got a glimpse of cold reptilian eyes and a scaly snout edging towards them.
âCrocodile!â gasped Ben, pulling Zoe back. âWe have to get off the ground â now!â
âBut how?â Zoe looked round wildly.
âThereâll be a ladder up to the platform.â Ben stumbled through the ferns to reach the numbered trunk. Zoe was close on his heels. Behind her the ferns swayed and flattened as the crocodile followed.
Ben leapt up the first rungs of the wooden ladder. He reached down and grabbed Zoeâs hand, hauling her up to safety just as the crocodile launched itself at the base of the tree, snapping at the empty air beneath her feet.
âThat was close!â breathed his sister, scrambling up as high as she could. âI thought we were safe with our scent dispersers on.â
âCrocs have really acute hearing,â Ben told her, as he looked down at the enormous scaly creature that was still searching for its prey. âWe werenât exactly silent back there. Did you know,â he went on, as they climbed towards the platform, âthe saltwater crocodile can grow up to seven metres long?â
âFascinating,â panted Zoe, following on behind. âPlenty of room inside for a couple of kids then!â
At last they were on the platform. Down below they could see the distant shape of their attacker sliding back towards the dark sweep of the river that lay beyond the trees.
âThis will be a good place to try the call,â said Ben.
He pulled out his BUG and pressed some buttons. A loud chirruping noise filled the air and echoed far into the trees.
âIt would have been better to do this in the day when Kawan was awake,â said Zoe.
âWeâve got no choice,â Ben replied. âAnd Iâm sure heâll forgive us if it means he comes home.â
They sat as still as they could, carefully scanning the area through their goggles.
âFruit bats, otters and one or two monkeys,â reported Zoe. âI think they were silvered langurs. No orang-utans.â
Ben played the call again and again.
âLooks like weâre going to be unlucky,â he said at last. âPerhaps we should be making our way back ââ
He stopped. There was a rustling in the branches above their heads, followed by a loud chomping sound. Zoe quickly held out her BUG towards it to analyse the sound. âItâs an orang-utan!â she whispered.
âIâve read about their vocalisations,â said Ben. âThat sound means it feels threatened.â
âKeep still then,â said Zoe. âIt has to be Kawan, doesnât it? Heâs responded to the call. And after all weâre in his territory so none of the others would dare to be here.â
âGoggles on zoom,â Ben reminded her, adjusting his as he spoke.
âWow!â murmured Zoe. âHeâs right above our heads.â
A dark shape was stealing through the high branches.
Ben wriggled round and held his BUG above the leaves, activating its camera function. âGot a photo,â he whispered. They peered down at the screen. The face of a familiar-looking young orang-utan stared back at them. He had a distinctive tuft of hair sticking up on one side of his head, just like theyâd seen in the film.
âAwesome!â breathed Ben. âIt is Kawan!â
CHAPTER
SIX
The young orang-utan sat in the branches above their heads, gazing at Ben and Zoe, his eyes flickering nervously.
âIâve got a rusk in my backpack,â Zoe said quietly. âLetâs see if we can tempt him down and make him feel safe in his territory again.â
âMatâs going to be so happy,â said Ben.
Moving in ultra slow motion, Zoe stood up and held the rusk above her head.
Kawan began to swing gracefully down from branch to branch. He waited just out of reach, hanging from one long, shaggy arm and gazing around as if searching for
