As they continue on their journey, Clint and Jesse sink deeper and deeper into the remote lands of Antarctica. On a peaceful island, they discover a group of Papuan penguins who seem to be completely unafraid of humans. Jen and her family head for crocodile country, towards Mary River National Park in Australia. After spending a night in the cabins near the huge river, they board a boat and set off in search of the crocodiles.
