The team makes a special journey to Hawaii where they hope to say "Aloha" to the islands' little foot: the Menehune. Taking their investigations across the Hawaiian Islands, they hope find one of these legendary 3-foot tall creatures.

The team returns to the Four Corners of America to find all their previous witnesses have been plagued by recent activity. A search of all 4 states leads to their most intricate strategy yet in hopes of capturing footage of a Bigfoot.

The team is in Arkansas, where a group has put up a bounty in exchange for proof of Bigfoot's existence. To sway these skeptics, the team invites them along on their expedition, but will they be able to surface the proof?

A Bigfoot festival brings the team just outside of Nashville, but it’s a bizarre revelation that motivates the team to invite a country star to come squatching with them. She just might be the bait they need to lure in a Bigfoot!

The search for squatch brings the team to Southern CA, where reports have been rampant. They zero in on the canyons of Deep Creek, enlisting the help of an L.A. local for a night investigation that yields proof Sasquatches are there.

The team travels to Remer, MN to investigate this small town's claim to be the "Home of Bigfoot." As evidence continues to mount, the team pursues an exciting lead on a sighting and a footprint on their final investigation.

The team travels to WI for the first time on the heels of recent bigfoot activity, enlisting help from locals to investigate reports. They take the final night investigation to new heights as they are stalked by bigfoots in the dark.

The team travels to Iowa to investigate Yellow River State Forest's history of reports. The local BFRO share stories around the campfire, and the team explores the park, leading to an epic final night, and a squatch on therm.

Water is key to life, but it's in short supply. The planet is getting warmer and soon there will be less water to go around. The animals fighting for freshwater are explored, including viscachas in Peru and hippos in Kenya.

The great plains and savannas are feeling the heat from climate change and out on the grasslands there will be less food and space for survival, which impacts the Iberian lynx in Spain and lions in Kenya.

Forest animals have an incredible home and their trees are nature's engines, filtering water, storing carbon and pumping out oxygen. But climate change is threatening their stability from the Amazon to Canada's Boreal forest.

Temperature is the key to life in a mountain environment, and climate change is forcing mountain animals to travel higher to escape the oppressive heat. Pikas in the Rocky Mountains and nursery frogs in Australia are featured.

Climate change has impacted the balance of life in the wetlands, and out in the marsh there's less water and food for survival, which affects magpie geese in Australia and the Key deer in Florida.

Oceans are getting warmer due to climate change, and rising sea temperatures are an invisible but deadly killer affecting corals of the Great Barrier Reef and tiger sharks along the coast of Australia.

Temperature is a key factor for survival at the Earth's poles, but the arctic is warming due to climate change and the animals affected include polar bears in Northern Canada and king penguins in the South Atlantic.

In 1976, a packed coach crashed into the Amazon killing 39 people. Some of the bodies had been so viciously mutilated by piranhas they could only be identified by their clothes. Extreme angler Jeremy Wade investigates the piranha.
