Deepsea Metro

The Deepsea Metro is a subway system running under the sea near Inkopolis that serves as the mission hub for the Octo Expansion.

Layout
The Deepsea Metro is operated by the Kamabo Corporation, and its many conductors are C.Q. Cumber. Iso Padre, Cap'n Cuttlefish, and the denizens of the deep are seen riding in subway cars as passengers, with specific denizens varying based on which line the car is on. The metro is used to transport test subjects to tests, commute employees of Kamabo Co. and as a regular subway by the denizens of the deep.

The Deepsea Metro runs along ten lines, denoted by the letters A to J, each containing stations that serve as the expansion's levels. There are a total of 85 stations, including eighty mission stations, four thang stations, and Central Station. 22 of the mission stations are exchange stations, connecting two different lines of the Metro. When Agent 8 completes an exchange station's mission for the first time, the connecting line is revealed and C.Q. Cumber gives them CQ Points as a reward.

The Low Water Party
Sometime after the events of the Octo Expansion, the metro was that year's host to a rave called the Low Water Party. Despite the fact that knowledge of the event only had spread orally, the rave recieved 60 billion participants from Inkopolis, causing the sea level above to rise by 30 centimeters. The event was begun with Dedf1sh's music playing, although she did not show up. After it stopped playing, major artists such as DJ Octavio feat. Callie and Bob Dub appeared one after another, as well as an impromptu appearance of Underpass Bass Drum, a Rainmaker team consisting of Kuze of Hightide Era, Bertie Feeder of Bottom Feeders and Ryu Chang of SashiMori. When one of them said that it was their first time with the double bass, the audience got "hyped up."

Off the Hook, Cap'n Cuttlefish as MC Craig and Agent 3 as SANGO® participated too, with Marina and Agent 3 having an 8-hour long "DJ battle" and Pearl and Cuttlefish holding a rap battle filled with language that was described as being too vulgar for mainstream publication. The four's participation caused several ravers to forget about returning to the surface and go missing, and it is said that some have yet to return.

"EXCUSE ME?"

"Hwa-?! Who am I speaking to? Where is Agent 3?! State your names!"

"Oho?! Check it, kid. Are you stepping to me with a rap battle? MC Craig in the house! Call me Cap'n Cuttlefish, but not because I cuddle with fish. Smooth like butta bet you wish that you could stunt a flow like this!"

"Mount Nantai... Why that's near Octo Valley! Agent 8 and I were near there, but orange seems to have taken us deep underground..."

"OK, well... Anyone who loves rapping is a friend of mine. Thanks for your help! We're off to pass some sorta tests and make our way to the orange! And by "we," I mean you, Agent 8! Time to get after it!"

"Not sure this Iso Padre is playing with a full deck... Doesn't seem like a bad chap, though."
 * After Iso Padre comes aboard:

"Yo, Agent 8 — what's up?"
 * General:

"Dear Inkopolis, you're in my heart forever! Squids and Octos sharing turf together!"

"Yo Inkopolis Square represent one time! Check yourself before ya step to my rhymes!"

"Always lookin' proper, dapper show-stoppa. Who's that you say? I'm talkin' Iso Padre!"

"Are you tight with my boy Iso Padre yet? That dude has got some swag for days!"

"Hearin' 'bout yo memories makes his day! Who I talkin' 'bout? You know it's Iso Padre!"

"Glasses, a chain, and he loves mem cakes. Who I talkin' 'bout? Iso Padre — no mistake!"

"Shout out to my Deepsea Metro crew!"

"But the vibe in here is all quiet and hushed! Hopes and dreams tangled in a mystic mush!"

"The riders in here be all shapes and sizes! Talkin' to me like winning mad prizes!"

"C-C-C-Calamari County is where I'm from! Keep it superfresh 'n' we can def be chums!"

"I reckon you can find jellyfish no matter where you go in this world... Mad respect."

"I'm just chillin' in the train, sittin' and swayin' to the click-clack beats..."

"All for one and one for all... That's a rock-solid rule for good teamwork!"

"MC Craig in the place to be, y'all!"

"What's up, what's up?"

"You've been working too hard, Agent 8! Why not chill for a bit?"

"Gaggle o' dudes—mouths snippa-snappin'. I ain't home yet, so I stay busy rappin'."

"It's hard keeping up with the youths these days, ya know?"

"Job well done, but h-h-h-hold the phone, no time to rest 'til you get back home!"

"Did you hear about my new hobby? That's right. I'm a rapper now."

"Check ch-check check check ch-check it out!"

"It's a new world for a retro type of squid! But who's gonna save it now — is it you, kid?"
 * Before defeating Commander Tartar:

"It's dark down here in the Octo-underground - Sometimes I cry when there's no one around!"

"Crushin' each test and bringin' the pain! Got Squid Sisters tunes all up in my brain!"

"Collect the four thangs and we'll be OK! Find the four thangs for a new day!"

"When this journey's done, I'ma take a bath! Get in my way and you'll feel my wrath!"

"He's a sleepy sea slug, don't you forget it! Giving out advice so ya don't look pathetic!"

"Remembering days past with mem cakes. Groovin' to this subway melody so awake!"

"That cash you borrowed? Gotta pay it back! You're the chosen one — get ya own stacks!"

"Heck da dip 'n' dives of my d-d-dope beats! Call me an old squid and I'll bring the heat!"

"Hoo hah, one two, always fighting back. Mess with my nap? You might get smacked!"

"You know we're headed to the promised land! I'll get you there, baby — just take my hand!"

"It's been a while, Agent 8! Glad to see you're still alive and kickin'! I got curious how things were down here... And you know, this place has grown on me! Where's who? Oh, Agent 3 had business to finish up and headed out back on patrol! If there's anything you've got left to do down here, I'll be glad to offer my support!"
 * After defeating Commander Tartar:

"Kamabo Co.'s CEO got legit smacked down! Finish up your biz and let's head to town!"

"Commander Tartar? His days are done! You took him down like the setting sun!"

"Kamabo Co. tried to mash us into paste! But Agent 3 showed up 'n' laid 'em to waste!"

"Phew..."
 * After talking to much:

"I'm pooped..."

"This rapping business is quite exhausting."

"Might be a good idea for you to rest up too."

"Peace out — I'm gonna catch a few Zs..."

"The jellyfish down here got super long necks. I'm an old squid who loves cashing checks."

"Beg your pardon, young squire. Might I orange at those trinkets you've got there? Forgive me if I caught you off guard. grey They call me orange. That's not my name, mind you, but it's the only one I recall now. Down here, we call those thin slices of memory orange. I've spent an age or two in the depths, hungry for them.

Trivia

 * With exchange stations having two numbers, one for each of the lines they connect to, the first number is always backwards alphabetically. For example, Girl Power Station is denoted (and not ) because J comes after D in the alphabet.
 * The mem cake for these stations is always from the series of the latter letter line as well.
 * The music played in the subway train has a few notes of the Calamari Inkantation played in the background.
 * More notes are added as Agent 8 gains access to more lines. After clearing the game, the complete track containing the main melody of the Calamari Inkantation is played.
 * According to sound director Minegishi in a Famitsu interview, the Calamari Inkantation can be constructed as Agent 8's auditory hallucination, an inner melody of their mind that intensifies as more of their memory returns.
 * A poster advertisement of a video game console, resembling a Nintendo Entertainment System, can be seen in the subway train.
 * The name Deepsea Metro can be construed as a homonym of the D.C. Metro.
 * The Deepsea Metro can be seen in a map that appeared in a developer interview.
 * One of the inspirations during development were the New York subway system.
 * All of the 8-ball levels have a subtitle of a Magic 8-Ball result.
