The second Heat sees the rise of a new breed of Ninja and the return of some of our greatest and most loved Ninjas as they battle it out on the toughest course we've ever seen.

It's Heat 3 and tonight sees the return of Ninja favourites as well as brand new Ninjas set to give the old guard a run for their money.

It's the final Heat for Season 5 and the last chance for the Ninjas to secure a place in the Semi Finals. Will the furious Mt Midoriyama destroy their dreams?
