Jonathan and Todd were hoping to do a dive with world-renown cave explorer Robbie Schmittner...but Robbie forgot his drysuit. So handed them a strange device called a Mnemo and sent them into the cave alone. Here's what happened! WARNING Cave diving is incredibly dangerous. Do not attempt to dive in caves without proper training and equipment! JONATHAN BIRD'S BLUE WORLD is supported by the Bharat Family Foundation.
