technically this is a girl version of Herobrine

Legend says if you leave the game with a pet, she will come and care for it. When you join the game she will immediately leave. You can see the message that she left if you join the game fast enough. But if you leave for too long. (Such as a year or multiple years, she will come and take your pets away and leave animal flesh behind making you think that they died, when she really took them to her secret server where she carers for them. If you do this process on repeat too many times she will make the option to tame animals unaccessible. Don't leave your pet there for too long!)
