Corrected entry: When the monsters appear in the lobby and Shaggy yells, " Scooby Doo, where are you?", before Shaggy yells that, you can see Shaggy look at his mark of where to stop running.
Corrected entry: Near the end, where the reporters are all gathering around the gang as they exit the park, the reporter on the viewer's right is asking a question, while the reporter besider her, in the green, is mouthing the words at the same time.
Corrected entry: When Fred is saying that there is no such thing as monsters, and the monster comes in through the glass, when Fred jumps you can see that he looks straight at the camera when he lands.
Corrected entry: The unstable protoplasm in the presence of the Daemon Ritus causes them to randomly change bodies until the protoplasm realigns with the appropriate body. Velma's and Shaggy's protoplasm were already in the appropriate bodies so they should be stable and would not change bodies. Only Daphne's and Fred's protoplasm were supposed to be unstable and switch bodies.
Corrected entry: In the end of the movie when Shaggy opens the hole to let out Emile Mondavarious, Emile says, "About two years ago." But he couldn't be in there for two years without food or water because he would die after three days because of lack of water.
Corrected entry: When the gang are in the woods and their protoplasms are changing bodies, Shaggy (as Fred) points to Velma and asks her what's going on, but shouldn't he have pointed at Fred since Fred has Velma's protoplasm in him?
Corrected entry: In the spooky castle on the roller coaster ride, Daphne is about 4 metres away from the swords. It cuts to Fred and Velma at the bookcase, trying to find the secret passage. Velma throws a book to Fred to protect him from the swinging blades. The impact forces him back, and thus turning off the ride. In the time that this happened, Daphne would have already hit the sword blades.
Corrected entry: When Daphne, Mary Jane, Shaggy and Scooby are on the pier waiting for the life guard, a volley ball rolls to Daphne and wakes her and the rest of them up. You see that the ball rolls of the picture and not at Daphene's feet. When she throws the ball back, she picks it up at her feet.
Corrected entry: When Daphne's protoplasma went into Fred, he was wearing a no sleeve white shirt with shorts. A few minutes later when everyone meets in the woods, he is wearing a blue shirt and jeans and carrying Daphne's purse. When did he have time to change? Everyone else is still wearing the same clothes.
Corrected entry: In the bar scene, just after Velma tells the gang's story to the man, we can see that she is dead drunk. Her glasses are askew and her hair is ruffled. Moments later, a monster snatches her up and she is sober, composed, and thinking .
Corrected entry: When you see the plane you see MaryJane sitting wearing a blue shirt but when you see her walking in she has on a pink shirt.
Corrected entry: In the deleted scenes on the DVD, there is a scene where Daphne is showing her new martial arts moves. When she gets stuck in a tree, you can very visibly see the wire that's holding her up.
Corrected entry: When the group is about to go save Scooby, Velma is wearing the rather revealing sweater, and Daphne is wearing her minidress. When they are setting up the disco skull, Velma is wearing her turtleneck (which we later find on her boyfriend), and Daphne is wearing a pantsuit.
Corrected entry: Throughout the movie, Velma's hair is very plain and unstyled and she's not wearing any make-up. After the scene where she gets back control of her body, her hair is styled and she's wearing a lot of make-up. After about five minutes, her hair goes back to looking plain and she's not wearing any make-up.
Corrected entry: At the end of the movie when Scooby jumps into Shaggy's arms and knocks him down. Shaggy is already falling backwards before Scooby actually lands on him. The CGI animators did not quite synchronize the jump.
Corrected entry: In the first scene when Daphne has been kidnapped by the ghost, her scarf is around her neck, but when the ghost finds Shaggy and Scooby in the barrel, the scarf is around her mouth so she can't speak. How did the scarf get around her mouth?
Corrected entry: Just before the monsters atack in the restaurant area and the monster grabs the owner (really Scrappy Doo) and the floor goes up, it clearly shows that Daphne's feet are through the floor - really bad visual effects.
Corrected entry: When they arrive at the theme park the sign can be read normally by those leaving the park. This would mean that the sign was backwards to those arriving by boat.
Corrected entry: Right after their first case of the movie, the gang gets into a tiff, and leave in seperate cars. Why did they all arrive in separate cars when they have the mystery machine?
Corrected entry: When Scooby and Shaggy go to the warehouse or whatever, after being chased by the monster-captured Fred, Scooby says to Shaggy there's bikes under the cover. How did he know that if he hadn't even uncovered it?
Corrected entry: In the scene after the monsters have chased Daphne, Shaggy, Mary Ann, and Scooby-Doo, they are in the vases talking about rescue Fred and Velma. Daphne is talking about them being the damsel in distress, not her, and then she and the vase fall over. When that happens, it's obvious that Daphne is shaking the vase herself so it will fall over.
Corrected entry: This concerns Daphne near the end of the film. When Fred is captured and they call the coastguard she is wearing boots. They wait by the pier and in the morning when they wake she is wearing sandals. When you next see her, when she has been captured and is walking through the caves, when Shaggy releases her soul she is back in her boots.
Corrected entry: When they are in the forest after Fred, Velma, and Daphne get their protoplasm back and they start changing voices. Why does Shaggy's voice switch too? It doesn't make sense because his protoplasm was never stolen.
