Russell’s in the Costa Rican jungle with YouTube singing superstar Conor Maynard for the most foolhardy mission yet, with just their mobile phone to help them survive. The Maleku tribe set the mission, which would be easy if it wasn’t for deadly bullet ants, giant abseils and fast river crossings. Oh, and the fact that, for this task, internet reception rarely gets above one bar. Battling humidity and monsoon, the lads will have to convert their phones into multi-tools – using their backlights to attract grasshoppers for dinner – and rely on the inbuilt compass to navigate them safely back to civilisation.
