Coming of age and celebrating their 18th birthday, the chimps were thrown a birthday bash to enjoy.
Laden with treat filled presents to unwrap and a huge cardboard cake, Phil and Grant were spoilt rotten with nuts and sultanas and their favourites, bananas and grapes.
Not wanting to miss out, the other chimps joined the mischievous duo, getting in on some birthday fun.
Zookeepers at Whipsnade have a soft spot for Phil and Grant, who were named by none other than Pat Butcher (Pam St Clements) when she visited the zoo. Speaking at the primate party, zookeeper Graeme Williamson described the chimps, he said:
"Grant is known as a bit of a greedy chimp. He loves being the centre of attention and trying to get his hands on more of his favourite treats, especially banana, grapes and monkey nuts.
"Phil is the smaller and shyer of the two. He can often be seen swinging from ropes in the Zoo's 'Chimpnasium…they love investigating new things."
And when they came across their cake and presents, investigate they did, tearing open the wrapping paper and digging straight in.
We've never seen a happier bunch of chimps.
Happy Birthday Phil and Grant!
