INCREDIBLE footage has emerged showing a group of explorers discovering an incredible underground cave – in the tiniest of holes.
The clip begins with a cargo-trousered bloke desperately squeezing himself into an opening.
He first shoves his top half in the gap before getting stuck momentarily as he tries to squeeze his bum in.
With some more wriggling, he manages to finally get into the hole.
The camera then cuts to the lad in what looks like the entrance to an underground cave.
