Scooby-Doo (2002)

Continuity mistake: In the beginning of the movie during the skateboard scene with Shaggy and Scooby riding along the conveyor belt, Scooby grabs a hook and both Shaggy and Scooby jump off of the skateboard. You see the skateboard falling off the conveyor belt, but in the next scene it is on the conveyor belt and being crushed. (00:03:20)

Shaggy: Who's your best buddy?
Scooby Doo: Raggy.
Shaggy: That's right. And who's my best buddy in the whole wide world?
Scooby Doo: Rooby Doo.

Trivia: When Shaggy looks out into the cavern, he looks like he is about to cry, for no reason at all. This is because there was a scene directly before it in which Daphne's spirit thing was sucked out and she turned into a monster, which was eventually cut because it was too scary.

Question: In the shot of Scooby and Shaggy in the Mystery Machine leaving the Wow-O-Toy Factory, where were they headed?
