Trivia: On the back of the carnival worker's leg is a tattoo of the Pizza Planet delivery truck.
Trivia: Don Rickles was signed on to reprise his role as Mr. Potato Head, but sadly died before recording any dialogue for the film. However with his family's approval, the production team went through everything he'd recorded in the past for the Toy Story franchise, including games, shorts, theme park material, etc. They managed to get together enough previously-unheard material that could be used for this movie, ensuring his characterisation could live on.
Trivia: One of the children at Kindergarten is Boo from "Monsters Inc".
Trivia: There is a post credit scene with Duke Caboom jumping on the "I" of the Pixar logo.
Trivia: When they enter the pinball machine, the clockwork one man band toy is seen, from one of Pixar's very early films. Bo Peep speaks to him.
Suggested correction: Not exactly a mistake considering he bought a rental.
That's a self-contradicting statement. Buying something means you have ownership of it. Renting something means you pay for its use with the understanding that it will be returned at a specified time. You can't buy a rental any more than you can rent something you buy.
Suggested correction: At best it's a character mistake. As he was exasperated as Bonnie's mother says to her "Daddy's going to use some words" apparently meaning he was going to swear.
If it's a character mistake, it's still a mistake, so no correction is needed. I think it's a valid other mistake because it's the screen writers flipping back between owning and renting, but not an actual plot hole. I've been exasperated with a rental before and never in my anger or frustration said I bought the rented item.
