The gang was at Chris's house watching the News.

Scarlet: Naval authorities report that the research vessel Seahawk is missing at sea. Research teams are combing the area for its last known position. So far there are no signs of the vessel.

She showed a picture of the Seahawk.

Scarlet: These pictures were taken two days ago when it left on its mission. Details of that mission are being kept secret, but sources tell SSTV that everything seemed to be going well until early this morning, when the crew radioed to report heavy fog.

Sonic: See, that's why I can't stand water.

Y/n: It was fog, not water, Faker.

Cream: You like water if it's in a glass that's a start, Sonic.

Chris: Maybe the ship hit something after it went into the fog.

Chuck: A ship like that has instruments but let it navigate through fog safely. There may be something else going on here.

Chris: What do you mean, Grandpa?

Chuck: What if the Seahawk's disappearance wasn't an accident? Other vessels have encountered strange phenomena in that area. Perhaps we should take the yacht and have a look.

Cream: Does that mean you're going out on the ocean?

Chuck: Yes, that's possible.

Chris: You're thinking that Emerl's down there somewhere.

Sonic: Hey, Cream. I'm gonna go outside and pick a whole bunch of flowers. Wanna join me?

Cream: Sure, we can give them to my mom, Ella, Uncle Spark and big brother.

Y/n: I'll put mine in the same place I put the other ones.

Cheese: Chao, Chao!

At the white house.

Everyone was listening to a recording of the distress call from the Seahawk, the voice was Topaz.

Topaz: Mayday! May-

And the recording ended.

President: Our rescue team searched the entire area, but haven't found a single sign of the Seahawk or its crew. How could a ship of that size disappear without leaving a trace?

Rouge: Well, what if somebody made the ship disappear? If a thief was planning to steal a ship, he'd make sure not to leave any evidence behind that could clue in the cops. Maybe we have a robbery on our hands.

Advisor: I hope you're wrong, Rouge. That ship is packed with top secret communications equipment that could easily tap into data from all of our military satellites.

President: What's your point?

Advisor: Mr. President, if some maniac were to capture that ship, he'd have access to all the data in our defense network and he could easily bring the entire country to its knees.

Rouge: Hmm, I think I smell a rotten egg.

President: Eggman. I hate to say it, but you may be right, Rouge. This is just the kind of insane plot he come up with.

Back at the Thorndyke residence.

Knuckles was at the door with a man in a red coat.

Ella: Ah, hello, Knuckles.

Knuckles: Very nice to see you, Ella.

Ella looked at the man.

Ella: Eh, have we met before?

Man: No, madam, but I'm delighted to make your acquaintance now.

???: Dr. Cadbury.

Mr. Tanaka was behind them.

Cadbury: Tanaka! You were in my archeology class years ago.

Mr. Tanaka: Your perfect memory has not failed you! That class changed my entire life, Doctor!

He began to sob.

Cadbury: You mean, that's what inspired you to become a butler?

Tanaka: Yes. You taught that household servants played a vital role throughout history.

Tanaka swang his rake in the air like a sword.

Cadbury: You always were unique.

They went to Chuck's lab and were using his computer.

Cadbury: I was at the palace doing some research when those two thugs attacked me and ran away with the map.

Knuckles: It's not a total loss, though. At least we have a digital copy.

Chuck pulled the copy out on his computer screen.

Chuck: Interesting. Why were you studying it?

Cadbury: Are you familiar with the legend of Murasia?

Sonic: Is it a place?

Cadbury: Murasia is a continent that sank into the sea. It was the home of a spectacular civilization that flourished and died long ago.

Y/n: So, like the Thunderhogs and the Echidnas?

Cadbury: Yes. According to the legends, the Murasians possessed a highly advanced culture and accomplished spectacular feats of engineering. However, in spite of all its amazing achievements, the magnificent Murasian civilization was wiped out in an instant.

Knuckles: If the legends are even partly true, then the ruins of that civilization could hold priceless secrets!

Chuck: First, the Seahawk is lost, and then this map is stolen. I have a feeling there's some kind of connection, but I'm not sure what it could be.

Cadbury: The Seahawk was searching for Murasia. It was using this map as a guide. You see, the map reveals the continents of our world as they were in the distant past. Here. I'll show you. Now, when we adjust the data, it reveals how our world appeared prior to the volcanic eruption that destroyed Murasia.

A small red dot appeared on the map.

Cadbury: You see there? One piece is missing, just like in a jigsaw puzzle. It's the final clue we need to find the lost continent.

Tanaka: I see it now. That is where Murasia was located!

Cadbury: Exactly! Further analysis reveals that a piece of the continent survived the disaster. A tiny Island which exists to this day. And that's exactly where the Seahawk disappeared.

Later.

The gang except Cream, Cheese, Vanilla and Spark were on the Thorndyke yacht with the previously stated seeing them off.

Cream: Bye-bye, now.

Cheese: Chao chao!

Vanilla: Have a safe voyage!

Spark: We look forward to your return!

Tails: Later.

Chris: Bye, guys.

Amy: We'll take lots of pictures for ya!

Ella: Bye, sweetie!

They sat off.

Cream: Bye, and be careful!

Cream pulled out a piece of paper with the picture of a Chao's face on it.

Vanilla: What's that, Cream?

Cream: I don't know. Y/n gave it to me and told me to lay it down and slap the center with my palm.

Spark: (smiles) Oh, I get it.

Cream: What?

Spark: Just do what your brother told you and find out.

Cream: Okay.

Cream laid the paper down and smacked the picture, when she did the Chao Tea appeared in a puff of smoke.

Tea: Huh? Hello.

Vanilla: A talking Chao?

Cream: Aren't you one of those Chao that big brother summoned to help fight Chaos?

Tea: Yes. I am Lord Tea. And you must be the Cream girl I heard so much about.

He looked at Vanilla and Spark.

Tea: Ah, it seems we have company. Oh, Spark boy. Great to see your back.

Spark: Sorry that I wasn't there before, Lord Tea.

Tea: And who might this young lady be?

Vanilla: I'm Vanilla. Cream's mother.

Cream: Why are you here, Lord Tea.

Tea: Well, your brother, Y/n boy, said that since you mastered Spindash you should take your training to the next step.

Cream: In what way?

Tea: We're going to the Chao Shrine. I'll explain when we get there.

Vanilla: Is it okay if I go?

Spark: I'll go, too. I think I can help with this training.

Tea: Sure. But to you, Vanilla girl. You can only go with you agree to help ma in the kitchen.

Vanilla: Ma?

Cream: That's what he calls his wife, Lady...

Tea: Biscuit.

Cream: Right.

Vanilla: Okay, deal.

Tea: Then grab on to me.

All four of them touch Tea.

Tea: And of we go!

They disappeared in a puff of smoke.

With the yacht.

The sun was starting to set as Chuck, Cadbury, Sonic, Y/n, Knuckles, Chris and the captain were looking at the map.

Chuck: Getting there won't be easy.

Cadbury: That island is really just the top of a huge volcano. There's a whole chain of volcanoes underwater here making this one of the most unstable regions in the whole world.

Sonic: This whole story seems wacky to me.

Knuckles: The doctor knows what he's talking about. You're just getting nervous because you're surrounded by H2O.

Sonic: Water doesn't scare me anymore! I just don't like getting wet.

Y/n bonked them both on the head.

Y/n: Quit your bickering or I'll throw you both over board and zap you right after.

Knuckles/Sonic: Yes, sir.

The next day.

They were finally reaching the island.

Amy: Well, there it is, guys.

Sonic: Let's go ashore now so we can get off this tub.

Knuckles: You're not in charge here, Sonic.

They all gasped as they saw something coming out of the ocean.

Cadbury: Look there!

The thing made a splash so big that it knocked the X-Tornado over and knocked off one of its legs.

Tails: Ahh! The X-Tornado!

What came out of the water was a mechanical viking ship with Eggman's logo on it.

Amy: That ship belongs to Eggman.

Y/n: Gee, how did you figure that out? Was it the logo or the fact it's made of metal?

Bokkun flew down with a TV.

Bokkun: Captain Eggman has an important maritime message for ya!

The message came on.

Eggman: Surrender to me now. My new Egg Battleship has enough firepower to take on the navy, the air force and the hedgehogs too!

Sonic: You stole that map from Dr. Cadbury!

Eggman: You think so? Now why would I do a thing like that?

Amy: Just because you're so despicable.

Y/n: To get a piece of the Murasians technology or maybe have access to the underwater volcanoes?

Eggman: That map led me here to the world's hotspot.

Chuck: I don't follow you.

Cadbury: I do. A hotspot is supposedly the weakest part of the planet's crust. If a volcano inside the hot spot erupts, all the other volcanoes in the world erupts too. But no respectable geologist believes such a bizarre Theory.

Eggman: Well, excuse me, Dr. "I Know Everything," but whether you realize it or not, you're floating above a hotspot right now!

Cadbury: Now I see what you're getting at. The Legends are vague... but it's possible that the Murasians somehow caused the deadly volcanic eruptions.

Chuck: Didn't any Murasians survive?

Cadbury: It's likely that the Murasians were all wiped out. There's no trace of them in the archaeological record after the volcano erupted.

Eggman: I don't have time to listen to you academic airheads discuss a bunch of scholarly mumbo-jumbo, thank you. The Murasians cracked open that hotspot once and sank a continent! Now I'm going to blast it open and cause a worldwide catastrophe! And on the ruins that remain, I'll build the Eggman Empire!

The video ended.

Sonic: Oh, yeah?

Sonic jumped up and used Spindash on the Battleship, but Eggman put up a shield and blocked it, sending Sonic into the water.

Chris: Sonic!

Chris jumped in after him.

Tanaka: Mr. Chris!

Y/n: Dammit, kid!

Y/n jumped in as well while Chris had already got Sonic.

Tanaka: Don't worry! I'll save you!

Tanaka threw a lifesaver at them and it hit Chris in the head.

Sonic: Thanks, Tanaka!

Eggman started firing missiles and lasers in the water.

Y/n: I'm gonna kick both of yours and Tanaka's asses if we get out of this alive.

Y/n used on of his Chaos whips to grab Sonic and Chris then the other to get back on the ship.

Y/n: Glad we got out of that.

Tails and Chuck were fixing the X-Tornado.

Amy: We're in danger. Can you fix this thing faster?

Tails: I'm trying, Amy, we need a little more time!

Y/n ran to them.

Y/n: Let me lend a hand.

He began to help them with the X-Tornado when the captain spoke from Chuck's walkie-talkie.

Captain: Sir, we've spotted something on the sonar.

Chuck: Can't this wait? I'm a little busy right now!

Captain: But, sir, there's another ship coming this way. It's surfacing now!

Cadbury: Who could that be?

What looked like a rocket came from the ocean and shot the Battleship's lasers.

Inside the rocket.

There were three pilots and Rouge was standing next to the main one.

Pilot: We caught him by surprise. Dr. Eggman has his defenses down! Now we can blast him out of the water.

Tails: All right!

Chuck: It's a government ship.

Main Pilot: (Over intercom: Surrender now, Eggman, or we'll destroy your ship.)

The main pilot spoke to the other two.

Main Pilot: Prepare to fire on my order.

Both: Aye aye!

Rouge: I want in on the action too!

Main Pilot: You're only aboard this ship as an observer, Rouge. Lock on target!

Eggman: (Over intercom: If you want to play chicken I'll be happy to clip your wings!)

The Egg Battleship took to the air with the rocket and showed more lasers which he fired at the rocket.

Main Pilot: Let's get him, guys, Fire!

They fired back.

On the yacht.

Chris got a towel wrapped around him.

Tanaka: (crying) I am happy to see you!

Sonic: Don't cry. We've got enough water.

The fight between the Battleship and the rocket was still going on and the rocket ran through the lasers, breaking them off.

Pilot 2: Dr. Eggman should've surrendered when he had the chance.

Tails finally got the X-Tornado working again and was leaving with Chris, Sonic, Knuckles, Y/n and Chaos.

Tails: Everything's set for takeoff.

He took to the sky.

Tails: Transform X-Tornado!

The X-Tornado fully transformed to its jet-mode. Then, a hologramic projection of Topaz, the Commander and a bunch of sailors showed up in front of the Egg Battleship.

Rouge: It's Topaz! She's still alive.

Eggman: (Over intercom: Stay away! If you destroy my ship your comrades will go down with me!)

Eggman let out his usual laugh.

Knuckles: Eggman, let them go!

Eggman: (Over intercom: Fat chance! I'm holding them hostage just to make sure I get what I came for.)

The rocket hit the Battleship and Rouge grabbed the Main Pilot.

Rouge: Wait!

Main Pilot: Back away! Hostages or not, my job's to stop Eggman. If you try to stop us, we'll treat you like an enemy.

Another pilot held a gun to Rouge's head which made her let go.

Main Pilot: Either way, we're doing our job!

The rocket continued shooting the Battleship.

Chris: Those hostages need our help.

Tails: No sweat, Chris. Ready for action, Sonic?

Sonic: Watch me!

Tails: What about you, Y/n?

Y/n: Me and Chaos can handle anything. You up to it, partner?

Chaos: You know it.

The X-Tornado started shooting the rocket while Y/n swang a Chaos Whip around to block all the rocket's attacks.

Pilot 2: Hey, whose side are they on?

Rouge used the distraction to take the gun and break it in half.

Rouge: All I need is 10 minutes tops.

Main Pilot: Okay. But when your time runs out, I start shooting.

Rouge nodded and flew out of the rocket as the Battleship tried to fly away.

Knuckles: Not her again!

Y/n: Rouge is our Ally, Knuckles.

Knuckles: I know, but she's just so annoying at times.

Sonic: She's heading for Eggman's ship. We have to distract him somehow!

Knuckles: Go for it, Tails!

Tails started to shoot the Battleship and Rouge used the time to get in. Then, a giant gun that looks like a satellite came from the Battleship and aimed at the X-Tornado, yacht and rocket.

Sonic: What's that?

Y/n: Nothing good. That ray gun seems like it covers a wide range.

The ray gun began to charge up energy.

Cadbury: There's nothing we can do!

Sonic and Knuckles jumped at the ray gun to try and stop the blast but failed.

Decoe: (Over intercom: Surrender now, or we will fire the energy ray in ten seconds.)

Knuckles: We don't have any time!

Sonic: We can't give up! Maybe if we attack it together!

Y/n: With Sonic's speed and your strength, Knuckles. It'll surely work.

Knuckles: It's worth a try.

Y/n: Me and Chaos will assist you.

All three of them jumped at the energy ray. Sonic and Knuckles joined hands and started to spin like a wheel while Chaos bladed arms incised both of Y/n's and they spun Screw Kick style.

Y/n/Chaos: Chaos Spin!

Both attacks hit the energy ray and destroyed it. The four landed safely on the X-Tornado.

Sonic/Knuckles/Y/n/Chaos: All right!

The Battleship started to go down.

Eggman/Decoe/Bocoe: What do we do?

They realized something.

Eggman/Decoe/Bocoe: We still have our hostages!

The hostages and Rouge came to them with guns.

Topaz: Not anymore.

Rouge: Face it, Doc, there's no way out this time.

The three started to panic.

Eggman: Hey! Where'd my Chaos Emerald go?!

Rouge looked around for it, and when she turned to see Eggman and his robots, they were gone. Escaped in the Egg-Mobile onto the island.

Topaz: Oh, Rouge.

Rouge: Sorry.

The Battleship sank, but everyone got out safe.

Cadbury: Maybe this trip was a big mistake. Maybe we never should've come.

Chuck: If Eggman finds the ruins of Murasia, it could be dangerous.

Cadbury: Yes. I'm beginning to think that Dr. Eggman was right and that this place really is a hotspot.

To be continued.
