Other mistake: To save Sunshine from the general, Dex pulls on a rug to make sure the general falls backwards. However, Sunshine was also sitting on a chair on the same rug, but both her and the chair are unaffected by the rug being pulled. (01:14:05)
Other mistake: When Cheasel attempts to cut the wires to the telephone pole, he takes out a chainsaw, bumps into a wire with the chainsaw slanted, then bumps into part of the pole with the chainsaw straight. He chops through the pole at a straight angle, but the area where the pole begins to detach from was never touched by the chainsaw. (01:11:00)
Other mistake: When Cheasel is about to be trapped by the wrecking ball, he is shown with his head and neck visibly extended whilst the ball is shown placed over his back. The wrecking ball then crushes Cheasel but his head and neck are crushed along with him, even though the ball was only shown landing on his back. (00:30:25)
Other mistake: After the first Copa-Banana scene, Dex is back at his apartment and pours some milk into a cup. When he finishes pouring, some of the milk he was pouring spills onto the table and the milk that is spilled on the table begin to land to the left of the cup. The shot then pans around to close in on the cup of milk, and an error occurs in the animation, as in the same shot, the spilled milk moves around the cup to a different position at another side of the cup. (00:22:15)
Other mistake: Whilst Dan's plane is crashing the second time, there is a shot from behind the plane where it shows the plane headed for a tree and also shows the plane mere meters from it. Dan spends the next twenty to thirty seconds trying to maneuver the plane and also attempting to pull the ejector seat, before finally crashing into the tree. Given the short distance between the plane and the tree in the reverse angle and also the twenty to thirty second gap of Dan attempting to maneuver the plane, as well as eject, the plane would have definitely crashed into the tree in a much quicker time than Dan had spent attempting to fix the plane. (00:14:35)
Other mistake: When Dex is walking down an empty street, Cheasel appears between his legs before moving his body around so that he is in front of Dex, whilst his head and neck remain in the same position. If Cheasel had his head and neck between Dex's legs, he would not have been able to move his body around Dex, as Dex's legs would have been in the way. (00:29:15)
Other mistake: When Dex pulls on the rug to make the general fall backwards, the general's reaction is delayed. Dex pulls on the rug, and then it takes a full second for the general to fall. (01:14:05)
Other mistake: The Brand X general instructs two of his soldiers to seal Dex and Dan into Mr. Leonard's office. The two soldiers do this by jumping onto a tube of glue which squirts onto the top of the door, moves around to the edge of the top and moves downwards, however the soldiers only jumped on the glue. They did not do anything to move the trajectory or direction of the glue. (00:43:50)
Other mistake: After Dex lures the hairless hamster henchmen away from the hot air balloon with a piece of cheese, they leap off the balloon to try and reach the cheese and they plummet to the ground. When the final henchman is falling from the sky, Dex and the Fat Cat Burglar are visible in the far background, but they are paying no attention to any of the henchmen plummeting and are instead just looking at each other. Given the fact that the Fat Cat Burglar has just lost his henchmen and Dex needed to make sure they were out of the picture so he could rescue the baby kittens, there is no real reason that they would ignore the henchmen falling.
