1. The Little Boy
"I am going to tell you a story about a little boy. He had a rattlesnake that he kept in a metal cage, whos hunger could not be satisfied. One day, the boy found 5 baby kittens outside his house. He brought them inside and kept them in a shoebox. He knew that the snake would kill them but could not bring himself to get rid of the snake. He knew that if he chose one kitten to feed to the snake, it might be satisfied. But he could not choose, so he went to bed leaving the cage open. The snake went to the shoebox, chose a kitten at random and ate it. After 5 days had gone by, the boy was full of regrets and cut the snake open. He pieced the remains together and put the kitten back into the shoebox."
2. The Kind Man
"Now I will tell you a story, a story about a kind man who would visit 5 orphans and give them toys and/(in?) gladness. The man lived alone and lived in fear that someone might break into the house of one of the five children so he adopted all 5 and brought them together in one place in his own home. He promised them to never leave them, and they promised to always come home and never stay out too late. He left one day to buy food, his heart being filled with gladness but returned to find that the burglar had chosen his home and killed all 5 of the children. The man could only afford one coffin so he stitched the 5 bodies together to make one and buried the child. That night, there was a knock at the door."
3. The Young Woman
"Now I will tell you a story about a young woman who was sealed in a small room. In the room was a furnace and 5 keys. She was told one of the 5 keys would open one of the five doors outside her room. Inside each room was a child that she could take with her as she fled the building. But she was only allowed to leave her own room with one key, not all 5. Desperate to find a way to save all 5 children, the woman melted the five keys together in the furnace to create a single key hoping it would unlock all 5 doors. Of course, it did not work that way. Now her key opened none of the doors. Rather than leaving her room with a key to one life, she had taken with her a key to five deaths."
This is my theory on what Candy Cadet's stories are. I have been lead to believe that FNAF 6 is the last game in the series, so I think that adding more lore to the story would just make it all confusing and difficult, especially when we are so close to getting the whole story down. I believe that every lore piece in FNAF 6 is just an additional piece to the story that we already know. With this in mind, I think that Candy Cadet's stories are just pieces of the lore that Scott is just trying to correct, so that we as the player can finally understand whats going on and strenghten whatever story that we have already gathered.
For example, I believe that the first story is about the animatronics in Sister Location. The second story is about Ennard and William Afton. And the third story has some corellation to the mother, maybe?
These are not my final thoughts, just some suggestions that I hope the FNAF community can piece together. :)
EDIT: What if the 5 objects in each story is actually foreshadowing only one object IRL? But is portrayed in different perspectives by different people? Like, maybe the keys, kittens and children are one and the same, which are the 5 children that got kidnapped in the first game (because it seems to always lead back to them). And are seen by different POVs? Like maybe the little boy is the crying child, the kind man is Michael? And the young woman, again, the mother maybe?
