Character mistake: When Sam pushes Freddie off the plane, his mother puts on the parachute and jumps out as well. She is in such a hurry, that she doesn't buckle the straps across the front.

Character mistake: When Dracula puts Johnny on a time-out, it is shown that Dracula has the ability of psychokinesis. Yet during the scene when Mavis visits the human village, when one of the dressed up zombies loses its head, Dracula jumps into the scene to physically put the head back to its body, further risking being spotted by Mavis, which he wanted to avoid. (00:16:15)
Suggested correction: Using this power would also be a risk of Mavis finding out because his magic has blue effects around which she would spot.
I doubt that, she was facing the opposite direction of the headless zombie the entire time, and the zombie didn't stand too close to her. However, I have realised that the magic does seem to make sound, and the headless zombie did stand close enough to Mavis for her to would have heard Dracula's magic if he were to have used it.
Even with the sound, I doubt she would have noticed when there are what looks like villagers approaching her with pitchforks and torches.

Character mistake: When Harry takes the kids to his business, he's showing them how he "restores" cars. After putting the bumper on, Harry says, "Transmission. The sawdust quietens the gears and let's the engine run as sweet as a nut." Putting sawdust into the transmission would not change how the engine runs as they are two separate components. It may make the transmission quieter but would have zero effect on the engine.
Character mistake: In the Swedish version, Riley's first name is changed to Jenny. However, in the scene where Joy, Sadness, and Bing Bong are inside the soundstage of Dream Productions, the director can be heard calling Riley by her original name twice. (00:52:40 - 00:53:40)
