Mission Briefing
Reach the end and rescue the Zapfish using Splat Switches to open up a path for you to take, but be careful: There are a lot of surprises around each corner...

Mechanics
Splat switch

Beginning
Once you start, there is an Octotrooper on the right side of the block. Take it out, then splat the Splat Switch on the block. This makes the block rise and rotate, revealing another block underneath it. As they rise, ink a passage up them and jump onto the next platform. Once you are there, splat the Splat Switch in front of you. It will flip, revealing an Octotrooper on the back of it. Take it out, then jump across the gap to arrive at the first checkpoint.

Checkpoint 1
Now you will see two canned specials: Inkzooka to the left, Bubbler to the right. Choose one because you will need it. Take the Launchpad to the next platform. You will see three Octoballs, take them out but be ready for a surprise...

Once you splat the Octoballs, four platforms will appear, each with a Twintacle Octotrooper on it. If you grabbed the Inkzooka, you could use it to splat all four quickly, or if you chose the Bubbler you could use it to protect yourself as you take out the Octotroopers. As you do so, the platforms will alternately rise and fall. Once you splat all four Octotroopers, a Launchpad will appear, thus taking you to the next checkpoint.

Checkpoint 2
Once you land, there will be an Octotrooper in front of you. Take it out and jump onto the next platform. There you will see two large blocks, and the right one has a Splat Switch in front. Splat it, and they will rotate. As they do so, two more Octotroopers will become visible. Take them out and ink the sides of the blocks so you can reach the top. You will see five blocks arranged in a cross shape. The bottom one will have a Launchpad, and the middle one will have a Splat Switch. Ink the switch, and the blocks on the side will move downward. Two new blocks (previously out of sight) will take their place, and each of those blocks has an Octotrooper. Take them out, and ink the sides of the blocks. If you go to the top without taking the Launchpad, you will see an orange crate behind the top block, on a platform which you cannot see from the front. Break it open to reveal the Sunken Sea Scroll. Collect it, and go back to the side with the Launchpad. Swim back up to the Launchpad, and fly over to the next checkpoint!

Collectibles
1x inkzooka, 2x bubbler

Sunken Scroll
"From the depths of the sea we emerged long ago, seeking the light of the surface. In search of still greater lights, we now send this message into outer space, sealed in a disk. Perhaps one day, we will encounter other intelligent life..."

- Sunken Scroll green

Location: At the second checkpoint, behind the Splat Switch contraption. After hitting the second checkpoint, go through it normally until the launchpad on the wall later is available after activating the splat switch. Rather than climbing the wall and jumping into the launchpad, go around it on one of the side platforms and jump to the platform behind the wall where the scroll is located.
