Survivor 47 tribes and first challenge revealed in new sneak peek videos

Every Monday during the new Survivor season, you can expect to see a sneak peek at what's to come in the upcoming episode. Well, Survivor 47 premieres on Wednesday, Sept. 18, which means CBS just shared new sneak peeks at the season premiere on YouTube!

The season premiere is called "One Glorious and Perfect Episode." Okay, okay, okay.

There are two new sneak peeks for fans to watch right now. In the first sneak peek, Jeff welcomes to the new Survivor 47 cast to the beach and splits them into the three tribes. He also reveals what those tribes will be called.

In the second sneak peek, we get a preview of the first reward challenge!

Survivor 47 tribes revealed

In the first clip, Jeff Probst welcomes the cast to the beach and reveals the names of the tribes. We found out the names of the tribes and were able to figure out which cast members were on each tribe.

First, Jeff introduces the Tuku tribe. They're wearing the blue buffs. The Tuku tribe consists of Gabe Ortis, TK Foster, Sue Smey, Kyle Ostwald, Tiyana Hallums, and Caroline Vidmar.

Jeff moves on to the tribe in the middle, the Lavo tribe, wearing the red buffs. On the Lavo tribe, you'll find Teeny Chirichillo, Aysha Welch, Genevieve Mushaluk, Rome Cooney, Kishan Patel, and Sol Yi.

Last but not least, Jeff introduces the Gata tribe, wearing the yellow buffs. You'll find Jon Lovett, Sierra Wright, Sam Phalen, Anika Dhar, and Andy Rueda.

Jeff also speaks with Gabe Ortis of the Tuku tribe and asks about the role Gabe plays in his community.

"I mean, when it comes to work, I'm a grinder, man," Gabe tells Jeff. "I try to lead by example, and I've had to be the guy that says, 'I'm just as tired as you are, but if I've got energy to keep going, I know for sure you have got energy to keep going.'"

Jeff, then, talks to Teeny of the Lavo tribe, who despite her western, "scarecrow" pants, is a proud New Jerseyan.

Survivor 47 preview of the first reward challenge

As you'll recall, the new seasons of the New Era of Survivor always begin with a reward challenge for supplies right when the tribes make it to the beach. It's a bonding experience for the tribe, and it's an introduction for the players to learn what it's going to take to be successful in challenges. It's usually a pretty brutal challenge, and that trend looks to continue in Survivor 47.

In the clip, we get to see Jeff send out the players for the first reward challenge, and they must crawl under a net and through a mud pit. It's a metaphor, according to Probst.

"We're going out in pairs to get through that mud," Probst says. "That mud is birthing you into Survivor right there."

Based on the clip, it looks like Kyle Ostwald of the Tuku tribe finishes first and races through the course to what looks like giant puzzle pieces that they'll have to bring back to the tribe or solve in the jungle. We'll see on Wednesday night!

There is a new twist for Survivor 47. After this challenge, the winning tribe gets supplies to go build a shelter and boil water. The two losing tribes must compete in another challenge, which was previously called Sweat vs. Savvy, but that's out, according to Probst.

This season, they're trying something new, more exciting, and more fun. Again, we'll have to wait and see what happens in the season premiere, but we can't wait!
