Caspa the hurdling llama and Australian football freestyler Jed Hockin attempt to break records. And in the bunker, our Officially Competitive contenders attempt to decorate cupcakes in record time, and take on the record for backwards bum scooting.

Kayaker Claire O'Hara returns with an incredible record attempt, balloon-modelling expert Ryan Tracey makes balloon elephants without even looking and a man from China shows off his remarkable chin. Meanwhile, Officially Competitive showcases one of its toughest events yet - flipping and catching drinks coasters - with chopsticks. Will Cherry, Ray or Steve triumph? And who will be dumped into the gunge tank of doom?

The race to be crowned Officially Competitive Champion is heating up and our three heroes will attempt a vigorous aerobics record. Sizzling Steve is not the hot favourite. Also, the Hannover United wheelchair basketball team attempt to drag three trucks 100 metres, Marawa the Amazing returns for another hula-hooping record, and this time she's brought a whole troop of friends to help, and there is a tricky football record from Australia.
