There's a show in Animal Kingdom called "Pocahontas and Her Forest Friends." It's actually a very intimate show (small audience, seated close to the stage). Pocahontas talks with Grandmother Willow and several small animals that are trained to do tricks. It's located right by the Festival of the Lion King show in Camp Minnie-Mickey.
However, I'm not sure that Pocahontas is available for pictures/meet-and-greet after the show.
Maybe someone else can help you with that.
