Corrected entry: In the first movie, Andy's mom is a brunette with long hair. In the second movie, she has short blond hair. Even if she cut and dyed her hair, her face appears entirely different between both movies.
Corrected entry: In the first film Mr. Potato Head has no compartment to put his accessories in, but in the second film, he has one.
Corrected entry: It would be impossible for just one of Mr. Potato Head's feet to be stuck in the gum(in the street crossing scene). Feet for Mr. Potato head are made in one piece, as shown when he tries to put on his "angry eyes."
Corrected entry: When Woody and Jessie jump off the airplane and are saved by Buzz, you see that shortly after they get off, the plane takes off. In the next few seconds another plane comes in for a landing. The tire flies over the heads of the characters and then lands. It is impossible for a plane to be landing and stopping before the end of the runway where the other plane took off just moments before.
Corrected entry: When Woody tries to get his arm back from a sleeping Al, the main light source is the TV. We know this because the scene fades into the TV ending a program and staying on with Al sleeping. Woody just about has his arm, and the same TV suddenly gets turned on again without ever being turned off.
