Ambam the gorilla turns 25

Most gorillas walk on all fours leaning on their knuckles but one gorilla called Ambam is doing things his own way.

He wanders around on his hind legs, just like a human. He became a YouTube star a few years back for his walk.

This week, he celebrated his 25th birthday and keepers at the animal sanctuary in Kent, where he lives, gave him a tasty cake to tuck into.

Happy birthday Ambam!
