Splatoon 2: All Sardinium Locations | Weapon Upgrades Guide

Sardinium is the collectible you’ll need the most in Octo Canyon, the singleplayer hero mode of Splatoon 2. Why? Because collecting these little chunks of fish-shaped metal let you upgrade your Hero Weapons, unlock new sub abilities, or enhance your ink tank.

There’s no getting around it. If you want to use Sheldon’s Ammo Knights Enhancifier, you’ll need to collect plenty of these morsels. There’s one in every single level, and you’ll earn a free one for each boss fight. Considering there are only five boss fights, that’s not enough to get the best enhancements. That’s why we’ve put together a guide showing all the spots to grab Sardinium, including a gallery to help you spot them all.

All Sardinium Locations | Weapon Upgrades Guide

Sardinium might look like an ugly statue, but it’s actually an important resource for upgrading your Hero weapons in Octo Canyon. After completing the first boss, Sheldon will appear with his Upgrade Terminal. Here, you can spend collected eggs and Sardinium to purchase Hero Shot (or other weapon) enhancements.

There is one Sardinium collectible in each level, and you’ll be rewarded with a bonus Sardinium after every boss. Every hub also contains a single secret Sardinium piece, and they’re all worth getting if you want to truly enhance your vast Octo Canyon arsenal. Check out all the locations below.

Area #1: Tentakeel Outpost

Sardinium #1: Level 1: Return of the Octarians ~ Rescue the Zapfish ~ Reach the launch pad that’s mounted on a wall. Ink the wall and swim onto the high platform — the launch pad will appear after blasting the Shield Octarian.
Sardinium #2: Level 2: Welcome to Octopia ~ The Summer Wind Rises ~ At the third checkpoint, after swimming by the Squee-G, you’ll find a wooden wall with a launch pad mounted on the side. Ink the wall and swim to the roof to find three crates. Blast the crates to reveal a Sardinium!
Sardinium #3: Level 3: Sunset Octocopter ~ Dash and Jump ~ Reach the four ink pistons are after the second checkpoint. In the back-left corner, there’s a high platform with the collectible — use the ledge near the third checkpoint to reach it.
Sardinium #4: Boss 1: Industrial Toast ~ Into the Octo Oven ~ Rewarded for defeating the first boss!

Area #2: Suction-Cup Lookout

Sardinium #5: Suction-Cup Lookout Hub – Drop down to the bottom of the tower with the Level 6 door. There’s a small alcove filled with crates in the corner — blast it to reveal the sardinium.
Sardinium #6: Level 4: Enter the Octohurler ~ Let It Roll! ~ Right before using the second launch pad, look for the secret platform on the edge just past it.
Sardinium #7: Level 5: The Octopark ~ Stay on Your Grind ~ Beyond the sixth checkpoint, enter the long ink grind rail path. While riding the rails, the two will become three — stay on the left side, then jump onto the left, third grind rail to reach the high platform with a sardinium collectible.
Sardinium #8: Level 6: Octozeppelin Invasion ~ Time to Set Sail ~ Get to the second Octozeppelin Launcher and you’ll find the Sardinium close to the barrel where the Octozeppelins spawn. Blast the Octozeppelin as it spawns, then squid-form to the Sardinium before entering the launch pad.
Sardinium #9: Level 7: Back-Alley Cleanup ~ Suck It Up ~ If you’ve got an eagle-eye, you can see this Sardinium collectible from the fourth checkpoint. To actually get it, activate the ink grind rail at the fifth checkpoint. Use the grind rail to reach the glass platform with the solo crate containing a Sardinium piece.
Sardinium #10: Level 8: Spinning Campground ~ Ink Me Out, Ink Me In ~ Use the inkfurler past the second checkpoint to reach a new platform, then look in the far corner. There’s a metal grate below — reach it and shoot the crates to get a Sardinium.
Sardinium #11: Level 9: Octoling Strike ~ Riot in the Reef! ~ Smash the crates next to the Octoling’s enemy spawn point to find this Sardinium.
Sardinium #12: Boss 2: The Showdown ~ Fear the Octo Samurai ~ Another reward for defeating the boss.

Area #3: Beaker’s Depot

Sardinium #13: Beaker’s Depot Hub – Use the windmill switch directly right of the entrance, then splat the flying hook to get to the Level 13 door. Hop across the tall metal pillars to reach a tiny crate containing your first Sardinium for this area.
Sardinium #14: Level 10: Octoseeker Shakedown ~ A Midnight Stroll ~ After hitting the final checkpoint, blast all the crates behind the last launch pad that sends you up to the Zapfish exit.
Sardinium #15: Level 11: The Floating Garden ~ Chasing Heartache ~ Ink all the Tentakooks in the area with a small swarm of them to get both keys. One key opens the launch pad vault, and the other unlocks a square container with a Sardinium collectible. Try grabbing the special weapon at the top of the ramp to make splatting these jerks easier.
Sardinium #16: Level 12: Octo-Resort Spring ~ Everybody Bounce ~ Hop across the bouncy conveyor belt area to reach the ink-spraying Octarian. There’s a high platform on the right with a Sardinium crate here.
Sardinium #17: Level 13: Dancing Floors ~ Ink Switcheroo ~ At the second checkpoint area, there’s a long series of steps you’ll need to climb to reach the launch pad, with a platform to the left of the launch pad exit. Hit the ink switches and quickly climb up and spray the inkable wall so you can climb up and get the Sardinium.
Sardinium #18: Level 14: Parking Garage ~ Drive to the Finish ~ Near the end of the level, you’ll reach a battle arena with Octolings. Before leaving through the vault exit, look in the back corner for a blocked-off area. Use the car to hop over and into the alcove to get the Sardinium.
Sardinium #19: Level 15: Octoling Assault ~ Pump Track It Up! ~ Follow the path to the right of the Octoling Spawn to find a tough, taped-up crate containing your Sardinium.

Sardinium #22: Level 16: Secret Bowling Alley ~ Rollin’ through the Ink ~ At the second checkpoint, you’ll reach an OctoSniper section. Look for the metal grate you can slip through in Squid-form, on the left edge of the second set of OctoRollers.
Sardinium #23: Level 17: Octocommander Fortress ~ Child of the Battlefield ~ Around the second checkpoint area, use the rotating platform and hop onto the ink grind rail. Ink up the wall to the left to find a Sardinium.
Sardinium #24: Level 18: Towering Heights ~ Climb and Slide ~ At the end of the level, you’ll have to ride a moving platform while Octarians spawn all around. When the platform reaches a corner, there’s a Sardinium floating above the center spong. Ink the sponge to reach it.
Sardinium #25: Level 19: The Experimentorium ~ Floaty Fun ~ Found on the left-most launch pad path from the start of the stage. You’ll reach a large switch you need to ink. After activating it, move left and shoot an optional switch — a platform will lower. Squid-form jump to the tiny crate containing a Sardinium.
Sardinium #26: Level 20: Propellerland ~ Rubber Parasoles ~ After getting both keys, ride the ink propeller platforms. You’ll eventually reach a large ink propeller platform that moves right when you shoot it — at the end of the track, there’s a Sardinium marked with three fried rings! Shoot the ink valve to reach it.
Sardinium #27: Level 21: Octolings Ahoy! ~ Moray Twilight ~ Once again, the Sardinium is found in a big crate right below the enemy’s Octoling Spawn, on the opposite side of the map.
Sardinium #28: Boss 4: Sanitazium ~ The Octo Shower ~ Your fourth Sardinium reward for defeating the area boss. Only one more boss to go!

Sardinium #30: Level 22: Underground Expressway ~ Octobrush with Danger ~ After splatting the Octocommander, you’ll find a TentaKook running circles in a small path at the base of a big cube. Ambush the Tentakook to collect the key and unlock the vault at the top of the cube.
Sardinium #31: Level 23: The Octogalaxy ~ One with the Cosmos ~ Just after you complete the area with the Ink Turret, you’ll reach a long series of suspended ink grind rails. Stay on the rails and ride them all the way to the end of the path, swapping rails as you go, to reach the fried rings and a Sardinium reward.
Sardinium #32: Level 24: Transfer Junction ~ Intersection of the Soul ~ At the start of the stage, past the very first checkpoint, ink up the wall to your right. The Sardinium is floating on the back end of the wall, so be careful when you drop down to grab it.
Sardinium #33: Level 25: Platform Madhouse ~ Please Mind the Gap ~ Past the pair of OctoCommanders, there’s a tall moving wall you’ll need to climb with metal grate platforms. At the top, look down to find a hidden alcove below.
Sardinium #34: Level 26: Paradise Lanes ~ Get the Ball Rolling ~ From the first checkpoint, drop onto the ramp covered in enemy ink below. Immediately turn around to find the Sardinium crate.
Sardinium #35: Level 27: Octoling Workout ~ Forge Those Mussels ~ Near the hero spawn point, find the shoppe roof and ink it up (the one near the center, on the hero side, with a sign hanging outside the window) to reveal a secret Sardinium crate.
