Kate is no stranger to the group as she worked as a volunteer with a Cub Scout pack while living in Anglesey with Prince William.
The royal mom joined the kids as they played parachute games, decorated cupcakes and feasted on a 100th birthday cake.
The Duchess of Cambridge, née Kate Middleton, even had her arm put in a sling by one of the Cubs during the first aid event.
Catherine wore a turtleneck jumper, khaki skinny jeans, a pair of Really Wild brown boots and the Cub Scout scarf.
