- [Narrator] Yoko's still got a coconut. With a surprising burst of energy, Beni goes after him again. The commotion attracts the attention of another older female, Reren. Who comes in with the heavy artillery. At forest school, the scene is all set for Mulyono's snake awareness lesson. (speaking in foreign language) - [Narrator] The call has
gone out for milk time. And the babysitters move into position. With 160 snake species
in Borneo, this lesson is critical in teaching the students that snakes are to be feared. (speaking in foreign language) - [Narrator] Everything is ready. But no one's taking the bait. So the babysitters help the lesson along. (screaming) (suspenseful atmosphere music) They give it their all. To reinforce the fear factor. Everyone remembers their training and flees to the safety of the trees. But this time the tree isn't safe. Luckily, no one is hurt. As the orangutans have learned how to react when a tree breaks. Which is common in the forest. Mulyono is especially impressed by Leta and Russini's acting performances. As Mulyono leaves, the friends comfort each other in the aftermath of a lesson they'll
hopefully never forget. Milk time brings everyone together. Including ever hopeful Beni. He's still on a strict diet as he's twice the weight of
classmates his own age. Due to his insatiable appetite. Six months ago, Beni discovered the secret stash of banana mountain. - Beni! Ben! - [Narrator] Quick
action by babysitter Sri stopped him doing too
much damage to his diet. (speaking in foreign language) - [Narrator] And his health. Much to his annoyance. Beni's diet is for his own good. But all he knows is that yet again everyone gets a milk drink. Except him. Babysitter Merni has a cunning plan, however, to stop him feeling left out. Without breaking his diet. (speaking in foreign language) - [Narrator] Beni finally gets his turn. Although it looks as though he suspects he's not getting the real deal. His weight loss plan is proving
difficult for everybody. He's a clever food thief. But his real forte is his begging routine. This face is hard to resist. But with his weight still
hovering around 66 pounds, babysitter Icha isn't going to be moved. Only healthy greens are on offer. Much to Beni's disgust. (speaking in foreign language) Even Shiro's example can't persuade this banana-loving boy to change his ways. In forest school group one, today's workshop is nest building. So far, the students have learned the fundamentals on the
safety of the ground. Today the two to three
year olds will learn how to construct nests in the branches. Meryl's up first. She watches as Leta lays the framework. But doesn't seem terribly impressed. She takes a more laid back approach. Leta tries to keep Meryl engaged. But she exits the lesson. Taking half the nest with her. Perhaps three year old Fathia
will be a better student. She piles the leaves up. Layer upon layer. Just as she saw her babysitter doing. Flattening it out is the fun part. Being able to eat your bedding is one advantage to being an orangutan. Pillow fight anyone? Finally, she decides her nest is complete. Fathia has made great strides today. While Meryl is falling behind. Borneo is home to around
160 species of snake. Many of them venomous. Including this keeled
pit viper that strayed into the compound from
the surrounding forest. The staff quickly captured the intruder. And Mulyono has decided it's time for group four's lesson
in snake awareness. Mulyono doesn't usually
attend forest school classes. So as soon as they spot him. The students can tell this
is no ordinary lesson. Jumbo and Yoko try to scare him off. Liti, Lanting, and Cinta are the bravest. And then little Eric joins
Cinta for a closer look. (suspenseful atmosphere music) This snake is rubber, but it looks real enough to the orangutans. This response is just
what Mulyono hoped for. Terrorizing these
youngsters may look mean, but one day this lesson
could save their lives. At the new arrivals
quarantine class, tiny tot Topan is about to
receive her first lesson. Baby orangutans start learning from their mothers on day one. So it's never too early
for a gentle tutorial. Orangutans mainly stay hydrated from all the fruit they eat. But they do use tools to collect water. Topan isn't keen. So Mia decides to try
something a bit more exciting. Borneo is a biodiversity hotspot for carnivorous pitcher plants. The fluid inside traps insects that provide nutrients for the plants. And can also serve as a
great thirst quencher. Topan, however, has a different priority. It's mid-morning at the
group three classroom. And already the temperature is well over 90 degrees Fahrenheit. The babysitters have brought basketloads of papaya leaves for
a healthy snack today. But one of the students is planning an alternative use for his leaf. Five year old Otan is affectionately known as the fluffy ninja. He's small for his age,
inventive, and curious. When there was something terrifying under the sack at snake school. Otan accidentally revealed it. Today, he's going to wear his leaf. It's not a fashion statement though. It's sheltering him from the hot sun. As is often the case in jungle school, Otan's experiment catches on. Valentino copies. (farting) And so does Junior. These leaves were supposed to be a snack. Turning them into sun hats shows what creative thinkers orangutans are. And of course they imitate each other. The trend spreads like wildfire. Valentino is first to take
things to another level. Hat stealing. In the wild, young
orangutans learn most skills through imitating their mothers. Here there are many variations on what the orphan students can
learn from each other. Valentino remembers that you can actually eat these leaves as well. Cinta, never one to follow the crowd, uses hers as a plate to
catch her turnip scraps. Beni turns up. And seems unimpressed by Valentino's look. The new Beni is way too mature for this. He's off the climb a tree. An activity usually too energetic for this plump orangutan. But he's giving it a go. Compared with the exertions
of his classmates, Beni's style is low key. All that clambering and vine swinging? Way too much effort. It's the last lesson at
forest school for the day. And some older students have come to visit their friends in group two. Valentino, Yutris, and
Madara join their older idol Cinta on an adventure
through the ferns. And there's a surprise waiting for them. (tense atmosphere music) There's something not right. Penti reassures the youngsters. But Cinta has a suspicion
as to what this might be. Bravely, she takes the lead. Four year old Otan arrived
late to the fear fest. And he thinks this sack looks good. Just in time, technici Mulyono comes to the rescue and beats his special rubber teaching aid to death. The group two kids have never had snake awareness class before. And today they responded perfectly. In primates, recognition
of snakes is instinctive. But fear of snakes is learned. Which is why Mulyono tours this lesson around the forest school group. It's a lesson they won't forget. At the group one
classroom, the babysitters have a plan for the flooded pool. To teach a new lesson in food gathering. Vegetables on stilts are a genius take on the famous fruit kebab,
designed to encourage students to master pond
foraging in the wet season. Malika gets it. Extra support from Leta
gives Malika the confidence to try this new step
towards her wild future. Now it's Timpah's turn for a lesson. She's always been a little water baby. Leta shows Timpah how to scoop water. She watches intently. But she can't quite grasp. How does one hold water? Just as she's had enough. She has a breakthrough. Figuring out how to use
a tool to hold water is a simple but useful concept that both humans and primates need to learn. Leta is very proud of her little student. These two share a true bond and Timpah isn't shy about her affections. Over at jungle school, forest groups two and three are taking class together. Today's challenge is
to master the two stage process of opening a coconut. First husking. Then nut cracking to access the sweet milk and the meat. Four year old Yoko is a group three student and he's got this down. His secret is to grip with hands and feet. Yoko's skill attracts a spectator. Beni loves coconuts as much as bananas. But he usually relies on
his babysitter to open them. Beni reverts back to an old habit. He's not really a bully. Just a very hungry food thief. Nine-year-old Rinto
turns up from group five to police this coconut conflict. Rinto decides Beni should
have no coconut at all. Nope, not getting this one either. Poor Beni. All he's left with is a
pile of sodden greens. It's not fair. Yoko's still got a coconut. With a surprising burst of energy, Beni goes after him again. The commotion attracts the attention of another older female, Reren. Who comes in with the heavy artillery. She wastes no time in punishing Beni. Things are getting out of hand. The delivery of more
coconuts ends the brawl. Beni's left with just an empty husk. And his low social status. He's not impressed. First lesson of the day
is boiyo, or fruit time. (speaking in foreign language) - [Narrator] Orangutans naturally spend up to six hours a day foraging for food. So breakfast doubles as a
perfect learning opportunity. (speaking in foreign language) - [Narrator] This morning's
lesson is in coconut cracking. Orangutans learn from example, so their caregiver shows
them how it's done. Mumut, A little male,
catches on immediately. While Valentino has a more
interpretive approach. With his distinctive pale belly stripe, Valentino is the claws clown
of forest school group one. What he lacks in technique he
makes up for in exuberance. But when the puzzle
proves too hot to crack, Valentino does exactly what he would do if he was in the wild Asks mom for help. Valentino was found alone in a forest as a baby after his mum was killed. Babysitter Leta is
currently his foster mother and she knows Valentino
must learn to do this on his own if he's to ever
graduate from jungle school. Nearby, the students of forest group two are incrementally more skillful. It's not so much age that divides groups one and two, but ability. Little Meryl has learned
how to husk her coconut. So she can enjoy the sweet milk. But not for long. Opportunistic Valentino
moves in to "share". He may not be the best
at coconut cracking, but learning how to reap
the rewards of other's hard work could be an
excellent survival skill. Three year old Beni has a
more laid back approach. He's exercising his jaws as his powerful teeth scrape the coconut shell. But there's not a lot of
other energy being exerted. He doesn't even flinch as Meryl helps herself to his leftovers. Little does Beni know that his expanding girth hasn't gone unnoticed. And he's about to be put on a diet. (gentle mood music)
