Synopsis
At Venice Beach, California, an unmanned, stray puppy is wandering the streets looking for food. He comes across a restaurant, Alexander's Great Gyros, and sees a giant piece of meat hanging in the window. Seeing as how the meat was unclaimed, the puppy thinks nothing of picking it up and stealing it.

The shop owner calls out as his meat is being stolen and a cop starts pursuing the puppy. In the midst of the pursuit, the puppy bumps into a young boy, Shaggy Rogers, who is walking by himself to the beach. However, the puppy keeps on running away from the cop, paying little regard to Shaggy.

Shaggy plugs in earbuds and begins listening to music on his phone. The song he is listening to is about loneliness, so he changes the music station. The next song is also about loneliness, so he changes the music station again. This continues on for a few songs until he gives up and begins listening to a podcast, only to find out that it is about loneliness.

After a long chase, the puppy eventually escapes the cop by hiding behind two mounds of sand. Shaggy then comes up to the mounds of sand, unaware of the puppy's presence, and sets up a picnic, pretending that the mounds of sand were his friends.

The puppy overhears and starts to feel empathetic towards Shaggy and comes out from behind the sand, offering to eat with Shaggy. When Shaggy explains that while he has a sandwich to share but that it doesn't contain any meat, the puppy brings out the stolen piece of gyro meat and cuts slices for the sandwich.

The cop finally finds Shaggy and the puppy and insists that "this mangy stray is coming with me." Shaggy refuses and claims that the puppy is his dog and that his name is Snacks. When the cop doesn't believe the name, Shaggy corrects himself and says that his name is Scooby-Dooby-Doo. The cop then lets them be, as the law is that dogs with middle names can't be arrested. Shaggy tells the puppy, now named Scooby, that he can be his dog if he liked. Scooby agrees and they head home to Shaggy's house.

Once at home, Shaggy shows Scooby his room, which is filled with memorabilia of Blue Falcon and Dynomutt, Shaggy's favorite superheroes. Shaggy then gives Scooby a gift, a custom collar for him, which Scooby swears to never take off. While hugging, Shaggy then promises Scooby that he would never leave him no matter what.

On Halloween night, Shaggy and Scooby, dressed up as Blue Falcon and Dynomutt, go trick-or-treating with Wally Rogers (Shaggy's cousin), his pet silver Great Dane/Dalmatian dog Ruffy-Doo (Scooby's cousin), and Scooby's childhood friends Tom Cat and Jerry Mouse. They come to the Rigby House, a mansion that Tom claims is haunted. They begin to walk away when three bullies, led by the neighborhood bully Red Herring, steal Shaggy and Scooby's bag of candy and throw it into the Rigby House until a boy, who turns out to be a huge rival of Red, defends the group by beating up the bullies. After the bullies run away, the six friends meet Fred Jones and his fraternal twin brother Riff, Daphne Blake and her fraternal twin sister Bridget, and Velma Dinkley and her little sister Madelyn, a group of friends, who want to make sure they're okay after being picked on. They offer to go into the house and try to get their candy back.

When they walk into the house they are attacked by a ghost who chases them around. During the commotion, Velma notices that the ghost is attached to a moving wire system in the ceiling. Fred cuts the wire with an ax that was hanging on the wall and the ghost falls down, only to be tied up by Daphne and Velma, and attacked by Fred.

Upon looking more carefully at the ghost they discover that he isn't a ghost and is actually Mr. Rigby, wearing a mask. Shaggy and Scooby discover a secret hidden room, filled to the brim with expensive, stolen electronics. The police arrive and take away Mr. Rigby. The twelve friends, happy with their success in stopping a crime decide to pursue mystery solving.
