Floating Sponge Garden

The Floating Sponge Garden is the fifth mission available in single player Hero Mode.

Octo Valley
After the player clears Boss 1 Squish, Squash, Smash... The Mighty Octostomp!, they gain access to Area 2 via an Inkrail. To access this level walk up right into a large crater on the ground and shoot the invisible kettle to enter.

Beginning
Fall down and spray the Sponge Block until it is as large as possible and then swim up it.

There are two (insert unknown enemy here) so shoot them and spray another sponge, swim up.

There are two Octotroopers behind a wall. Shoot them to reach a checkpoint.

Checkpoint 1
Spray the sponge and swim up to see another sponge to swim up, but this time an Octotrooper is waiting on a platform above. When he turns around, swim up and shoot him and a box containing Power Eggs and continue up two more sponges and a (jump pad?).

Checkpoint 2
Jump down and spray the ramp for some more Power Eggs and swim through the fence to see two Octoballs.

Simply spray the ground in front of them so they are stuck and shoot them while they're in your own paint to kill them.

Swim up another sponge and shoot a vertical wall with more Power Eggs, swimming up it to progress.

Checkpoint 3
There are three sponges in a line, and then three more Octoballs. Use the same method as before to dispose of them.

Shoot down a balloon with more Eggs and use the (jump pad?) that will only appear after all three Octoballs are gone.

Checkpoint 4
Either dispose of the two (insert unknown enemy name here) or quickly swim up the sponge before they can blow it up.

There is another inkable vertical wall that is being guarded by two more Octotroopers. Either shoot them first or shoot the wall and go past them to reach another (jump pad?).

Checkpoint 5
There are 6 sponges in front of you and 3 Octocopters.

You're gonna want to spray each Sponge Block and once you get to the second row of two sponges one of the Octocopters will take notice of you and come closer. Shoot it as soon as possible and by then the other two must've noticed and take them out as well.

When you reach the third row with three Sponge Blocks, there are two walls with an Octotrooper strolling behind them.

Spray an area where he isn't looking at, jump over, and take him out.

Shoot and swim up the ramp with more eggs.

Final Checkpoint
There is a (missile turret) to swim into and five Sponge Blocks are visible, four of which have Octotroopers on them and two Octocopters. Just shoot at your heart's content and once all enemies are gone and each block is large enough, spray the floor beneath you near one of the blocks and swim jump onto the block and each remaining block until you've reached your Zapfish.

Amiibo
There are 2 other versions of this level that can only be played through their respective Amiibo. Each Amiibo uses a different weapon for the stage. The Inkling Girl challenges revolve around a Splat Charger and the Inkling Squid uses the same Hero Shot from the normal campaign, except in this stage there is a limit on how much ink you have.
