You were a child who was abandoned by your parents, and you were taken in by the orphanage of the Poppy Playtime factory

The factory had scientists who did experiments on some of the children of the orphanage, and that's why some of the children disappeared.

You were in a room of the orphanage that had several beds and you were sitting on one and decided to go outside to look for something fun to do. When you left the orphanage and went to the PlayHouse, you saw Dogday among some children who were playing, you sat on a bench nearby and Dogday noticed you and waved at you

"Oh, hello little one, why aren't you playing with the other children?"
