Audio problem: At the scene where Mikey asks the elder penguin if anyone surfs in Shiverpool, when he says,"You know you're standing on thin ice," his beak never moves.
Revealing mistake: When the elephants are making fun of Dumbo in the train caboose, Dumbo's mother pulls a pin which causes the stall door above the other elephants to fall. When the door bounces back up, you can see that the animators forgot to draw the elephants' heads and trunks and only their bodies are visible.
Factual error: In the very first scene a giant squid swims past Fujimoto. It swims in the wrong direction however, with its tentacles in front. In reality squid swim backwards.
Other mistake: Grand-Santa has made 70 missions, and Santa (Malcolm) has just completed his 70th mission, totaling 140 years. Yet Grand-Santa is only 136 years old.
Suggested correction: Grandsanta's portrait is shown in the halls of the North Pole with the dates 1902-1941 (with Malcom having done 71 missions from 1941). Therefore he did 39 missions. That makes for a total of 109 years, meaning he was 27 when he took over from his own father.
Continuity mistake: In the beginning when the photo of the Master is broken, the pieces of glass change position and then disappear altogether.
Continuity mistake: When Ralph sticks Sour Bill to a candy tree, the branch is directly under Sour Bill, but when Vanellope has become a princess later on, the branch is now facing Sour Bill's right. (01:13:00 - 01:28:15)
Other mistake: When the mayor is talking behind the chainlink fence, with Brent in the background eating sardines, you can see as the mayor grabs the fence, his thumbs clip through the fence wire. This occurs on both hands and easily visible, particularly when Mayor Shelbourne says, "Otherwise, I'm just a tiny mayor of a tiny town full of tiny sardine-sucking knuckle-scrapers." (00:10:52)
Suggested correction: This isn't really what happens, although it looks like it does. The mayor's thumbs are not pointing outwards, they are curled around the fence wire. As he continues to grab the fence, his thumbs don't clip through it, they curl more and more around it, getting a tighter grip on it. Then when Brent says, "But not me, right?", he lets go, and you can see his thumbs curl back out. This is all visible if you look close enough.
Continuity mistake: Kamaji bangs the work surface, causing a chopstick to fall to the floor, but in a following shot both chopsticks are back in the bowl. (00:23:00)
Continuity mistake: Following Rodney's step from the escalator on the red pedestal he is being scooped into one half of a wire-frame globe/ball. Two halves now (the other one has Fender in it) form an intact globe. A safety bar with a 'wooden' middle bit (like those on rollercoasters) suddenly appears. After their journey, when the ball splits back into two halves, the safety bar, which previously had mysteriously appeared, now has disappeared.
Continuity mistake: When Shifu performs the Wuxi finger hold on Po, in one shot, we see all of Po's fingers, except the one Shifu is holding, are closed to his palm. In the next shot, all his fingers are open. (00:22:05)
Suggested correction: If you slow down before the part where the camera pans onto Po when he's surprised, his fingers open.
Other mistake: When the ride finishes, there is no sign of a safety bar in Gru's cart.
Continuity mistake: When Melody is in her room getting ready for her party, at one shot her hair is down. In the next shot of her, it's in a ponytail, and in the next it's down again.
Continuity mistake: Chief is tied to his kennel around the collar. But when Copper cuddles up to him for the first time, the rope tied to his collar disappears for a shot. (00:10:35)
Factual error: The size of the shadow of an object depends upon its distance from the light source, not the surface it falls upon. Lifting the cutout of the bird a few inches closer to the sun as they do would make absolutely no difference to the size of its shadow, yet it quadruples in size.
Plot hole: In the beginning, vampires are shown to be invisible in photos but then they seem to appear in videos like security footage and social media posts.
Continuity mistake: During the other father's song, notice the red record player by the door and the position it's in, with the lid facing Coraline when he says, "making up a song". When the camera angle changes and he says, "she's a doll", the record player's position changes completely, with the lid now facing the wall.
Continuity mistake: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer, and the lid is back on. (01:29:00)
Plot hole: The whole plot of the first "Brother Bear" was that Kenai had to go to that mountain to become human. But at the end of this movie, the spirits were about to change Kenai back into a human in the middle of a cliff, which makes the entire first movie completely pointless.
Continuity mistake: When Pleakley is tipped out of the chest, he is accompanied by lots of Lilo's toys. When Stitch activates the pod, the toys have vanished from the floor around Lilo and Pleakley's feet. (00:15:15)
