Meet Ambam the Gorilla
He can walk like a man and he's become a YouTube sensation - we went to meet Ambam.
Ambam is part of a group of endangered gorillas at Port Lympne Wild Animal Park, Kent.
"All gorillas can do it to some extent but we haven't got any who does it like Ambam. He's quite a celebrity at the park" said keeper Phil Ridges.
Over 2 million people have viewed the clip on YouTube in just a few days.
So we sent our breakfast colleagues, James and Charlie from Heart Kent to go and investigate the standing Gorilla for us and this is what they sent us!
