Meanwhile, not too far down...

He's alive!

Then, they arrive.
Zan: Don't worry, I've got all of you!
Rho: ...You guys?
Vantas: The robot!
Masterockets: It's the robot!
Geno: The robot!
Zan: Who?
Velshyyr: You can talk?
Rho: Yeah, of course I can...I'm a robot, not a caveman...I just needed this Signal Speaker device!
All: 
So you can't talk!Geno: Oh well, the thing that matters is that he's still among us...But seriously, where are we? I thought this was supposed to lead to an abandoned train station?
Rho: It actually leads to an uncharted robot-inhabited land because it's UNDER the island...It litterally hangs from under the island! This chain here is one of its many supports...They say there's also a secret path somewhere around here that leads to The Underworld.
Geno: The Underworld?
Vantas: You don't know anything, do you?
It's the horribly dangerous world in the shady depths under our comfy floating island world.
Masterockets: It roams with terrible monsters.
Velshyyr: There's also a monster who comes to our world frequently. He's called the Sky Kraken and sometimes, he jumps into the sky to devour another ship.
Zan: The Underworld is the reason I don't like traveling on ships or anything that has to float over the sky...were the ship ever to fall for some reason, I'd die without a doubt.
Geno: Is The Underworld really that fearsome?
Rho: It is. But anyways, this place is in a crCIA. Yesterday, well...that battleship launched. Right after the launch, Dr. Punkzard had already unleashed his right hand man upon us. His name is Coale and he has an almost unbreakable armor. He used a weapon called the Heat Lance to fight. He's a nightmare and he's terrorizing this land! Will you help me stop him? You said you were looking for an abandoned train station...I know where it is, but help me first, please!
Geno: Alright. We'll help you if you get us to the abandoned train station.
Rho: Then it's settled! Now hold on tight to that guy I've never seen before, and to guy I've never seen before, follow me!
