Platform Madhouse

Platform Madhouse is the twenty-fifth mission of Splatoon 2's single player mode Octo Canyon.

Octo Canyon
Take a yellow saucer and transfer to a green one. Drop off at the platform with a Ink Switch and a checkpoint. Do not hit it yet as it will cause the walls on the sides to close in, obstructing the path. Get onto the thin moving platform on the other side, then hit the Ink Switch. This will bring you an inkable wall to get on top. Get on to the wall closer to the Ink Switch as it returns to its original position, and the kettle is on a platform nearby.

Beginning
Drop down to the large platform below. Cross the two sets of moving platforms and splat the Octodivers and Octotroopers, then break the crates ahead and pick up the key. Doing so will trigger the first checkpoint and spawn in more Octarians.

Checkpoint 1
Turn back towards the large platform you just dropped on. There will now be two Twintacle Octotroopers in front of the moving platforms and two Octocommanders behind them. Splat them and take the key to the vault on the large platform, revealing a launchpad to the next checkpoint.

Checkpoint 2
Drop off and break the crates for a canned Ink Storm. The player will now have to platform to the other side on moving platforms moving against them, with large gaps needed to be made. There will also be Octotroopers on uninkable blocks shooting the player, and taking them out before crossing a gap is advised. At the corner where the moving platforms change direction, a small stable platform with the next checkpoint floats above them.

Checkpoint 3
The player has to platform just like the previous checkpoint, but now with additional barriers, Octocopters and Octobombers interfering with their jumps, and two stable platforms with Octotroopers sitting on uninkable blocks nearby (the right one shielded), and a splat-switch on the wall nearby. The player has to get to the other side and activate both splat switches to move the walls aside to reveal a team of Octotroopers with an Octocommander in the middle. After splatting them all, a launchpad appears, taking the player to the next checkpoint.

Checkpoint 4
Below is a set of moving platforms moving in a similar fashion to conveyor belts, towards the right. There are two Octocopters, a row of uninkable blocks and a block on the other side to the left. Make your way to the block and board the next conveyor belt-like set of platforms moving to the right. There are Ink Pistons to restrict the path so move around them. There will be a Deluxe Twintacle Octotrooper on the other side. Defeat it with the help of the balloon fish nearby and get to the next checkpoint.

Checkpoint 5
At this point the path takes a left turn, so now the player is moving against the conveyor belt. There are two Octocommanders on uninkable blocks on the side, 2 barriers to hide from them, and two balloon fish in the middle of the conveyor to help turf. Make your way to the other side and climb up the next conveyor moving upwards. Drop down and land on the next checkpoint.

Checkpoint 6
There are Ink Switches littered throughout this section. Hit any of them to power a moving block and ride it. Several rows of uninkable blocks will be placed to help you reach the Ink Switches and board the block. The player will come across several obstacles along the way, first 2 Octocopters spawn to interfere with the progress, then there is a grate that can sweep the player off. After that, the block gains height and reaches the final checkpoint.

Final Checkpoint
The block then continues to move around an Ink Switch with an Octobomber nearby. Barriers provide footing for the player to hit the Ink Switch but may also push the player off. When the block takes its next turn, it starts rotating horizontally anticlockwise, and on the next it starts rotating vertically. The player must get to the top before it flips or they will fall into the abyss. A stable platform at the same level as the top of the block when it is done rotating has the Zapfish sitting on it.

Location: The platform with the Zapfish on it will have a splat-switch on the side. Inking it will reveal a launchpad to what Sheldon calls a "Deserted Island". Get away from the Octostamp DX to get the scroll, and the launchpad will take you back to the Zapfish.

Sardinium
Location: After Checkpoint 5, climb over the giant moving wall. Look to your left and look down. There will be a small grassy platform with the Sardinium.

Platform Madhouse has 3 pieces of armor to collect.
