Little boy and baby gorilla play together at zoo

Footage has emerged of a five-year-old boy and a baby gorilla getting on like a house on fire at Fort Worth Zoo in Texas, USA.

The little boy can be seen running up and down outside the gorilla enclosure as the little chimp inside follows him from one side to the other.

Even when the enormous gorilla behind him sits down and blocks his path the little critter skirts around him to make sure he can still play with his new friend.

At one point when the little boy lies down it even appears that the baby gorilla tries to mimic him by crouching down at the same time.
