After Tulip receives Nate's letter and leaves the room Junior assigns her to, she is caught on the security cameras. When Junior sees Tulips on the security screen while in Hunter's office, Tulip is shown to be crossing the bridge between the Cornerstore building and the baby factory and it is depicted as daylight. However, shortly after Junior leaves Hunter's office, when he is crossing the bridge, it is night.
When Nate's dad comes outside to check on Nate, there is a ladder and the third plank is hanging, weakly secured. A moment later, the plank is secured safer without explanation; as Nate and his dad were too busy talking.
Junior's teeth appear and disappear throughout the movie.
When Nate puts his envelope in the mail to send to the storks, the envelope/stamps are already canceled.
Nate has brown eyes. Both his parents have blue eyes.
While Pigeon Toady is in the tundra, he encounters what appears to be a baboon. While baboons only live in Africa and Saudi Arabia and not the tundra, the animal in the film is actually a Japanese macaque. While technically not a tundra animal, but native of the forest regions of Japan, macaques use natural hot water springs to bath -as shown in the movie- during Japanese freezing winter temperatures and have been nicknamed "snow monkeys".
The tundra wolves have dark fur. Due to the cold climate conditions, their fur should be white.
Despite living with the storks her entire life, Tulip is unaware of the annual Storkcon event and has to have Junior explain it to her.
