Continuity mistake: After Chuckles tells the story of Lotso we see the gang locked up at the daycare center. Jessie comforts Bullseye and looks at the word "Andy" on her boot (with the "A" on the inner side) . Woody returns and when the bell rings for the kids to go outside, we see Jessie on the floor. Notice that the "Andy" on her boot is now different (the "A" is on the outer part of her boot). (00:52:50 - 00:57:10)
Continuity mistake: Just before Flynn cuts off Rapunzel's hair, there is a shot from behind him and he reaches up with his right hand to push her hair behind her ear.
