Continuity mistake: In the scene where Shrek goes back to the swamp after signing the contract, he realizes that Fiona isn't there and pulls out the contract to read it. He then notices something flying overhead and looks up to see the witches. In the next shot, we see no contract in Shrek's open hands. (00:22:30)

And after leaving the castle, Donkey found a waffle and got pulled toward the ogres' hiding place. Once inside the hiding place, Shrek tried to take Donkey away from becoming a "dinner" by saying "Your dinner is my friend."

Continuity mistake: When Shrek and Fiona are fighting the dragon, the amount of chain between Shrek and the dragon changes after he wraps the chain around the dragon's tail.
Continuity mistake: Fifi the goose changes size throughout the film. From small enough to fit on Rumpelstiltskin's lap, to big enough to pull the cart.
Suggested correction: The goose has magical powers that likely allows it to change size in the film. The scene where the goose jumps on Rumpel's lap is in the past, also. So likely when the goose was a lot younger.
Continuity mistake: In the scene when Pinocchio arrives to request Rumpelstiltskin to convert him into a real kid there's nothing on the table but goblets and kind of cakes, after Rumpelstiltskin asks to the wolf his wig, he suddenly takes the contract from the table and on it appears the feather and ink that Pinocchio uses to sign the contract.
