In Zambia's Luangwa Valley...

a future king was born.

From season, to season...

one year, to the next...

he embarked on a journey
towards greatness.

He already had the attitude
and behaved like royalty.

Gradually he became fearless.

Becoming stronger
with each fight...

more confident

slowly rising from the deep...

an old hippo bull.

The years have taken their toll.

His tired, cloudy eyes reflect
a brutal life hard-lived.

He has seen it all.

His maze of scars...

Skin-deep memories
from ancient battles.

But in his prime...

this once-invincible bull
chose a path of war.

This is the remarkable story
of his journey...

that led to the ultimate battle
that crowned him king.



A long, long time ago,
in Zambia's Luangwa Valley...

where a mighty river is home

to one of the largest
hippo populations in the world,

the dry season had just begun.

In the blistering heat, a hippo
pod was basking in the sun,

and one female had separated
herself from the others.

It was the day a future king
was born.

He took his first glimpse
of the outside world.

The little newcomer drew
unwanted attention.

His mother was well aware
of the danger.

She kept her calf close.

But the crocodiles weren't
her only concern.

A lion, in search of prey.

Her calf, a perfect target.

And this young male
was heading straight for them.

But something made him hesitate.

The river belonged
to another predator.

It gave her time
to hide the calf.

But the lion braved the waters.

While
focused on finding the calf,

the lion was facing
a protective mother.

His courageous mother
saved his life.

In those first few weeks,

his mother kept him separate
from the main pod.

This precious time together
was essential

in strengthening their bond.

Recognizing his mother
once they joined the pod

would be crucial for his safety.

He would rely on her protection
for years to come.

And then the big day arrived.

His mother led him
to the main pod.

He was ready to join his family.

Becoming part of the main pod
seemed to be a safe move

with all-'round protection.

But amongst these 3-ton giants,

the calf was
all the more vulnerable.

Explosions of aggression
are common amongst hippos.

But ironically,
it was his father

that was by far
the biggest threat.

When he went into battle
with an opponent,

razor-sharp tusks clashing,

their brute force would
crush anything in their way.

Calves often fall victim
to these brutal fights.

Thankfully his mother
was protective and caring.

But with the river shrinking
and the pod growing,

tension would only rise,

so becoming part of a crèche
provided a safe space.

The youngsters stayed
close together,

surrounded by a few
protective mothers.

They spent their days
basking in the sun,

with not a care in the world.

And that's when he got to meet
his new friends.

The oxpeckers.

Little birds
that removed parasites

and cleaned the hippos' wounds.

But they often made
things worse.

To many, they became a nuisance.

Every fresh wound
was a reason for battle.

They were out for blood.

Getting rid of them
was mission impossible.

Submerging was the only way.

And when the river
became too low,

water cannons
were brought to bear.

An effective way to send
a bird packing,

but they would always return.

Oxpeckers would be
his lifelong companions.

As this dry season progressed,

carmine bee-eaters
made their entrance.

With the river now low enough,
they were able to start nesting.

While the birds added a splash
of much-needed color

to the advancing drought,

the calf grew into
a more confident youngster.

He would stand his ground...

and took on his first battles.

He was learning to be bold.

Sparring sessions prepared him
for the fights

that were to come later in life.

And he would lean on his mother

to reach greater heights.

Heights he could still
only dream of.

He already had the attitude
and behaved like royalty.

Until the true king of beasts
arrived.

Being surrounded by lions

quickly brought him
back to reality.

His attitude faded
as fear took hold.

The river was their haven.

But the lioness could swim, too.

A calf his size is easy prey
for a lion.

The big cat was surrounded
by hippos.

Her snarls were intimidating.

But an adult hippo
could easily kill her.

In this river, she was
just as vulnerable

as he was on land.

The lioness made a daring move,
so close to the hippos.

her pride intently watching.

She might have made it
past the hippos,

but crocodiles
still lurked below.

From the safety of the pod,

the calf watched
the saga unfold.

The lioness was fortunate
to make it across alive.

As the Luangwa River
kept shrinking,

more and more hippos
congregated...

and fought over
every inch of space.

The cruel reality
of the drought hit hard.

A feast had begun.

Dead hippos attracted attention.

It was the calf's first time

to experience the dark side
of the dry season.

When the hippos suffered,
the crocodiles thrived.

With the river at its lowest,

the hippos desperately searched
for food and space.

The first blissful rain
finally arrived.

It brought relief
to everyone in the pod.

A moment to relax.

Even the calf's father
dropped his guard.

A moment a challenger
had been waiting for.

His father had to defend
his throne.

There could only be
one dominant bull.

It was an equal match.

A fight like this ended
in stalemate.

His father did some serious
damage to his opponent,

but the bull himself was nearing
the end of his reign.

The season had turned.

The Luangwa Valley transformed
into an emerald green paradise.

The calf had made it
through his first dry season,

and was now thriving,
with plenty of grass and space.

Making it this far
was a significant victory.

Many hippo calves don't survive
their first few months.

For him, the future
seemed promising.

Throughout
the different seasons,

the calf remained close
to his mother

and was mostly by her side.

Every time the rains returned,

it meant the end of hardship.

The cycle of the seasons

saw him grow ever bigger.

These periods of prosperity

made the youngster
more independent,

which encouraged him
to aim higher.

Throughout the years, the calf
grew into an adolescent,

gaining confidence and size.

He followed his mother
from one pod to the next,

and with his newfound bravado,

he spent most of his time
sparring with his peers.

Slowly his tusk force
grew bigger and sharper.

He was a king in the making.

Luangwa lay at his feet.

Having walked these paths
for centuries,

the hippos of Luangwa
know its secrets to survival.

His mother, too, had a lifetime
of experiences behind her.

She knew how to survive here,
even during the worst droughts.

But she was getting old
and frail,

and had not given birth
to any more calves.

So it was still
just the two of them.

Now as a subadult,
he no longer depended on her,

but would stay with his mother
for as long as he could.

Their bond seemed everlasting.

But then, as the dry season
reached its peak,

everything changed.

His mother...

prone and vulnerable.

She desperately tried
to make it back to the river,

but she had no strength left.

His mother was facing
a slow death.

She had reached the end
of her time.

The next morning,

the youngster stood by
helplessly.

His mother had died.

He threatened the lions that
surrounded her but was ignored.

Scavengers were circling.

There was nothing he could do.

He was frustrated and confused,
not knowing where to go.

Wandering around aimlessly,

he hadn't noticed the trap
he was walking into.

That was a close call.

He had no choice
but to leave his mother.

Every opportunist,
every predator...

all made the most of this feast.

From the river,
he became a spectator

to nature's primal display.

The cycle of life played out
right in front of him.

Each creature fought
for its right to feed,

its right to life.

Taking turns, predators
from both land and water

took full advantage
of the death of a giant.

His yawn was an outcry of
distress and desperation,

but displaying his tusks

was regarded as a direct
challenge by the dominant bull.

Before he realized
what he'd done,

the dominant bull attacked.

An excruciating grip
to oust him from the pod.

The punishment for
his unintended insolence

may have cost him his tail.

The message was clear.

He was no longer welcome.

He could never return.

The first night on his own.

He was used to feeding
in the dark,

but this night
was darker than usual.

Without his mother,
it felt more dangerous.

For good reason.

Lions hunt at night.

He was unsure of
their intentions.

This time, he wouldn't let them
come close.

The lions' hunt had begun.

Fortunately for him,

they killed an antelope.

He continued grazing...

but kept a close eye
on the lions.

Anyone in his way
was charged at.

Now he had to fend for himself.

The predators were in the middle
of a fierce battle.

Maybe best to make a run for it.

By daybreak,

the young bull was desperate
to get back to the river.

Having been evicted
from his pod,

he needed to find a new home.

The bull in charge of this pod
immediately noticed his arrival.

But the young bull was hoping
for acceptance.

The dominant bull was not
going to make it easy.

If he could show submission,

the bull might
allow him to stay.

An important lesson in life...

Giving in sometimes
gets you what you need.

Although the young bull
was now accepted by a new pod,

with this dry season persisting,

he was forced to search
for food in daytime.

There is a tree in South Luangwa

that blooms when the drought
is at its worst.

The fruit of the sausage tree.

Not long ago, his mother
had led him to this place.

A modest oasis
in the grip of the sun.

The African sausage tree,

known here as the tree of life.

The massive, solid fruit,
seemingly inedible,

is the secret to survival.

These fruits would help him get
through the toughest of times.

But eating the enormous sausages
was not all that easy,

especially for a grazer.

It required a special technique.

He had seen his mother
master the art.

Now it was his turn.

Another year had gone by.

And as always, the new wet
season brought salvation...

and new experiences.

A surprise
for the young hippo bull.

Elephants in his lagoon.

Such an intrusion drew a crowd.

And they weren't just after
an innocent swim.

A yawn was supposed
to be a threat...

but was perceived
as an invitation.

A game of hide-and-seek ensued

of gigantic proportions.

Usually hippos and elephants
stay out of each other's way.

But the elephants
deliberately gate-crashed

the hippos' pool party.

The elephants teamed up
to chase the hippos around.

But they were way out
of their depth.

How can a 3-ton giant vanish

just like that?

For once, the hippos
had the upper hand.

The plentiful wet seasons
are fleeting,

and the inevitable dry times
returned.

But even the worst droughts
would eventually

make space for the rains again.

Years passed by.

Nearly a decade later,

the subadult had turned
into an adult bull.

Together with a few
fellow bachelors,

he had found
a new home in a lagoon.

It wasn't deep,
but rolling helped

to keep their bodies
moisturized.

The muddy substance
formed the perfect sunscreen.

Life here was peaceful,
but it wouldn't last.

The rhythm of the seasons meant
change was the only constant.

A few months later,

the bull's lagoon had dried up.

Everyone else had left...

except for his constant
feathered companion.

But then he received
an unexpected visitor.

A leopard, searching for water.

But the sun had soaked it
all up.

There was nothing left
but cracked, dry earth.

There was no point in staying.

He needed food
and another place to live.

Hippos depend on water.

Desperate times were upon him.

Nighttime.

He knew where to go for food.

Now that he'd become
a large bull,

he visited the tree of life
more often.

Enjoying the fruit,
he was unaware

he was being watched.

An acquaintance from earlier,
also in search of food.

Unlike him, she preferred meat.

Silently,
she approached a target.

Recognizing the difference
between predators,

he knew, to him,
a leopard was harmless.

She paid no attention to him,

focused on her hunting.

His curiosity
got the better of him.

What was she up to?

Try staying unnoticed with
a giant herbivore on your tail.

Busted.

It turns out, hippos don't make
good hunting partners.

After the thrill of
the sabotaged hunt,

the bull made it
to the river by dawn.

Having lived in the lagoon
these previous months,

he was new here.

How best to make an entrance?

Subtle.

He stood on the edge
of a new phase of life.

And with daybreak...

came courage.

He arrived with a splash.

As the years went by,

the Luangwa Valley
remained his home.

Another wet season.

The bull had grown
in confidence and stature.

He was no longer willing
to remain submissive.

Now in possession
of much bigger armory,

he showed off
his impressive tusks

and was eager
to put them to the test.

A brief challenge,
with no real winner.

But it was a good start.

His future seemed
all the more promising.

From season, to season...

one year, to the next...

he embarked on a journey
towards greatness.

His shadow reflected
the size of his ambition.

His wounds,
signs of his bravery.

Whichever path he chose,

it would ultimately
lead him to battle.

He was growing into a formidable
contender to the throne...

...though he was still no match
for a dominant bull.

Gradually he became fearless.

With each step, he got a little
closer to the end game.

Becoming stronger
with each fight...

more confident
with each journey.

And whenever he was challenged,

he'd respond in kind,
audacious and bold.

He was on the cusp of supremacy.

And then, one fine morning,

his transformation was complete.

He radiated self-assurance.

The potential of victory
drove him forward.

A fully grown, impressive bull
entered the arena.

The dominant bull immediately
responded to his arrogance.

There was no stopping him.

They sized each other up.

He hadn't fought an experienced
bull like this before,

but he had no intention
of backing down.

In hippo warfare, the first act
was a show of armor.

He blatantly claimed
the territory already.

A red rag to a bull.

His opponent took the bait.

On second thoughts,
he may have overplayed his hand.

The dominant bull was merciless.

He tried to escape...

but the dominant bull
was hot on his heals.

But in the face of sustained
conflict, he found his courage.

Once those tusks clashed,

they were both in
for a long battle.

He was getting the upper hand,

forcing his opponent to retreat
towards the edge of the bank.

But the dominant bull
wasn't giving up that easily.

Both bloodied and exhausted,

the older bull
eventually admitted defeat.

And that is how he became king.

As the dominant bull,
he reigned for many years.

He was admired by his calves...

and always surrounded
by his harem of females.

He was a protective
and successful ruler.

His fortunes rose and fell
throughout his supremacy.

But now his fighting days
are over.

He is 35 years old,

and no longer
the ruler of a hippo pod.

But it's been a life filled
with battles lost and won.

A life whose unrivaled legacy
is forever reflected

in the waters of Luangwa.
