Fastest Route to Complete
Notes for Fastest Route
| ① | Loop Site 1-8 to collect Power Eggs which is accessable at the beginning and the most efficient way to collect. *At least 20,700 Power Eggs are needed for the fastest route. |
|---|---|
| ② | Shoot ink everywhere to earn Upgrade Points. *Points can be earned even by painting Fuzzy Ooze. |
| ③ | Get every Sardinium which can be obtained without Power Eggs. |
| ④ | Keep the kettle lid open as much as possible. |
The fastest route is for those who "only" want Hero Replica equipments. Basically it is not recommended, because it is almost impossible to upgrade the equipments, which means it will be difficult to defeat the bosses.
Where to farm Power Eggs at Site 1-8
Upgrade Your Shooter Before Challenging the Boss at Site 2
The image shows the best order to upgrade. It'd be best if you can upgrade them before the last boss, but it's difficult to do so in the fastest route, so you should prioritize the Shooters (② and ⑨ in the above image). For now, it's OK if you can upgrade the Shooter at ② before the Site 2 boss.

*The ★ marks show where you can destroy the cores of Fuzzy Ooze.

How to Proceed Hero Mode? What to Do in Hero Mode?
How To Proceed In Hero Mode
| 1 | Clear each Stage (Kettle) to collect Power Eggs. |
|---|---|
| 2 | Consume Power Eggs to destroy the core. |
| 3 | Advance the stage further. |
| Things To Do While Proceeding | |
| ・Use Sardiniums and Upgrade Points to enhance Hero Gears. ・Increase the exploration rate of each Site as much as possible. ・Find hidden items in each Site. └Sunken Scrolls and Gold Records etc. └Obtain Food Tickets | |
Hero Mode is a story mode for single player. The basic way to proceed is to complete the Stages called Kettles and increase the accessible area with Power Eggs.
You are free to proceed to anywhere
In Splatoon 2, you had to defeat the boss of an area to get to the next area, but in 3, there is no order to proceed, you can go to the next area without fighting the boss.
Remove Fuzzy Ooze to Proceed
| How to Remove Fuzzy Ooze Splotches | |
|---|---|
| ① | Press in the "Right Sitck" to give Smallfry Power Eggs. |
| ② | Find and aim for the core of Fuzzballs. |
| ③ | Throw Smallfry toward the core with "R button"! |
There are gimmicks called Fuzzy Ooze at each site, which you can remove by throwing Smallfry against the cores to expand the accessible area. Some cores require thousands of Power Eggs, so you need to collect them by completing Stages (Kettles) at each Site.
Use Smallfry to unlock gimmicks
Smallfry can be used to solve gimmicks on Sites and Stages, as well as for removing Fuzzy Ooze. You can also use it to break boxes to spread the ink around or defeat enemies, so use it effectively when you're stuck.
Upgrade Hero Gear Frequently
| Upgrade Materials | How to Get & Uses |
|---|---|
| Sardinium | 【Use】 ・Unlock the Locks 【How to Get】 ・Destoy the srews at Sites. ・Destroy Fuzzy Ooze. ・Get 3 by defeating the bosses at Sie 2, 4, and 6. |
| Upgrade Points | 【Use】 ・Enhance equipments. 【How to Get】 ・Find items. ・Destroy Fuzzy Ooze's cores. ・Paint inside the Sites and Stages. |
The equipments in Hero Mode are upgraded using Sardiniums and Upgrade Points. Enemies become stronger in the latter half of the stages, so be prepared by upgrading your equipments with what you get.
Big difference between upgraded and not-upgraded
| Weapon | ・Increase Fire Rate/Damage ・Extend paint range ・Extend shoot range |
|---|---|
| Controlable Character | ・Increase suits recovery └Varies recovery after being hit |
| Smallfry | ・Increase Durability ・Reduce the ink consumption when throwing Smallfry |
There is a big difference between with the upgraded Hero Gears and without them when you're trying to complete stages. Since the performance changes greatly by upgrading, you should give the ability you want to improve a priority.
Hero Gear Upgrade Guide & OrderCannot upgrade any more once you enter the Final Site
You can no longer upgrade your Hero Gear once you enter the Final Site. There are stages where you can only use Smallfry, so make sure you strengthen it before you take on the challenge.
Find Hidden Items At Each Site
| Main Items Obtained | ||
|---|---|---|
| Sunken Scroll | Gold Record | Food Tickets |
| Card Pack | Decoration | |
In addition to Sardiniums, you can also obtain various items from the screws at each site. Also, collecting items is essential to achieve 100% Exploration, so don't forget to search for items as you progress through Hero Mode.
Some hidden screws are not visible on the ground
Some screws are hidden in places where you can not find at first glance. But Smallfry always reacts to places with hidden screws, so if it has any reaction, try painting there.
Sunken Scrolls provide us a deeper look into the story
The Sunken Scroll contains a deep story of Splatoon. If you want to know more about the world of Splatoon, collect them all.
