Back with the other Riders, they were still trying to dig out the entrance. But the rocks were proving to be too heavy.

"Ugh. We'll never out of here at this rate." Heather panted.

"It only Meatlug were here." Fishlegs said.

"We have to try, Hiccup might be in trouble." Said Astrid.

"Claire is there another wa-" Heather was cut short when a trip line on the wall shook and a bell rang.

"Something's coming." Said Claire.

"Where does that tunnel lead?" Snotlout pointed to the tunnel.

"It connects to a underground..." Claire then heard a sound inside the tunnel. "Cavern tunnel system."

Everyone then everyone went to the tunnel looking inside, but it was dark and Fishlegs begins to panicked.

"It's the Legendary Creature, it's the Legendary Creature." Fishlegs quivered. "It's the Legendary Creature, guys! It's the Legendary Creature, it's the Legendary Creature, it's the Legendary Creature!"

"Stop! It's not the Legendary Creature." Heather tried to assured.

"Probably." Claire said.

"Probably?" Fishlegs questioned.

Then suddenly, lava started pouring through the roof and ceiling.

"Lava! Lava! Lava! Lava!" Fishlegs panicked.

"Deep breathes, Fishlegs." Astrid tried to calm him down.

Then they heard something as they turned and saw a silhouette inside the tunnel when some lava pour in. They back up and got pass the dripping lava, then the creature came into the light and revealed itself a mid sized predatory dinosaur called Baryonyx.

And then the Baryonyx roars, causing Fishlegs and Snotlout screaming and held on to each other.

"See?! Not a Legendary Creature!" Claire said.

"HOW IS THIS BETTER?!" Fishlegs screamed.

Then the Baryonyx came out of the tunnel, and roars as it approaches them. But only to get a drip of lava dropping on his head. It then cringed back and growls in pain.

Knowing that the lava will give them some protection, but not for long.

"Claire! What do we do?!" Fishlegs yelled frantically. "What do we do?!"

Then Claire saw the emergency ladder she has at the corner. In case if something happen. She quickly went to it and tries pull it loose, but it wouldn't budge.

"It's stuck!" She looked back. "CHAIR!"

They quickly saw a chair near them, and the Baryonyx tried to snatch one of them. But the lava stop it.

Heather was the first to act and grabs the chair. Then the Baryonyx clamps it's jaws on the chair's back, and now was in a tug of war. It lasted till a stream of lava hits the dinosaur's neck.

The chair was then quickly place under the ladder as Claire was the first climb. And soon, everyone went up as Heather covered the back.

"Come on!" Claire said. "Let's go!"

As soon as everyone was up, Heather begins to climb up.

"Come on, Heather!" Claire now at the top and begins to open the hatch.

"WE MADE IT!" Fishlegs shouted happily. "YEAH!"

Then suddenly, as if he jinx it. the lower ladder now comes lose, and drops onto the ground. And Heather is now totally exposed, and the Baryonyx now managed to slip pass the lava looks curiously at that. Heather froze and looks back behind her.

"Uh... Hi" She said nervously.

Then the Baryonyx roared at her, and Heather quickly climb up the ladder as the dinosaur went after her. She managed to get pass the tunnel, but the Baryonyx slip it's crocodile like snout through the shoot. And it's teeth caught the side of her boot, but quickly pulls free.

"Come on! Come on!" Astrid shouted as Claire tries to get the hatch open.

Then the Baryonyx roared causing everyone to scream. And then, Claire finally got the latch loose.

"Yes! Go, go, go, go!" Fishlegs frantically.

Claire lifts the hatch open, and everyone quickly climbs out. With the Baryonyx snapping it's jaws after them.

As soon as Heather was out, They immediately closed the hatch after a struggle when the tip of the Bary's snout was out. But the quickly closed it, and Claire turns the latch locking it.

But there was no time to rest.

Then Fishlegs saw something with great concern.

"Guys!" Fishlegs called not peeling his eyes off it.

Everyone then looked where Fishlegs was looking.

"Holy...!" Claire panicked.

The mountain near them which is the volcano lets out an explosion and begins to erupt. And then watched as a lava bomb soars through the sky like a meteor, and crashes somewhere behind a treeline.

"RUN!"

They looked behind and saw Hiccup running out of the forest. And there were some Compys near him.

"RUN!" Hiccup shouted again.

In the trees behind, some shook as approaching bellows and roars were heard. They immediately panicked knowing what's coming at them.

"RUN!"

Then bursting from the trees and smoke, came a stampede of dinosaurs and dragons. As 3 Gallimimus, a flying Skrill, a Razorwhip, 2 Stegosaurus, a Nadder, a Zippleback and an Apatosaurus and Singetail came running as fast their legs can take them.

"Holy...!" Heather panicked.

"RUN!" Astrid shouted.

They then quickly started running, and towards the nearby treeline.

"Run!" Hiccup shouted as he caught with them.

Then a fleeing Gallimimus and Speed Stinger ran past them, and a 2nd Gallimimus ran right between them. They soon entered the treeline, keeping one step ahead of the stampede. But they were far from safe, and a falling tree almost crushed Tuffnut. They soon ran out of the trees, and as 2 Apatosaurus, 2 Ankylosaurus, a Monstrous Nightmare, a BoneKnapper and an Armorwing ran out of the trees. Knocking some down, and the volcano lets out another explosion.

And a lava bomb hits the ground near them, and another as some Gallimimus and a pair of Speed Stingers and Velociraptors ran pass them. Then there was some logs and a large boulder ahead.

"Behind those logs!" Hiccup shouted. "Hurry! Hurry!"

They ran towards them as 2 Gallimimus leaped over them, and Fishlegs was the first to get over. An got behind the boulder as a Compy rushed pass him. And soon, the others joined him.

"We should be safe here!" Said Hiccup.

Then, on their right an Apatosaurus ran and tramples over a section of logs as they watched. And another did the same after an Ankylosaurus and Gallimimus ran by.

"You sure, man?!" Snotlout clinging to Fishlegs.

"Uh, it first. But now..." Hiccup unsure.

Everyone then held on to each a Brachiosaurus treads over another section on the right, and then an Ankylosaurus and Gronckle on the left. And soon after that, a Stegosaurus rams through the section on the right. As a Triceratops rams through on the left after a Razorwhip leaps over, and a Nadder busted through a branch sticking upwards. After 2 Gallimimus, an Ankylosaurus and a Slitherwing ran by. An Apatosaurus treads and flattens the last remaining left section of the log. And soon a Sinoceratops rams and destroys the last remaining section on the right, now the boulder is the only barrier left.

Then suddenly, a Quaken bumps into the boulder. Almost knocking them off their feet.

Realizing they have no other choice, but they have to leave.

"Come on!" Astrid yelled.

Then Hiccup froze and then a roar was heard, as they turned and saw a Carnotaurus.

A member of the Abelisaur Family, Carnotaurus is known for their horns over it's eyes. Which give them their name, which in fact means Meat Eating Bull. And it was about the same size as Stormfly or any other Nadder.

The Carnotaurus then begins to circle the riders. And lowers it's head near them, and a drop of sweat falls off Fishleg's face. Then the Carnotaur roars and appeared to have it's attention on something else. They looked and saw what it was looking at.

A Sinoceratops.

The predator charges as the Sinoceratops tries to make a run for it. But the Carnotaur caught it the Ceratopsian by the frill in it's jaws. And soon broke free as a fight broke lose.

The Sinoceratops charges and slams it's frill on the Carnotaurus, the Riders watched in amazed and concern. The Sinoceratops then shoves the Carnotaur off it's feet, and then flicked it's foot at the herbivore's face. And despite it's small arms, it quickly got up and bites the Sinoceratops on the front left leg. Then the fight got too close to the Riders as they quickly got out of the way. And then, the Sinoceratops hooks it's nose horn under the Carnotaurus's right leg and lifts and flips it onto the ground with a thud.

And then, the Sinoceratops begins to make a run for it.

And the Carnotaurus soon got up, and shook it's head. And soon had it's sights on a smaller softer targets.

The Carnotaurus begins to circles them and growls.

Snotlout chuckled nervously. "We're gonna die this time." He then took Hiccup's shield in covered his face.

Then the Carnotaur snarls and charged, but then out of nowhere. A much larger predatory dinosaur caught the Carnotaurus in it's jaws by the neck. And pulls it forcefully to the ground. And then, the dinosaur released it, and shook it's head.

And after getting a good look at it, they realize what it was.

The Legendary Creature.

Until 1902, this 40 foot long, 7 ton monster will known as the most ferocious predator of all time.

The Meanest, and scariest of them all...

Tyrannosaurus Rex.

Hiccup and the others looked and shocked at their savior. And having her left foot on the Carnotaur's neck, the Tyrannosaurus lifts up and unleashes a thunderous roar as the side of the mountain rips open in a massive volcanic eruption explosion.

And then, a sonic blast front wind soared right past them. The strong wind current was enough to interrupt the Tyrannosaurus, and was momentarily stunned. And soon her natural instincts took over, telling her one thing.

Run.

As she took a step, her massive weight crushes and snaps the Carnotaur's neck and killed it. And soon takes off, leaving the immediate area. And soon the Riders followed her lead.

But Hiccup stood there as he watched as the mountain is now cover in a huge pyroclastic flow blanket of ash. And coming his way, and a stampede of dragons and dinosaurs were seen. In the background, there were a pair of Apatosaurus, a Brachiosaurus, and a Quaken. And coming up was a Dramillion, a Stegosaurus, a Triceratops, a Zippleback and an Ankylosaurus

"HICCUP!" Astrid shouted.

And then Hiccup started running as the stampede continues and returned. With dinosaurs, and dragons both running and flying from the eruption. Among the chaos, a Gallimimus narrowly bumps into an Allosaurus. But it snapped it's jaws telling it to stay out of it's way, and an Armorwing bumps into a Boneknapper almost knocking off it's feet. And soon, the Allosaurus was running next to Astrid as she looked and saw the Jurassic predator growling at her. Then suddenly a lava bomb hits the ground near them, and the Allosaurus was knocked off it's feet and rolled several yards before stopping and soon got up again.

"STOP RUNNING SO CLOSE TOO ME, WILL YA!" Tuffnut yelled at Ruffnut

"STOP YELLING AT ME, WILL YA!" Ruffnut Yelled back.

"I'M SORRY! I YELL WHEN I'M TERRIFIED! DO YOU KNOW THAT ALREADY?!"

"I DO KNOW THAT, BUT IT DOESN'T MAKE IT OKAY!"

Then a lava bomb crashed down near Fishlegs. "AHH! HELP! SOMEBODY! ANYBODY!"

"HELP ME ODIN! HELP ME ODIN!" Snotlout cried. "HELP ME ODIN! HELP ME ODIN!"

Then a Nadder was forced to fly lower, and narrowly avoids a lava bomb. And then suddenly, a group of reckless Dragon Flyers came in and started making some last minute catches as the stampede is running towards the distant cliff.

And the cliff drops to 200 feet above the ocean where 2 Dragon Hunter ships were waiting below. Any dragons yet to be capture quickly flew away from the island, and as for the dinosaurs they had nowhere else to go. And some tried to move out of the way as the wall of ash draws closer. And soon, the riders got the edge and looked back as Hiccup is slowly begin caught up with the pryoclastic flow. A Stygimoloch was running next to him, and a Gallimimus ran out of the ash behind him.

"Guys! We have to jump!" Claire yelled.

"You crazy?! I ain't jumping!" Snotlout said.

"It's the cliff or that, Snotlout!" Astrid gestured to the wall of ash.

Then without a second thought, the Riders quickly to the edge.

"Crazy as...!" Snotlout jumped.

Then they all jumped off the edge as the ash reaches the cliff edge. And they screamed before hitting the water. And they all hit the water near a Sinoceratops that was swimming up for air. And as they swam up the surface, a Stegosaurus, Gallimimus, Speed Stinger, Changewing and an Ankylosaurus crashed into the water. And soon they reached the surface.

And they all gasped for air, and the Flyers started rounding up any creatures left in the water.

"We gotta get outta here!" Claire said.

"We just jumped off a cliff." Fishlegs said. "And we're alive. We're alive."

Then suddenly, a hunter net was somehow fired. And then caught Astrid, and the weights of the net then dragged her under.

"Astrid!" Heather yelled.

Without thinking, Heather then dives down and tries to free Astrid. She brought out her ax to cut the ropes, but they were too thick to cut. And the weights got tangled up when Astrid was trying to get free.

Heather then even tried pulling her up, but the weights were dragging her down as well.

Time was running out for both girls.

And if they reach over a depth of 70 meters or 230 feet below. They'll never make it back to the surface in time. And a human can only stay under for no more on average for 2 minutes.

Now Heather is faced of swimming up for air and leaving Astrid to her fate. Or drown beside her.

Then suddenly, someone was swimming towards them. And it was revealed to be Hiccup who managed to escape death. And when he finally caught with them, he quickly brought out his Inferno and sliced the netting. And soon Astrid was free, and the 3 began to swim up.

And they soon gasped for air when they reached the surface.
