Boxes Locked! Keys, Please!

Boxes Locked! Keys, Please! is the 3rd level in Splatoon 3's story mode, Return of the Mammalians.


The location of the third Kettle in The Crater.

Accessing the third level is unsurprisingly another straightforward process, as the player has to continue walking down the corridors yet again until their path is blocked by more Fuzzy Ooze. On their left, they will see the kettle.



The first vault hiding an inkrail.

The level starts off with the player being confronted with a bunch of Crates. Among them is a vault to which the responding key is just ahead, hidden inside a crate. After unlocking the vault, the player can use an Inkrail to progress to the next checkpoint.


The main section with three different paths.

The final section begins with the player given the choice between 3 paths. For the path in the middle, the player has to activate a Splat-Switch, but then will see that to progress further they need to get past two more vaults. On the left there is another inkrail, leading to a small portion where two Octocopters will try to shoot at the player. A vault will be surrounded by grates. When the player finds the key, they can unlock the vault revealing yet another inkrail. While that inkrail will lead back to where the section started, it will be essential to progress further soon enough.

The player getting attacked.

Afterwards, the player should progress to the right path, where the player has to throw Smallfry towards another inkrail in order to activate it. Then they will be required to activate once more an inkrail leading up a small tower, on top there is a crate holding a key and yet again an inkrail, however this time the player will realize that they cannot reach it from there, they can merely activate it. After returning back to the main section, they will see that they can use the inkrail to jump on top of the other and reach a new area, hiding the last key required. After unlocking the two vaults, they will have to activate the last inkrail of the level and ride towards the Zapfish, finishing the level.

The player jumping from one inkrail to the other.

During the mission:
How 'bout that. Nice moves you got there!
Thar she glows! I can see the Zapfish from here.
Remember-you can slip under or through grates by pressin' to get into swim form.
Aha! You activated an inkrail! Hop on and ride it by pressing .
If your ink won't reach, it's Smallfry's time to shine!
You wanna get to what's inside that vault? You gotta find a key!
Think you could jump from one inkrail to another? It's worth a shot!
Now, don't panic, but if you let go of , you'll fall to your doom. So hold on tight!
Try as you might, I don't think you're gonna be able to hop onto the inkrail from here...
Octocopter spotted! Ink it up!
Well, well, well. Another vault. Find the key!
There it is! Grab that key and unlock the vault.
There you go. Now ink up that thingamabob!
After the mission:
Keep it up, Agent 3! You're making me proud.
Now, I don't wanna ruffle your tentacles any further than they've already been aruffled, but...
Those fuzzy Octarians are freakin' me out.I think we oughta consider callin' some backup.
Lemme just fire up the ol' communicator... Check, check! This is Cuttlefish, over. Do you copy?

Agent 1
Well, what are we waiting for, Agent 2? Let's go collect him!
Agent 2

...Did they just hang up on me?!
Agents these days, am I right? So impatient...
Ksss-ksssh! Kssssssht!
GYA...A HA... Cuttl... I foun... you!
Dagnabbit, this ol' thing is busted. Oh well.
C'mon, let's go!
