Other mistake: After the great fire scene there is a raccoon that drags her baby to shore and begins cleaning it. A few seconds later the baby has jumped across to the other side of his father and siblings, but the mother does not stop licking.
Other mistake: Even though it is snowing throughout much of the movie, none of the snow seems to stick to any of the characters' fur. Even during the fight scene when they are rolling around in it, they are never covered with white.
Other mistake: Ginger is adamant that she will not approve any plan of escape that does not get all the chickens on the farm out and to freedom. The problem is, not one of her plans gets anywhere close, and it is not that they fail to liberate the whole farm - they are never planned that way. We see her trying to escape by herself three times. The mannequin of Mrs Tweedy would (had it worked) have allowed nine chickens to escape, the upturned feed tray just seven. Even the 'crate' appears to hold not more than thirty chickens - and there must be several hundred on the farm, at least.
Other mistake: When Rex shakes the table causing the baby monitor to fall, the batteries fall out and we see the open battery compartment with markings for positive (+) and negative (-), and space for two AA batteries. Woody jumps off the bed and places the two batteries inside the compartment, but before he closes the compartment note the position of the battery closest to the top of the monitor. The positive side is actually where the negative side should be so the monitor should not work, but the monitor turns on just in time to hear the soldier's warning. (00:13:15)
Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Other mistake: After the magnet grabs Slink during the incinerator scene, all the toys grab metal objects to avoid getting torn up. Afterward, they all let go of their metal objects to drop down. However, Slink also drops down despite not holding on to anything because he is made of metal.
Other mistake: At the end of the show when the misfit toys are being delivered, the elf in Santa's sleigh gives an umbrella to each of the misfits so they can glide down with the exception of the bird, who jumps off, apparently forgetting that he is a misfit toy and can't fly; as he stated earlier in the show, he can only swim.
Other mistake: When the switch is thrown to electrocute Terrence and Phillip, it's pulled downwards. A few shots later, we see Cartman jump in to save T and P by turning the switch off. He also pulls the switch downwards instead of pushing it upwards. (01:06:05)
Other mistake: During the Battle of Teth (the pillared jungle planet), the AT-TE's shoot the ledge at the top and there's not a single mark on the ledge afterwards, despite being hit with several joules worth of fire.
Other mistake: While the wizard is speaking near the portal, a ghost image of him appears to the left.
Other mistake: When the Dwarfs first leave the mine entrance, the first few animation cells seem to have been omitted, so that at first the entrance is empty and then the Dwarfs appear out of thin air.
Other mistake: Anna is shown from the front as she ascends an ice staircase inside Elsa's ice castle. There are giant ice pillars to Anna's right and left. They should reflect the side of her face, but instead the reflections show her face from the front.
Other mistake: Sam draws an orange vest for Lockwood using a dark crayon. (01:10:45)
Other mistake: When Hamm turns off the TV at the beginning, there's no reflection of him, Rex who is beside him, or the remote. (00:06:58)
Other mistake: When a glass of milk is poured, if you look closely, the glass is filled but the level of milk in the bottle doesn't seem to lower. (00:16:00)
