I thought it was FFXIII-2 spoilersEtro that changed her? I gotta read up on my lore more often.
EDIT: Yeah I was right, Chocolina wasn't simply "willed" into being human. FFXIII-2 DLC spoilersIn Sazh's DLC sidestory, the human Chocolina reveals herself as the chocobo chick given human form by Etro while lost in time. Etro also gave her the ability to exist in multiple times in places to help Serah Farron and Noel Kreiss in their adventure.
EDITRA: Oh, and if anyone else was curious, apparently it's confirmed that those are gloves and slippers etc, not actual bird-body-parts.
