Moanda, who's the only male baby gorilla to be born at Blackpool Zoo, turned ONE today.
And his keepers pulled out all the stops to make it a special occasion.
Njema, who is 19, gave birth to a healthy baby in the early hours of November 8th following a natural and uncomplicated labour.
The baby, whose sex is yet to be determined, has been an instant hit with two year old Meisie the gorilla, who is intrigued at the prospect of having a new playmate!
First time mother Njema underwent revolutionary fertility testing earlier this year after keepers became concerned that she had not conceived.
