concentration.
Back out in the swamp, someone had just let out a terrified, ear-splitting scream.
Zac raced out of the cave and back towards the swamp. He reached the edge of the water and saw right away who had been screaming.
It was Caz. She was standing aboard her little hovercraft, cracking her Electromagnetic Whip at a massive crocodile.
Caz brought the whip down again and again, sending sparks flying. But the crocodile didn’t even seem to notice that it was being hit.
The hovercraft rocked back and forth, and Zac could see that it was only a matter of time before the croc knocked Caz right into the water.
Zac sighed. He knew what he had to do.
He jumped back into the swamp and began wading out. Towards the crocodile.
But as he got closer, he realised that it wasn’t a real crocodile at all. Instead of scales, the croc was covered in grey steel plating. Instead of eyes, two red lights blinked menacingly in Caz’s direction.
It was a robotic crocodile! It must have been planted there by Professor Voler.
As if the real animals in this place aren’t bad enough! thought Zac, remembering the eel.
He crept up behind the robocodile, trying to keep from being seen. Zac remembered something he’d seen on Leon’s favourite nature show, Creepy Creatures.
Zac leapt up onto the robocodile’s back, just as it took another lunge at Caz.
The robocodile’s mouth snapped shut. Zac grabbed onto the closed jaws and held on tight.
For a second he thought his plan had worked. But then the robocodile snapped its mouth open again, flipped Zac over and threw him into the swamp.
I guess that rule only works for real crocodiles, thought Zac, getting to his feet. He decided to switch on his Electro-Armour just to be safe.
Caz cowered on the hovercraft, but the robocodile had already started swimming towards Zac.
Zac turned and ran through the shallow water, but his feet kept slipping into the mud, slowing him down. In seconds, the robocodile was right on top of him. It stretched its mouth wide. Looking up, Zac saw row after row of razor-sharp steel teeth.
Uh-oh, he thought, trying to dart out of the way. But the robocodile lunged right for him. Its mechanical jaws came down on top of Zac, right across his chest.
Luckily, Zac’s arms were up in the air, and the robocodile’s metal teeth crunched down hard on his Electro-Armour.
The armour sent a surge of electricity into the robocodile’s mouth. The croc shot up into the air, twisting and sparking. Zac could see that its systems had been fried instantly.
Zac dived out of the way as the robocodile came crashing into the water, completely destroyed.
Zac stood up and paddled over to Caz’s hovercraft.
‘I thought you were done for,’ said Caz, sounding almost disappointed that the croc hadn’t finished him off. ‘He bit you straight across the chest! How’d you survive that?’
Zac lifted up his shirt to reveal the Electro-Armour hiding underneath.
‘Hey!’ Caz protested.‘How come you’ve got armour?’
‘I wouldn’t be complaining if I were you,’ said Zac. ‘This armour just saved your life!’
‘Well, I’m fine now,’ said Caz, crossing her arms. ‘So you can get out of here.’
But when Zac looked down and saw the time, he knew it wasn’t going to be that simple.
There were only two hours left! He cringed as he realised what he was going to have to do next.
‘Well?’ said Caz. ‘What are you waiting for? Get lost!’
‘No,’ said Zac. ‘Let me onto that hovercraft.’
‘Yeah, right,’ Caz laughed.
‘I know where the plastic toad is hidden,’ said Zac. ‘But we’re going to have to go together.’
‘I’m not going anywhere with you, Rock Star,’ Caz growled.
‘You think I want to be stuck with you ?’ said Zac. ‘In two hours, Voler’s going to fly off and leave us both behind. You can’t even stay alive in the daytime without my help. Do you really want to be stuck here at night?’
‘No-one asked you to
