When this chimpanzee was found and taken in by the Jane Goodall Institute's Tchimpounga Chimpanzee Rehabilitation Centre, she was close to death.
Suffering from a number of illnesses and losing weight fast, it was a race against time to help save her life.
Dedicated staff worked around the clock, making sure the chimp, named Wounda, received a litre of milk each morning.
It took years and dedication to nurse Wounda back to health, until finally she was strong enough to be released into the outdoors once again.
But, as they released her into the wild, she decided to say thank-you to Jane Goodall in the sweetest and most touching way possible:
Is it bad that we're crying?
The tender embrace lasted for several minutes, before a delighted Wounda wandered off into her new life on Tchindzoulou island.
