Spongy Observatory is the twenty-third mission available in singleplayer Octo Valley. The mission is named as such because of its heavy use of sponges.
Starting in the entry of Area 5, Head to the right, use the entryway, but it's blocked off by a grate, in which Agent 3 can simply clip through it in Squid form. There is a Propeller-Lift. Use it and get up the wall it stops at. Now get up the grate slope. there is an Inkrail but don't take it. There is a wall behind the Inkrail. Using the wall, there are 2 dry sponges. Use the sponges, and get up the small wall.
Starting mission 23, there is a balloon fish, which can wet the 4 sponges, getting Agent 3 to another Checkpoint.
Checkpoint 1
There are 2 Octostamps to fight off. They're standing in sponges, so if they do attack, they'll shrink the sponge. Splat both of the Octostamps to reveal a Launchpad.
Checkpoint 2
An Octotrooper guards a platform which to get across, Agent 3 has to go through 2 sponges. If the Octotrooper starts shooting, the sponge will shrink. Be careful of staying up on the sponges to get across. Throw a Splat Bomb to the Octotrooper and it'll stop bothering Agent 3 from getting across.
Checkpoint 3
After wetting the 2 sponges to get to the next platform, Agent 3's is going to have to get across a sponge alley, guarded by 5 Octotroopers. There is an Inkzooka to help get across easier. Not using the Inkzooka can be challenging, due to enemy ink Shrinking a wet sponge. If chosen to not use the Inkzooka, take out the Octotroopers to make it easier, but be cautious they can shoot it at a high fire rate, making a wet sponge shrink faster.
Checkpoint 4
Another Balloon Fish can be used. There are also 3 crates on the right, one crate holds armor. Still going, another Balloon Fish can be found, and also an Octobomber. Take out the Octobomber, so that it won't shrink the sponges.
Checkpoint 5
Yet another Balloon Fish can be found wetting 4 sponges, it can also be used to take out the 2 Octobombers. Wet 2 more sponges to go to the next checkpoint.
Checkpoint 6
Using another Balloon Fish, Agent 3 has to make their way up on the mission but will meet about 2 Octobombers. One is just flying around but will chuck a Splat Bomb if found, and one guarding an area, which can shrink a sponge if caught, toss a Splat Bomb at the sponge. Once Agent 3 passes them, the mission continues.
Checkpoint 7
Wet the sponge and get on it. Start putting ink on the wall to swim down and reach the Launchpad. It is also possible without putting ink on the wall, just perform a swimming squid jump off the sponge, and face toward the wall while still in Squid Form, Agent 3 will automatically activate the Launchpad, going into the final checkpoint.
Final Checkpoint
A small crate holds an Inkzooka, going into the area will trigger an Octoling fight. Using the Inkzooka, Agent 3 can Insta-splat the 2 Octolings. Once both of the Octolings are defeated, a Launchpad will appear. Take it to get the Zapfish.
