Saturday Mash-Up Live! S02E08 - With the Next Step, the Vamps, Sapphire Sings and Strictly

The cast of The Next Step are live in the studio all morning - but who will get slimed? Online singing sensation Sapphire performs live, while The Vamps are in detention. Plus Hacker takes a trip to Blackpool to go behind the scenes at Strictly Come Dancing. There's cartoon action in two brand new episodes of Dragons: Race to the Edge as well as Push Off, Musical Toilets and How Many Things In the Thing. It's totally live - so anything can happen! Yasmin Evans, Jonny Nelson and Hacker T. Dog host.
