One day I was peacefully playing Pokemon ORAS...then I saw in a small milliframe...THERE WAS A LITTLE GIRL IN PHOEBE'S CHAIR!!! Then I thought it was a little glitch in the programming...But no...when Phoebe continued talk...the camera shifted as if something hoped off of the chair's point of view. Like lets say...a little girl! Walking towards me!!! Then the camera shifted again. THEN OVER MY LEFT SHOULDER WAS THAT SAME LITTLE GIRL!!!
Please, if you have any answers to why the girl haunts Phoebe's room, please answer me.
PLEASE THIS THING IS EATING ME FROM THE INSIDES .-_-.
It was probably put in there by GameFreak on purpose. Phoebe specializes in Ghost types, so as a surprise, the creators of the game put the little girl there. Source
Long story short: for promotion and to create some kind of a buzz.
