"She looked in the window and then peeped through the keyhole; seeing nobody in the house, she lifted the latch." -Goldilocks and the Three Bears
In the original tale, three bachelor bears live together in a house in the woods. The bears are described as very good-natured, trusting, harmless, tidy and hospitable. Each bear has his own porridge bowl, chair and bed. One day, an old woman discovers the bears' dwelling. The old woman eats the Wee Bear's porridge, then settles into his chair and breaks it. Prowling about, she finds the bear's beds and falls asleep in Wee Bear's bed. The climax of the tale is reached when the bears return. Wee Bear finds the old woman in his bed and cries, "Somebody has been lying in my bed - and here she is!" The old woman starts up, jumps from the window and runs away never to be seen again.
The antagonist was later changed from an ugly old woman to a pretty little girl named Goldilocks. In addition, the bears changed from bachelors to a family of a mother and father bear and a bear cub. Goldilocks' fate varies in the many retellings: in some versions, she runs into the forest; in some' she is almost eaten by the bears but her mother rescues her; in some, she vows to be a good child; and in some, she returns home
"Bears Will Be Bears" pulls clear themes from the original tale of Goldilocks. The young woman does escape from the home by jumping out the window after breaking in and indulging (although she's joined in "testing out the bed" by a young man, who gets kidnapped by the young male bear). However, the Jägerbar creature and the ceremony of Roh-Hatz is a concept original to the show. Though in some editions, the bears do plan to kill her upon finding her, only for her to be rescued by a family member. So it can be taken that Nick takes the role of the family member.
