Joe, Stanley, Kia and Shereen host a huge party to celebrate the coronation of HM King Charles III. Comedian and artist Bec Hill creates a giant piece of artwork to mark the special day, while Strictly's Carlos and Jowita, comedian Philip Green and Bake Off's Crystelle Pereira compete in a series of challenges to try and avoid a sliming. Stanley heads to London to find out more about the big occasion, and two families take on a game of Royaloke! Plus cartoon fun and a special music performance.
