriends and adopts a young talking stray Great Dane, who he names Scooby-Doo. On Halloween night, Scooby and Shaggy meet three young detectives—Fred Jones, Daphne Blake, and Velma Dinkley—before venturing in a haunted house, where they capture a thief disguised as a ghost, which inspires them to form Mystery Inc. and solve mysteries together. After years of solving mysteries, Mystery Inc. goes into business. During an investor meeting with Simon Cowell, he refuses to do business with Scooby and Shaggy involved. The pair storm out to the Takamoto bowling alley, where they are terrorized by shapeshifting robots called Rottens that belong to Dick Dastardly, who seeks to capture Scooby-Doo and Cerberus’ three skulls.

They are rescued by Dee Dee Skyes, and their lifelong idols, Dynomutt and Brian, who has taken over from his father’s role as the masked superhero Blue Falcon. Dastardly and the Rottens trap and terrorize Scooby and Shaggy in a creepy abandoned amusement park, but they are rescued by the Falcon Force, who investigates that Dastardly finds Scooby important, causing Shaggy to feel alone. Meanwhile, Fred, Daphne, and Velma discover that Dastardly is after Scooby and Shaggy, and head off to investigate. The group also reminisces about the good times they had with Shaggy and Scooby around, before being imprisoned in Dastardly’s airship. They escape with one of the Rottens’ help, and make contact with Dee Dee to explain that she and the others are being taken to Messick Mountain, where the last skull is located.
