Rocketman kept on pondering down the canal, and they found themselves landing in what appeared to be some sort of waterway.
"What is this place?" Fishlegs asked.
"An underground canal," said Coco as they hit the ground and kept on thundering down it.
Then suddenly, they began riding down a slope.
"Hey, Coco, it feels like we're falling," said Hiccup.
"We're almost to the exit now, full steam ahead until we fly out of here!" Coco laughed.
"This is beginning to feel like a rollercoaster," said Astrid.
"Yeah, it's totally awesome!" Tuffnut cheered with his arms outstretched.
"Hold onto something!" Hiccup yelled.
They began moving even faster down the underground canal, and Astrid wasn't kidding when she said it felt like a rollercoaster. However, within a few seconds, they suddenly found themselves outside.
"All right, there it is!" Teeny yelled as he and the Eret Family saw Rocketman shooting out of the canal. "Time to move out, men! Let be sure to join them and get Eret back!"
They immediately cheered and then launched out of the canal, riding on top of what appeared to be a makeshift boat and pulling it was two large King Bulls; one was right yellow while the other was pink.
"Tidal Wave! Hurricane! Drop!" Teeny ordered.
Hiccup looked out the window and saw them falling directly behind them.
"Dragon!" Teeny yelled. "The entire Eret Family thanks you for helping us! We'll never forget it! Fire the connection cannons!"
They then fired a pair of steel chains at the car's back, causing a stir inside. A few seconds later, all of them hit the water, and the impact did cause them to bounce around a bit.
"Hey, nice job," said Coco. "Pretty high-class Bulls you've got there."
"A little warning would have been nice," said Hiccup rubbing his head.
"No kidding," said Toothless and poked his head outside and looked to the Eret Family angrily. "You idiots, you've got to be more careful!"
"Thanks for the help," said the Eret Family began to cheer.
Coco chuckled. "What a cheerful bunch of guys."
Hiccup then looked at Coco. "Coco, is, is the fastest this Sea Train can go? I was under the impression that this thing was fast."
"Hold your horses; things will change once we hit the railway," she said.
"Railway?" Hiccup frowned and looked out to see. "Where is it? I don't see it anywhere."
"Ah, looks like it just did a bit, huh?" she said and looked at the water closely. "Listen, I know the Sea Trains like the back of my hand; I'll find that railway no problem."
She then looked closely towards the sea, looking for the shadow of the track, which would just be beneath the waves. The only problem was that the storm was making it very difficult to get a precise read, but then she saw it.
"Found ya!" she said and immediately pounced. "Let's go!"
She then immediately grabbed the intercom. "Attention, this train will soon be on the railway! Once we are, acceleration will increase exponentially. Find something to hold onto so that we keep the injuries to a minimum."
"A minimum?" Fishlegs moaned. "We'll be injured regardless?"
The train and shook violently as Coco attempted to get onto the track, but it wasn't easy with these powerful waves slamming into it. One time though, actually shot up into the air along with the track.
"Damn, I missed it," she cursed. "No worries, we're just getting started!"
She then put everything they had into the engines and attempted to get onto the track.
"Listen you, behave yourself!" Coco scolded at the track.
"Whoa, that was close, granny," said Chimney as she and Paws sat on the engine. "A little to the right."
"Don't you worry, I'll get it right next time you'll see," she said, and then her eyes widened when she saw Chimney. "Chimney? Paws? No, I left you with Iceberg!"
Chimney merely laughed, waving.
Coco began to panic. "How could this have happened? Get out from there and get inside; you'll be blown away out there!"
"We're fine, we're fine," Chimney assured her.
However, the train then shook and Chimney and Paw of the boiler.
"Chimney!" Coco screamed.
Fortunately, Chimney was able to grab hold of the railings, and Paws was clinging onto her, but there was no telling how long she could hold on for.
"I didn't fall," said Chimney, strangely cheerful.
"Whatever you do, don't let go!" Coco yelled.
"I'm flying!" Chimney cheered.
"Wait, hold on a second let me slow down," said Coco operating gears, but then she remembered that Rocketman couldn't slow down. "Oh no! I forgot, no brakes! We can't stop!"
Hiccup then poked his head out, wondering what all the commotion was about. "What's going on out there?"
"Look, it's the dragon guy," said Chimney. "Hi!"
"Chimney?" Hiccup stared. "What is she doing here?"
"Hurry, grab those to get them inside!" Coco screamed. "Once this train hits the railway, there will be blown away!"
"On it!" said Hiccup and took on his hybrid form.
He then quickly flew over to Chimney and Paws just as Rocketman hit the tracks. The moment it did elect celebrated at an incredible speed, and Chimney was blown off. Fortunately, Hiccup was able to grab them and was able to keep up with Rocketman and took them inside before anything else happened.
Back on the island, the two conductors had watched the entire thing from a single pair of binoculars, but they were fighting over them.
"Yes, all right! They got onto the railway!"
"What? No way!" said the other conductor and snatches binoculars. "Here, let me take a look. Yes, you're right. I see. I see. Just what you expect from Miss Coco, she something else is energy?"
His colleague then took back the binoculars. "Indeed, I must admit, for a while there, I wasn't sure what was going to happen. I—"
Then once again, his colleague took binoculars. "I know what you mean; with the storm and those waves, it must have been nearly impossible to find a way away."
He then took back the binoculars. "Exactly! Quite right, I can't imagine what it must have been like."
"For sure, for sure," said the other conductor taking back the binoculars. "Just look—"
His colleague then took the binoculars again. "Don't mind if I. Yes, I see."
The two of them and began wrestling over binoculars.
"See something else all right."
"Yes, no doubt. Hey, listen, don't you think we should let Iceberg know what's going on?"
"Absolutely, I bet the old guy has worried himself sick about all this."
"Right, one of us should tell him then," they said in unison.
They wrestle with binoculars for a little while longer before facing one another. Clearly, they both had enough of this tug-of-war.
"Rock…"
"…Paper…"
Iceberg, meanwhile, was still in secret now looking at the water, thinking back to 8 years ago.
It was the day after Tom had been taken away, and they had just received word about Eric. With Tom Workers now know more, Iceberg had to look for work elsewhere, and Coco began drinking heavily.
"So you hear the news?" Coco asked. "They're talking about it all over. Tom's violent apprentice Eric Earlson is now dead. He was hit by a Sea Train. Iceberg, listen… I know you can do it; you were the first apprentice of Tom, the greatest shipwright the world had ever known. If anyone can do it, you can."
"Hey, Coco," said Iceberg looking back at her. "One of these days, let's share a drink. You know when we actually have something to drink too."
"Yeah," she said as Iceberg walked away.
'Tom, I won't let you down. I'll watch over your dreams. I'll protect everything, not only this town, but these blueprints as well,' Iceberg bowed.
He then went on and joined another company, and he began making his way up the ranks until he became the head of the company. He then set out to unite all the shipbuilding companies and eventually became mayor.
Four years later, he was in his office when his new secretary, Kala, entered.
"There's a visitor for you, sir," she informed him. "He says that he's a friend from years back. Do you know anyone named Eric Earlson?"
Iceberg's eyes widened. 'Eric?'
"Shall I show him in, sir?" Kala asked.
"No, turn him away," he said.
Later that night, he met up with Eric in secret in their old warehouse.
"You sure pectoral roundabout way of meeting me," said Eric folding his arms.
"Maybe, but anyway, what's up with that strange new body of yours?" Iceberg asked.
"Screw you, the Sea Train mangled my body, so in order to stay alive, I rebuilt it using some iron scraps. That's not the issue!" He then slammed his hand on the table, looking at him furiously. "I heard that your company is contacted of making ships for the World Government! I won't tolerate you doing anything to help them! How could you? They took Tom away!"
Iceberg himself was furious. "And the weapon to cause the entire incident, have you forgotten who made those? I'm sure you have plenty of things you want to say to me, but I have a few as well. I still haven't forgiven you! Four years isn't nearly enough time for that! I'm surprised you even have the nerve to show your face around here after what happened!"
"What you say?" Eric glared.
"The Government told me that you died in an accident on the railway, you never came back, so I believed it to be true. Even if Tom gave you, remember this it doesn't mean for second that I'm going to."
With that of the way, they immediately went down to business.
"What of all the secrecy?" Eric asked. "Is something going on?"
Iceberg then pulled out the blueprints for Odin and gave them to him.
"Hang on, what are these? The blueprints for that old battleship?" Eric asked that he examined them.
"Don't call yourself Eric Earlson anymore; it only a matter of time before the government targets me. Now listen carefully; I want you to take these and leave this island, Eric."
"Why should I?"
"The Eric Earlson on Tom's Workers is dead; as long as you don't use that name anymore, then there will be no connection between us. Additionally, if you leave the island, the whereabouts of the blueprints will vanish."
"Hey, hold on a second," said Eric. "What if the Government comes after you and you don't have them?"
"I said when I came to say," said Iceberg as he rose to his feet.
"What that? Hey, Iceberg!" said Eric.
"We shouldn't see each other again," he said as he made his way to the door.
"Wait, hold on!" said Eric and Iceberg came to a stop with a huge frown on his face. "Listen to me, do you want to end at the same way as Tom did? Hang onto those blueprints; if your life is in danger, just hand them over, and if you don't want to do that, you can burn them right before your eyes."
"If you were me, would you do that? Tom has achieved so many wonderful things, but he gave up everything to keep these blueprints hidden from the world. As long as the risk remains that a woman named Heather Owson can figure out how to restore the weapon, then the world needs these blueprints to be able to fight back. If I continue to keep them with me, even if they threaten my life, I won't hand them over to the World Government."
"Are you sure?" Eric asked. "You know me, what if I decide to build it? Do you really think you can trust me?"
"I'm giving them to you, doesn't that answer your question? We never change, do we? Every time we meet face-to-face, we yell and argue with each other, I won't forgive you, and you may feel the same way about me too."
Eric's eyes widened when he realised that Iceberg was actually crying.
"Eric, I'm-I'm really… I'm so glad that you're still alive," he said.
"You listen to me!" Eric yelled. "I am not going to leave this island; you got that Ice for Brains? I'm going to do whatever the hell I want to do. You think that I'm going to do what you tell me? I would rather die. Understand?"
Iceberg turned and looked at him furiously. "Dammit, Eric! Why can't you get it through that thick head of yours? This is to protect the blueprints!"
"Shut it, it's you who doesn't get it! I'm not going to leave this island, no matter what!"
Eret had been thinking about that meeting as he climbed onto the top of the car.
"Why the hell my thinking about Ice for Brains at a time like this?" he grumbled.
He still couldn't get over the fact that he was dead.
Hiccup had managed to bring Chimney and Paws inside the car.
"I thought that I was a goner," said Chimney.
"You almost were!" Coco scolded. "I said if he did not come inside, you're going to get blown away!"
"That speed was crazy," said Hiccup as he sat down. "I could barely keep up with the train."
"Told ya," Coco smiled.
As it happened, Teeny, Kalena and Kaley were now inside the car as well, but they weren't the only ones. Palmer had made his way inside as well, along with Lasse and Tilestone.
"No kidding, that was rough," said Tilestone.
"Hurt my back," Lasse moaned.
"Hold on a second; there are a few more people in here than there should be," said Toothless.
"Yeah, who do you mean?" Lasse and Tilestone asked.
"He means you!" Palmer yelled.
"I mean you too!" Toothless snapped.
"I decided to come along with ya," said Palmer. "I tried, but no matter what I said or did, I couldn't stop you. And the enemy you're going through all of this to rescue your friend from is the exact same one that I do kill Iceberg. I've got a word or two of my own that I want to say to those bastards."
"Yeah, you're not the only one!" said Tilestone. "We think it is reasonable the train and followed you we would be right behind you when things went down against those no-good assassins!"
"So here we are, seems our hunch was right," said Lasse. "Let us join you; we want to avenge Iceberg."
"Sounds like we all have a common enemy," said Teeny. "They're the same ones that kidnapped our bro Eret."
"Yeah, he's right," said Kalena. "No point in playing dumb; we know exactly who they are!"
"Hey, Galley Law, if anything happens to him is going to be on your shoulders!" Kaley threatened.
"Can it? Iceberg is the one who endured the most here," said Palmer.
"Hey, what the heck are they talking about?" Tilestone asked, looking at Palmer. "Come on, there's something you're not telling us, Palmer.
"Yeah, it's time to come clean," Lasse agreed. "Tell us everything; we need answers. You know who the true culprit is. We're not stupid, you know, we've got a pretty good idea who it is. You're not going to surprise us."
Palmer sighed. "Well, I guess the story about them disappearing was too convenient. Fine, I'll tell you. The true identities of those masked men are Lael, Silvernose, Kala and Burl from the bar. It was them; they are the ones who try to kill Iceberg."
Lasse and Tilestone looked at him, completely shocked.
"I you telling me you never even thought of them!" Palmer yelled.
"You said they went back to their home towns," said Lasse.
"Come on, you believed that?"
"W-we thought that it was Mud and Dum from the back streets district," said Lasse.
"Right, right," Tilestone nodded.
"Who the hell are they?" Palmer yelled.
"What?" Lasse stared. "You're kidding? You've never heard of them? They're pretty famous in the back streets."
"Right, right," Tilestone nodded.
"Why would half the foreman leave in the middle of a crisis?" said Palmer shaking his head.
"Okay, now that we're all up to speed, let's get down to business," said Hiccup, and everyone looked at him. "Even though we've gotten into a few fights in town with both the Eret Family and Galley Law shipwrights, the enemy were all going after here is one and the same. Now the toughest out of all of them has to be Lael, and I'm the only one who would stand even a chance against him."
"Hiccup's right," said Toothless. "This is a battle to get back at those four goons from the World Government took from us. So we either reach them in time, or all of this will be for nothing."
"Granny, look!" said Chimney as she looked out the window. "It's Aqua Laguna!"
"Oh, it's here already?" said Coco.
"Hey, let me take a look," said Fishlegs as he poked his head outside, his eyes widened. "Oh no!" He then quickly looked back at Coco. "Hey, shouldn't you be in the engine room right now? You've got a find some way to dodge that gigantic wave!"
Coco laughed. "Nah-ah, Rocketman can't be controlled, remember? We can't adjust the speed, use the brakes or change our course. My job ended as soon as I got us up onto the railway. The train is lined up on the tracks, running at full speed, and there's nothing anyone can do to stop it."
"Oh, great," said Fishlegs and looked at Hiccup. "Hey, if we don't do something and fast, this train is going to—"
He stopped when Hiccup held out his arm towards Palmer and Teeny.
"Everybody on this train has the exact same goal; there's no point fighting separately," he said.
"Yeah," Teeny nodded, holding out his arm.
"He's right," said Palmer doing the same.
The three of them then grabbed each other's arms forming the Trinity.
"For this point forward, we fight has one," said Hiccup. "There are two more members of my crew on another train. Once we caught up to them are fighting force will be even stronger. Listen up, we're going to let that big wave beat us; we will achieve our goal! Let's go!"
"Yeah!" everyone cheered as they charge towards the wave.
