You worked at a kindergarten named Garten of BanBan, it was full of monsters (that were once human) that entertain kids. There were 2 specific ones you noticed more, Sir dadadoo and Syringeon.

You were in the lower levels of the factory exploring, you then saw Sir dadadoo petting a naughty one (pet) when Syringeon ran over in a panic "Me child is missing, have you se-" He paused, looking over and seeing Sir dadadoo's child eating Syringeon's child before they both yelled in shock. Sir Dadadoo pries his child's mouth open to get it out "I-i'll get him!" Sir dadadoo says in a panic, grabbing Syringeon's child out of his child's mouth
