Inkvisible Avenues

Inkvisible Avenues is the eleventh mission in Splatoon's singleplayer mode, Octo Valley. It makes heavy use of Invisible Platforms, hence the name.

Octo Valley
The kettle is located on a high platform directly to the left of the entrance to Area 3. Various obstacles including climbing up walls will have to be passed in order to reach it, however.

Mechanics

 * Inkvisible Avenues features many Invisible Platforms, using them for floors, walls, and ramps.
 * Balloon Fish are sometimes used to quickly reveal Invisible Platforms.

Beginning Area
From the starting point, carefully head over to what appears to be a large gap with a Balloon Fish placed directly in the middle. You will then receive a message from Cap'n Cuttlefish informing you that the Octarian forces have hidden the path. Shoot the Balloon Fish to reveal the hidden paths. As soon as you have made it over the invisible path, head over a small ramp and you will notice a relatively small gap with two Octocopters on the other side. Hidden beside the gap are several invisible walls, which you can use to your advantage. As soon as you move in closer to take out the Octocopters, Cap'n Cuttlefish will once again message informing you of an Octoling ambush. Deploy a splat bomb or use your Hero Shot to take out the octocopters and then move on to your next target: the lone Octoling. Once the enemies have been dispatched a Launchpad to Checkpoint One will be revealed.

Checkpoint 1
After you've super jumped from the beginning area, there will be an Octopod. Splat it then move forward. There will be an Octostamp. From there, if you move forward, there will be two Twintacle Octotroopers and a barrier to hide behind. Once you've splatter them, head up the invisible ramp. Turn around and you'll find an Octobomber. Once you've splatter it, head to the next checkpoint.

Checkpoint 2
After you've reached the second checkpoint, there will be some Octoballs. They will roll down on an invisible ramp. Before they roll down, however, there is a crate containing the sunken scroll that gets covered up by the ramp when it is inked. When you get to the top, ink the right side of the ramp to reveal an small invisible platform. Jump down onto it then go under the ramp. Get the sunken scroll inside the crate, then go back to the invisible platform. Ink a path up an invisible wall to get back to the top of the ramp. There will be a checkpoint.

Checkpoint 3
You will super jump to the checkpoint 3. There is a wall and there is only one hole to get to the other side of the wall. Find the hole, swim up and into it, and on the other side, there are 3 Twintacle Octotroopers there. Go and splat them. There are 2 crates with fish eggs in them. Get those, then go up the wall, and super jump to checkpoint 4.

Checkpoint 4
When you get to checkpoint 4, you will see fish eggs. Get them, and that will reveal the hidden path. The path is narrow so moving while a squid is not a good idea. Once you turn the second corner, an Octocopter will appear. Splat it, then proceed. Ink an invisible wall, then you will encounter a Squee-G. Ink another invisible wall, then proceed on the path. The path is a tiny bit more narrow. Once you pass the 3rd turn, another Octocopter will appear. Splat it, and proceed again. Another Squee-G is on a wall. Pass it, then find the path. The path is even more narrow. Once you get half-way across the first strip of the path, an Octobomber will appear. Splat it quickly. The path ends after 2 more turns. There is a launchpad.

Checkpoint 5
Checkpoint 5. Go down, and you will see some walls. Approach the first wall and some Octocopters will appear in the distance. Behind the first wall, is a Twintacle Octodiver. Splat him, then focus on the Octocopters. There are 2 Balloon Fish, to ink a wall, and maybe splat some of the Octocopters. Splat the rest and go up the wall. The final checkpoint will be up the wall.

Final Checkpoint
Break some crates, and you will receive some armor. Go past a wall. A Twintacle Octotrooper will appear on an invisible platform. Splat him, then proceed once. Climb onto the platform, and you will see two Twintacle Octotrooper on 2 separate platforms. Splat them, and proceed again. More invisible ground will appear. Then, 3 Twintacle Octotroopers will appear. Do your best to splat them. Another set of 3 Twintacle Octotroopers will appear, but farther away. Splat them then proceed to the Zapfish.

Sunken Scroll
""Twice a year, the Inkopolis Collection fashion show captures the hearts, minds, and wallets of the city's youth. Is there no room in these creatures' minds for anything but battle and fashion?"

- Sunken Scroll 11

Location: At the second checkpoint, under the invisible ramp. When you hit the second checkpoint, the crate containing the scroll is completely visible, however it is obstructed by a large, invisible ramp. Spray the ramp (and splat the oncoming Octoballs). Stand at the top of the ramp and jump off the side. Angle your momentum toward the underside of the ramp. If done correctly, you should land right next to the crate containing the scroll.

Armor
Location: Breaking the center crate wields armor. The crates on the left and Right hold Power Eggs. Using this Armor, It'll be helpful to get to the Zapfish and get across the group of Octotroopers.

Trivia

 * The Italian name for this stage is a reference to a line in The Little Prince: "It is only with the heart that one can see rightly; What is essential is invisible to the eye".
 * There are no special cans in this mission, and there is only one piece of armor.
