Damian Aspinall searches for Kwibi, a lowland gorilla he hasn't seen for 5 years. Kwibi grew up with Damian at his Howletts Wild Animal Park in England. When he was five, he was released into the forests of Gabon, West Africa as part of conservation programme to re-introduce gorillas back into the wild. Now Kwibi's 10 years old, much bigger and stronger. Will Damian find him?
