After found Rochelle at Argos, I headed to mine to see if I could have the same luck. She wasn't there, but I found her at Tesco instead.
There was one right infront of me, so I picked her up and rumaged behind her. At the very back there was another Rochelle so I picked her up aswell and then compared them to one another. I bought the one at the back as she was perfect and the one at the front had less blue in her hair and no side streaks like this one has, some speckles in the corner of her eye and possible slight paint chipping (hard to tell if it was just the speckles). So Rochelle joined my collection.
