EXCLUSIVE: Alaskan bears are the latest reality stars in new show 'Hungry Games.' See a clip

Alaskan bears are the main stars in a new survival reality show.

Peacock’s “The Hungry Games: Alaska’s Big Bear Challenge” focuses on the bears of the Katmai National Park as they get ready for winter hibernation, all through the lens of a playful competition.

In TODAY’s exclusive clip, which aired July 3, mama bear Boldface attempts to cross a river with her three young cubs: Bandit, Raccoon and Scamp.

Boldface first tests the current before signaling to her pups to follow suit, narrator and actor Rhys Darby says.

“Now she’s calling for them. That means they’re going to have to swim for it,” Darby narrates, as the three cubs enter the way. “Boldface is waiting for them about halfway across the river. If they can swim to her, she can carry them the rest of the way.”

In “The Hungry Games,” over the course of 150 days, the bears “battle the elements — and each other — using brains and brawn to consume three million calories and gain up to 200 pounds in Nature’s real-life survival show,” the synopsis reads.

Unaware that their every move is being filmed to be enjoyed by audiences everywhere, the show tracks the bears' progress while Darby narrates and shares fascinating facts about their behavior.

The brown bears of Katmai National Park in Alaska are famous in their own right. Every fall, they gather at Brooks Falls to catch and eat sockeye salmon, packing on the pounds ahead of their winter hibernation. Their popularity has resulted in the annual voting contest dubbed Fat Bear Week, where people vote for their favorite chunkiest bear.

Last year, 128 Grazer, a mama bear who arrived at Brooks Falls in 2005 and has raised two litters of cubs, was crowned the winner.

“The Hungry Games: Alaska’s Big Bear Challenge,” which is produced by Ample Entertainment, premieres July 11 on Peacock. (Peacock a part of TODAY.com’s parent company, NBCUniversal.)
