“So you’re saying it’s some mutated form of this species?” Nate asked.
“I thought so at first. It looks almost like a tadpole whose growth was arrested at the stage where gills were still present and only its hind legs had formed. But as I dissected further, I became less convinced. First, and most obvious, is that its size is way out of proportion. This thing must weigh close to five pounds. Monstrously gigantic for even the largest species of dart frog.”
Manny rolled the dissected creature over and pointed to its eyes and teeth. “Additionally, its skull structure is all misshapen. Rather than flattened horizontally like a frog’s, the cranium is flattened vertically, more like a fish’s. In fact, the skull conformation, jaw, and teeth are almost identical in size and shape to a common Amazonian river predator—Serrasalmus rhombeus.” Manny glanced up from his handiwork. “The black piranha.”
Kelly leaned away. “That’s impossible.”
“If this thing weren’t right in front of me, I’d agree.” Manny sat back. “I’ve worked with Amazonian species all my life, and I’ve seen nothing like it. A true chimera. A single creature that shares the biological features of both frog and fish.”
Nate eyed the creature. “How could that be?”
Manny shook his head. “I don’t know. But how does a man regenerate a limb? I think the presence of such a chimera suggests we’re on the right trail. Something is out there, something your father’s expedition discovered, something with a distinct mutating ability.”
Nate stared at the dissected ruins. What the hell was out there?
A call arose from Private Carrera. Her sentry post faced the northern slope of the knoll. “They’re on the move again!”
Nate straightened. The rustling from her side of the forest had grown louder. It sounded as if the entire jungle were stirring.
Carrera flamed the lower slope. Her fiery jets pushed back the darkness. Reflected in the fire were hundreds of tiny eyes, covering both the forest floor and the trees. One of the creatures sprang from its perch on the limb of a palm tree and bounded into the fire zone. There was a short chatter of automatic rifle fire, and the creature was shredded to a bloody mush.
“Everybody back!” Carrera called. “They’re coming!”
From the trees and underbrush, small bodies started to leap and bound toward them, oblivious to the fire and bullets. The creatures were determined to overrun them with their sheer numbers.
Nate flashed back on the Indian massacre site. It was happening all over again. He swung his shotgun from his shoulder, aimed, and blasted a creature in midair as it leaped from a branch over Carrera’s head. Gobbets of flesh rained down.
As a group, they were forced to vacate the knoll’s summit and retreat down the southern face. Gunfire and flames lit the night. Flashlights danced, making every shadow shift and jerk.
Leading the charge down the southern slope, Corporal Okamoto swathed jets of fire before them. “It still looks clear this way!” he called out.
Nate risked a peek his way. Distantly through the forest, he could make out the other fork of the stream below as it swept around the southern flank of the hill.
“Why aren’t any of the creatures on this side of the hill?” Anna asked, her face flushed.
Zane answered, his eyes wide as he kept glancing behind him. “They probably rallied all their numbers on the far side for this final assault.”
Nate stared toward the stream below. It was wide, smooth, and quiet, but he knew better. He remembered the large capybara rodent flushed from the forest and racing along the river, where it was set upon by the predators. “They’re herding us,” he mumbled.
“What?” Kelly asked.
“They want us close to the water. The pack is driving us to the river.”
Manny heard him. “I think Nate’s right. Despite their ability to move on land for short distances, they’re basically aquatic. They’d want their meal as close to water as possible before taking it down.”
Kelly looked behind her to the line of Rangers flaming and firing along their back trail. “What choice do we have?”
Down the slope, Okamoto slowed as they neared the river, clearly suspicious of the water, too. The corporal turned to Captain Waxman behind him. “Sir, I’ll try to cross first. Like last time.”
Waxman nodded. “Careful, corporal.”
Okamoto headed for the stream.
“No!” Nate called. “I’m sure it’s a trap.”
Okamoto glanced to him, then to his captain, who waved him forward again.
“We have to get off this island,” Waxman said.
“Wait,” Manny said, stepping forward, his voice pained. “I…I can send Tor-tor instead.”
The others were now all gathered around.
Waxman stared at the jaguar, then nodded. “Do it.”
Manny guided his jaguar toward the dark waters.
Nate’s mind spun. It was suicide to enter those waters. He knew this as certainly as he knew the sun would rise tomorrow. But Waxman was right. They had to find a way across. He ran through various scenarios in his head.
A rope bridge over the stream. He quickly ruled that out. Even if they could somehow string a bridge up, the aquatic creatures were adept at leaping great heights. They’d all just be so much bait strung on a line.
Maybe grenades tossed in the water to stun them. But the stream was long. Any creatures killed by the concussion would be quickly replaced by those upstream. They would sweep down the sluggish current, attacking the team as they tried to rush across. No, what was needed was something that could strip this entire fork of the creatures—but what could do that?
Then it dawned on him. He had seen the answer demonstrated just a few days back.
By now, Manny and Tor-tor were only a couple of yards from the stream. Okamoto was with them, flames lighting the way.
“Wait!” Nate called. “I have an idea!”
Manny paused.
“What?” Waxman asked.
“According to Manny, these things are basically fish.”
“So?”
Nate ignored the captain’s glare and turned to Kouwe. “You have powdered ayaeya vine in your medicine kit, don’t you?”
“Certainly, but what—?” Then the professor’s eyes grew rounder with understanding. “Brilliant, Nate. I should’ve thought of that.”
“What?” Waxman asked, growing frustrated.
Behind them, up the slope, the line of Rangers held the creatures momentarily at bay with rifles and fire. Down slope, Okamoto stood ready by the river.
