Factual error: Dora picks up the solid gold statue - by the size it would weigh in excess of 500 lbs. She then lifts it up and places it back on the mantle above her head. A grown man could not do that, let alone a child. (01:31:06)
Visible crew/equipment: As the log rolls down the hill with Dora and her friends, for a brief second in one of the shots, you can see either a stunt crew or other production person on the far right of the screen. (00:43:00)
Continuity mistake: Before Dora and friends enter the city the moon is half-full. When they enter the place it's a full a moon.
Factual error: A group of elephants runs behind Dora, there are no elephants in South America.
Continuity mistake: When Dora is talking to Randy by his locker she puts the cupcake down in his locker to draw on his shirt. In a later shot when the bell rings it appears back in her hand.
Suggested correction: She picks it back up as she puts the marker back in his locker.
Continuity mistake: When Dora offers Diego the chocolate biscuit it looks gray except for a brief shot where it looks dark blue (as the package does). Then it swaps back to grey.
Continuity mistake: When Dora finds the bad guys' camp in the jungle, Sammy and Randy are meters behind catching up. Sammy stops and Randy walks up to Dora, leaving Sammy 5 meters behind. A shot later Sammy and Randy are standing side by side.
Continuity mistake: When Dora and her friends find her parents' abandoned camp the stuff next to a red box changes positions between shots. Check the light blue box, for example.
Continuity mistake: When Dora arrives at the airport the passers-by have no continuity between the front and back shots.
Continuity mistake: After Dora feels embarrassed at the school dance she is comforted by her Grandma. Her fringe swaps between parted or not between shots.
