After Pippi tries to sell the sewing machine and rushes around to the other door, it is green. When she opens it and pulls it open, the camera view is from the inside, but she is pushing it and it is not green but wooden.
Pippi walks down the wall out of the orphanage, and must jump out of her shoes. It doesn't show her putting them back on, but she is seen with them on in the next scene, throwing the message in a bottle into the sea. In the following scene, when the orphanage is on fire, she suddenly has no shoes on and must put them on to climb again.
When Pippi, Tommy and Anika are riding the horse/motorcycle through town, palm trees are quite visible throughout the town square. Yet, in the Christmas scene, it is clearly snowing and people are bundled up in the cold.
