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.
Plot hole: Kerchak is mad with Tarzan because he showed Jane, Porter and Clayton to the gorilla's current location. Yet he does not move the group even though he obviously knows they're no longer safe there.
Suggested correction: He does actually move the group later on in the movie. Then they get ambushed by the hunters and he is killed.
