The monkeys at Wellington Zoo have a treat on the way, thanks to the Henley Men's Shed and a group of girls from St Matthew's Collegiate School.
The girls have just completed a climbing frame adorned with plastic jars which will be placed in the monkey enclosure.
Different food items will be placed in the jars, and it will be up to the animals to figure out how to access the food.
Stimulation is important in keeping the monkeys healthy and happy.
The girls benefit too, designing the play equipment and then building it, with supervision from Men's Shed members.
