Joe, Harpz and Stanley host a morning of Mash-Up fun – with a difference! Saturday Mash-Up! House Party takes the show out of the studio and into our presenters' homes! The gang will chat to top celebrity guests, play brand new games and bring you the very best shows, including Dragons: Race to the Edge, She-Ra and Crackerjack! And you can get involved – tune in to find out how.
