We see what looked like an old 60s style mansion as music plays in the background. Bats fly by and once they all go past, some white floating text reading "Scooby-Doo! I Choose You!" shows up
We see Scooby against a solid black background, gulping at something we can't see and his eyes go wide.
We see a group of shadows go past an old bookshelf followed by Mystery Inc. walking past the shelf as well.
Once they walk past it, the shelf moves and behind it, a ghost hiding in a secret room looks out and carefully watches the group.
Next thing we see is Daphne standing by an archway in an old castle. Once she starts walking, a cloaked green hand comes out, trying to grab her but fails.
Then we see Fred sitting in a chair, looking over pages from a movie script. When the wall behind him opens up, he falls back into the area behind it. Then, we see Scooby's eyes go wide as his ears wiggle violently out of fear and electricity sparked in-between them. Then, we see Mystery Inc. in a graveyard as a phantom slowly approaches them. Then, we see them booking it down a hallway.r
We see an indian witch doctor, then Shaggy holding Scooby as the two are shaking in a hallway. Then, we see Fred, Velma, Daphne, and Shaggy running down a separate hallway
Then, we see Shaggy skating uncontrollably down a hallway. When he stopped, he had crashed into a bathtub and turned on the connected shower's cold water.
We see Scooby laughing at something, then Velma gasping out of surprise from something we can't see.
Then we see Fred turn his head to the left to look at something, followed by a skull on some books and a blue skull with orange eyes
Next thing we see is Scooby holding Shaggy as they shake in an old living room.
Next thing we see is a glowing ghost of a deep sea diver as it moaned loudly. After that, we see Scooby running along a boardwalk in a barrel as he hit something.
We see Scooby poke his head out of the barrel and look up at what he hit.
We see that Scooby had ran into some creepy looking robot.
Next thing we see is Shaggy against a solid black background as he jumps back and his hair spikes up. We then see Scooby put a finger against his mouth as he goes, "Shh."
We then see a living suit of armor, followed by an ominous pair of eyes, then Scooby jumping out of a pot and running off mid-air.
Next thing we see is Mystery Inc. sitting at a table with Fred, Daphne, Shaggy, and Scooby all looking over Velma's shoulders at the book she was looking through. They all look up as if they got a realization.
After we see the old 60s style mansion and the floating "Scooby-Doo! I Choose You!" letters one more time, we join Scooby in a theme park somewhere
Scooby licks all the cotton candy covering him off slowly and then winks at the audience when he was done.
