There was monkey business aplenty when keepers introduced a hay-stuffed enrichment ball to a group of mixed small primates.
Staff installed the ball in Monkey Tails, much to the delight of cheeky squirrel monkeys who immediately pulled the stuffing through the meshed wire to get to the treats inside – totally oblivious to the poor little saki sitting beneath who found himself covered in strands of hay!
And by chance keepers had a camera to hand to record the mischief!
