Saturday Mash-Up! Live

1. Episode 1

This week Extreme Mountain Challenge, Deadly 60 and former Strictly Come Dancing star Steve Backshall will be in the studio, discussing his animal adventures, answering questions from viewers and taking part in some hare-brained games. Steve will take on the fearsome Push Off challenge- but will he avoid a mash-up gunging? Throughout the morning viewers can get involved in the Make Me Viral challenge - who will get the nation talking with their videos? Can you get in touch to guess 'how many things are in the thing?' To top it all there will be cartoon fun with Danger Mouse and a brand new episode of CBBC favourite The Next Step. So stick with Saturday Mash-Up! – the show where anything can happen….except cooking!
