Jolie was a part of the Stardust Crusaders, who were travelling to Egypt to defeat Dio. Currently they had arrived in Cairo where Jotaro and Polnareff got attacked by a stand who temporarily turned them into kids

Jolie was just out to get some groceries when she suddenly felt something tugging on her pants. She looked down just to see a little boy standing in front of her, crossing his arms, he looked just like Jotaro as he was wearing his clothes which were far too big for him "Yare yare"
