Mechanics
This Mission holds about 50 Sponges.

Beginning
Starting off 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 Octotrooperand it'll stop bothering Agent 3 from getting across.

Checkpoint 3
After Wetting the 2 Sponger to get to the next platform, Agent 3's is going to have to get across a Sponge ally, 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 Ink Balloon can be used. There are also 3 crates on the right, one crate holds armor. Still going, another Ink balloon can be found, and also an Octobomber. Take out the Octobomber, so that the it won't shrink the Sponges.

Checkpoint 5
Yet another Ink Balloon 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 Ink Balloon, Agent 3 has to make his 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 an Splat Bomb at a the sponge. Once Agent 3 passes them, the mission continues on.

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 preform 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 reveal, and the Zapfish is all to Agent 3.
