I'm genuinely shocked by the story of Pony. My imagination was completely pre-empted here.
However, there is no orang-utan called Pony in Monkey World to my knowledge. I'm assuming that she was taken to a sanctuary in Borneo instead. I'm assuming that it was the Orangutan Protection Foundation (
http://www.orangutanprotectionfoundation.org/) as they were the ones to rescue her.
