Splatoon 2/Octoseeker Shakedown

The Kettle for this mission can be found on an octagon-shaped platform to the left of Beaker's Depot. To get to it, ride the ride rail down to the lower level of the area. Near the ride rail that leads to the higher area, ride two moving blocks to a blocked off area filled with three sprinklers. A ramp on the area leads to a platform. Take a right onto the platform with the kettle.

Beginning Area
To the front immediately is a launchpad. Use it, and ink the sponge ahead. Climb up it and defeat the Octotrooper on top. Break through the crates to use the ride rail to a platform with a patrolling Octoseeker. It is easy to get through with quick movements. Ink the wall ahead and take the launchpad to the next checkpoint.

Checkpoint 1
Ink the sponges ahead and climb up on them. At this point an Octoseeker starts patrolling the area. Quickly take a left turn, ink and hop across the sponges, splat the Shielded Octotrooper and break the crates to get to cover. A key is hidden inside a crate in there. The game intends the players to splat the other Shielded Octotrooper, take another right turn and go around the structure, but they can just go back to the direction they came from and get to the vault with the launchpad and head to the next checkpoint.

Checkpoint 2
Ink and cross the sponges ahead, take a right turn and splat the Octotrooper ahead. Pop the balloon fish behind the Octotrooper to ink the sponges, go over them, take a right turn and splat the Octotrooper there. Get onto the platform ahead, pop the balloon fish, and go over the sponges. Splat the Shielded Octotrooper, get to the launchpad and head to the next checkpoint.

Checkpoint 3
Ink the sponge ahead and climb up it to reach a circular platform with a giant pole in the middle and an Octoseeker patrolling above. Take on either the left or right Octotrooper and get to the sponges on the other side. Drop off to the next platform with another Octoseeker patrolling. Splat the Octotrooper to the left, and ink the sponge in the middle. Climb up the structure in the middle with the sponge, get on the Octoseeker and get to the next checkpoint.

Checkpoint 4
Climb up the wall and splat the Octotrooper and Shielded Octotrooper ahead. Ink the sponges to climb up to a circular uninkable platform with a giant pole in the middle, and an Octoseeker patrolling above. The game intends you to move anticlockwise along with the Octoseeker, but it is faster to go clockwise and break the crates to get to the launchpad to the final checkpoint.

Final Checkpoint
Pop the balloon fishes on the sides to ink the sponges. An Octoseeker will pursuit and destroy the player's footing. Move quickly to the other side and hop into the launchpad to get to the Zapfish.
