Overview: Dominic sails the mighty Amazon River on a mission to find the largest beetle on the planet – the titan beetle. This massive insect can grow up to seven inches in length and wields mandibles so strong and sharp, it can snap a pencil in half. To find this rare and elusive beetle he has to venture into the remote corners of the Brazilian jungle. Along the way, he wrestles with a mighty green anaconda he encounters on the river. Dominic also visits a remote village in the rainforest, where he befriends a group of small children and gets his face painted with the seeds of the achiote fruit, an ancient practice.
