I'm hoping that we can make a dive to learn more about the hippos environment without coming face to face with one.

I'm going in with Brad on my underwater cameraman Johnny.

Brad's wife, Andi, and dive supervisor Sarah Connor will be keeping a lookout.

Topside, we search the lagoon in case another loan.

Hippos lucking, it seems clear, but we can't rule out.

Crocodiles begin the deltas because there's been the potential of crocodiles.

They could be there if we encounter a crocodile.

There's obviously an area that, but so you don't want to push to crash into it.

Whatever you do, don't bump it by mistake or touch it right.

Let's get going.

Okay, yeah, Wait.

In case a hippo does appear, Brad's right hand man is loading up the elephant gun they keep on.

The boat is a last resort, but soft sand of the riverbed holds clues.

Tracks.

Hippos don't actually swim.

They run along the bottom.

I got you.

Sorry.

Hearing go.

Andy's dived with crocs.

Hippos are far more savage.

Proposition.

I think bread could see that the on papers they pop their heads up by now, so it's potentially precarious.

But they well under control.

You know, there's no doctor would not support the head.

You just can't take that chance.

Because if that hippo is a dangerous hip, then you're gonna be dead.

So you're either gonna have a fabulous time where you're gonna be did it for me.

Those statistics just don't compelling something with a wild hippos.

Unbelievably dangerous because it's so unpredictable in that hippo decides that it doesn't like the end of attack.

Absolutely.

There's nothing you could do.

You can never move as fast as they can.

I'm sorry.

I shouldn't say that on camera, but seriously, our fate is in the lap of the gods.

If the hippo decides to attack, then we've had it.

You're right.

All right, Lawrence, take the boat around this way to take the high ground, and he brings the boat over to pick us up back.

It was It's pretty shocking.

Um, we could swim straight into a Hitler on the buses, and as soon as it came to within a few meters of May, she just turned side on and headed straight out down that way.

That was really frightening just the fact that she could be in here and underwater without any sign of it whatsoever from the surface, Um, just shows that this place is peppered with hippos with all kinds of wonderful things.

But that was really, really frightening.

She might have had a look at us.

I don't know.

I don't know what you're saying now.

They just move away.

We've just become some of the very, very few people in the whole world who have ever been in the water and swam with hippos.

Nothing dive with sharks, crocodiles, whales, all sorts of other things.

But my heart rate is never gonna buy that before, when that just came out of the brown.

I just don't Don't don't, don't, don't, don't.

It's not a female.

It's a young bull and he's unhappy to have trespass is in his pool.

He's displaying warning signals to let us know that was all he pay.

I think we should just move away gently and just let him be the hippos only 30 meters away and could cover that in seconds.

We have to leave now.

I think he's coming to the surface trying to figure out What escape Bridges?

Spencer.

We just need to move out of giving this space.

That was a close as I ever want to be a hit.

But that tantalizing glimpse has made me more determined than ever to understand these intriguing animals.
