Continuity mistake: When Jesse and Bullseye are at Andy's house, the letters on Bullseye's hoofs are written so that when it says Dany, the A is on the front left hoof, D is on the back left hoof, the N is on the front right hoof, and the Y is on the back right hoof. When he switches the letters to Andy, the A and Y stay on the same hoof, but the D and N switch hooves. (Note, our left and right, not Bullseye's.). (01:22:40)
Continuity mistake: In the German Version: The group arrives at the Toy Market and a sign says "GESCHLOSSEN". The next time it is shown it says "CLOSED". (Geschlossen is the German word for closed).-It happens in the French version as well and in other Pixar films too. They arguably translated the most obvious words so that foreign people can understand, but they forgot some of them.
Other mistake: During one of the outtakes between Mr. and Mrs. Potato Head, Mrs. Potato Head packs a set of toy "teeth". In the DVD subtitles for this scene, it's printed as if she said "cheese".
Deliberate mistake: Even though Hamm is flicking through the channels at the same speed, the side with Al's advert on it is visible for longer.
Plot hole: At the end when the gang get home to Andy's room, it's night time and the luggage trolley they drove home in is outside the neighbour's house. The next morning it's still there. But we see an ad with the 'chicken man' looking very sad because he lost Woody and the others. How could he have gone to Tokyo, realised the dolls were missing, then zoomed back to Tri County to do the ad the next day? While saving Woody, the toys explicitly say that Andy is returning home the following morning. They must have made it in one night, or they would have missed Andy's return.
Continuity mistake: In the baggage area when Woody fights with Pete, his arm is torn (an injury which had previously rendered it useless). However, in the next scene going to rescue Jessie, he is using the arm freely and there is no sign of a tear or fix. There is then reference (and visible signs) later in the film that the arm has been fixed.
Factual error: Near the end of the film when Jessie and Woody escape the plane, Buzz and Bullseye stand on the runway. In the sky you can see a plane approaching and it passes just above them. A real plane can blow away an entire car when it's behind the engine, yet nothing happens to a bunch of toys.dux
Other mistake: In the last scene with the baggage plane, Woody, Buzz, etc. are all near the plane when it takes off. Since they were following a big jet, they are well down the runway once it takes off. Later, without them backtracking the runway, another plane passes overhead very close, as if to land. There is no chance to land a plane if it touches down that far down the runway. You will not be able to stop in time.
