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: 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 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: 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: 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: 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.
