Reggie Yates watches on as another team of celebrities try and out run the hounds. The Box's AJ Odudu, Maya Jama and Will Best must face the sausage maker from hell, a zombie scientist and the world's creepiest bird watcher.

In this edition, the stars of Love Island swap cocktails and sunshine for rat monsters and a pitch black forest. Chloe Crowhurst accompanies couple Marcel Somerville and Gabby Allen on the muggiest night of their lives. Will Gabby and Marcel's fledgling romance survive the trauma? Will Chloe stay single or fall for the Hounds?

In episode two, Emmerdale cast members Danny Miller and Adam Thomas are joined by Love Island's Scott Thomas (who is also Adam's twin!). They'll encounter freaky children, a haunted ambulance and an art gallery from hell.
