Brie Larson Eats a Rhino Beetle | Running Wild With Bear Grylls

So were you kind of adventurous when you were growing up, or-- I wanted to be Indiana Jones when I was younger, but then--

Really?

--I also was super shy.

And were you like, sporty?

No, not at all.

BEAR GRYLLS: So what, more geeky?

I was super geeky.

BEAR GRYLLS: [laughs] This is basically my audition for Indiana Jones. [laughs] OK. Let's get into this. Now this is mangrove swamp. This is the start of it. It's actually a pretty amazing ecosystem, because it's just so full of incredible, diverse wildlife.

Lot of crocs, by the way, you know, further into this stuff. But this is the start of the mangrove, and we need to be going this way. It's going to be fun, right? What's the worst that could happen?

Yeah, this is going to be many things. Fun is not going to be one of them.

OK. Let's do it. [music playing]

Whoa-ho-ho. This, as a survivalist, is good. God, look at the size of that one.

Oh, look-- [gasps] That's a rhino beetle grub, larvae. Look at that. There's another one. You get that one out.

Oh, my gosh. Good protein, good snack, this is.

BEAR GRYLLS (VOICEOVER): As a general rule, raw grubs are edible. They have more protein, pound for pound, than beef. And they are plentiful in dark, damp places all over the world. But it's critical that they're purged before consumption, in case they've eaten something poisonous to humans.

BEAR GRYLLS: So look, grab the head.

No.

And then you just twist the head, pull that off, and then all of that. [laughs] Your face, I love it.

What just fell out of it?

I think some really medieval guts. You squeezed his heart out.

Listen, that's many things, but that's not a heart.

I think that's his anal tract. [laughing]

Ew.

BEAR GRYLLS: [laughs] And then you're left with that, and that's all good. Good energy. Little skin.

Do you want me to go first, or do you want to go first?

• I'll do it with you.

• Oh, OK. Here we go. I don't think I got all the anal tract out, but what's the worst that could happen, right? Just adds the flavor.

OK, great. I just a beetle larva. I'd rather not explain what it tastes like.

Ugh. Doesn't taste very good.

No. But good energy.

Feel energized, I guess.

Yeah. I think I'm supposed to feel more energized than I do.

I think the cappuccinos work better.
