Monkey Life (2007) : 1x13

The vets examine 17-year-old chimpanzee Freddie, who does not seem to be his usual boisterous self, and the staff wait to see if chimp Joline will recover from her mystery illness. In the nursery, youngsters Pip and Ben take a big step when they venture outside to play for the first time, and their new housemate, Bryan, is given a health check.
