Deliberate mistake: Puppy Clifford engaged in a "tug-of-war" with a Rock Dove over a French fry and the Rock Dove WON, yanking away the French fry. Overlooking for the present purposes that the French fry did not even appear to be into animated Clifford's mouth, a Dove weighing maybe 13 ounces is no match for even a 5-pound puppy. Clifford probably weighed closer to 10-15. (00:10:40)
Deliberate mistake: When Max knocks out Jeff with a pool ball, he later wakes up with a VR headset on his face, and he is able to see his body and the outfit he is wearing within the VR environment. This is very obviously not how VR works - you are not able to see your own body while in VR, just the environment you're in. This might have been done deliberately so that Jeff was able to see his movements, but it's still a mistake. (01:05:10)
