Lair 14: Parking Garage
During your advance around the Octosniper, look for this hidden platform directly beneath the checkpoint—the stage’s Sunken Scroll is waiting here.
Lair 15: Octoling Assault
The Sunken Scroll is locked in this box on the foam pit near the Octolings’ base. You must retrieve one of the two keys before you can open it. Either key opens the box. The other key can be used to open the locked box containing the Splashdown special.
Area 04: Slimeskin Garrison
Locate the green balloon beneath Lair 18 to start the chase for the area’s Sunken Scroll. The Hero Shot is more than adequate for hunting down all of these balloons. After popping the first balloon, follow the green arrows to find the next balloons in the sequence. The final balloon floats beneath the grate next to Lair 18. Step out onto the nearby Inkfurler and shoot the balloon to release the Sunken Scroll. Next, stay on the Inkfurler and ink the wooden wall beneath the grate. Squid-jump over to the wall and swim up to the grate to retrieve the Sunken Scroll.
Lair 16: Secret Bowling Alley
Use the nearby cannon to ink the wall just beneath the narrow path where the massive Kingpin Octoballers drop. Next, swim up to the inked wall and partway up, waiting for the next Kingpin Octoballer to pass. When the path is clear, swim up to the narrow path and toss a Curling Bomb straight ahead. Swim directly behind the Curling Bomb and squid-jump toward the small platform on the right to avoid getting splatted by the next Kingpin Octoballer to retrieve the Sunken Scroll.
Lair 17: Octocommander Fortress
Look beneath the final checkpoint’s platform to locate this well-hidden Sunken Scroll, stored in a small orange crate. Be sure to grab it before traversing the final set of rotating platforms.
Lair 18: Towering Heights
After clearing out the three Octosnipers, drop down to this grated platform. Here you find a small crate containing the lair’s Sunken Scroll. While you’re down here, take note of the large orange crate on a neighboring platform it contains a ticket.
Lair 19: The Experimentorium
Sunken Scroll sits atop a high platform, just out of reach. You can cause it to drop by hitting a hidden Splat Switch. Start atop this wall, aiming toward a distant Grapplink. Shoot the Grapplink to launch yourself forward. As you fall, fire again to hit a second Grapplink, followed by a third and fourth. After striking the fourth Grapplink, turn to the left to hit a Splat Switch, which causes the Sunken Scroll to drop to a platform near this area’s return launchpad. If you miss the Splat Switch, you can use the nearby launchpad to return to the top of the wall where you started the sequence. You’ll eventually need to hit five consecutive Grapplinks to escape this area and retrieve the Sunken Scroll.
Lair 20: Propellerland
After accessing the platform with the second vault, turn around and shoot the Propeller. As the lift rises, look for a small Splat Switch on the edge. Shooting this Splat Switch causes a narrow walkway to appear, beyond the second vault. Step out onto this narrow walkway to grab the Sunken Scroll.
Lair 21: Octolings Ahoy
The Sunken Scroll is stored in a crate on this yellow grate. Drop down from the platform above after freeing the nearby Mini Zapfish.
Area 05: Cephalon HQ
Equip the Hero Charger and start on the central platform where you initially entered, looking out toward Lair 25 board one of the nearby saucers as it passes by. The first Sunken Scroll balloon is floating near the large tentacle, beneath Lair 25 pop it with your Hero Charger to begin the chase. Stay on the saucer and follow the green arrows to the next balloons in the sequence, shooting them with the Hero Charger. As the saucer circles back toward the central platform, jump off and shoot two more balloons. The final balloon is floating on the opposite side of the center platform, between Lairs 23 and 27.
Shooting it causes the Sunken Scroll to appear and fall onto an invisible platform. Ink the area around the Sunken Scroll to reveal two neighboring platforms nearly connected by a drawbridge. Board one of the adjacent saucers and ride it toward the freshly inked platforms to retrieve the Sunken Scroll cross the inked drawbridge when it’s down, then squid-jump over to the scroll’s platform.
Lair 22: Underground Expressway
This Sunken Scroll is located on an invisible platform directly beneath the Zapfish. While ascending the ramp toward the Zapfish, fling ink over the right side to reveal the invisible path below. Drop down onto this path to recover the Sunken Scroll. Once you retrieve it, continue inking the invisible path to return to the platform patrolled by the Industrial Squee-Gs.
Lair 23: The Octogalaxy
The area near the Sunken Scroll features a set of colorful pillars fitted with extending and retracting Ink Pistons. Ride a Ride Rail toward the first column, but be ready to enter squid form to duck beneath the first extending Ink Piston. Immediately after passing the first column, leap to the adjacent Ride Rail to the right. This Ride Rail leads to a small, isolated platform guarded by a Shielded Twintacle Octotrooper. Land atop the wall in the center of the platform and fire down on this foe to circumvent his shield. Once the platform is clear, smash the nearby crate to retrieve the Sunken Scroll.
Lair 24: Transfer Junction
Eliminate the Octotroopers on this platform, then peer over the edge to spot a sponge below—ink the sponge to expand it. Drop down onto the sponge and turn around to locate the Sunken Scroll hidden within this alcove beneath the platform.
Lair 25: Platform Madhouse
Shoot the small diamond-shaped Splat Switch on the edge of the Zapfish’s platform to reveal a hidden launchpad atop the moving platform. This launchpad leads to a distant platform occupied by an Octostamp DX. Lure this enemy forward, then sidestep as he face-plants. Use this opportunity to ink his side and swim up to another launchpad on his back, which leads to a small platform with a high stack of crates. Smash all the crates to retrieve Power Eggs and this lair’s Sunken Scroll. Use the launchpad beneath the crates to return to the Zapfish’s platform.
Lair 26: Paradise Lanes
Navigate toward this platform’s launchpad, careful to avoid the stacks of Octoballers rolling down the narrow lanes. Before using the launchpad, turn to the orange crate on the neighboring lane. Wait for the latest set of Octoballers to pass, then ink a path before squid-jumping across to the adjacent lane. Rush to this ledge and smash the crate to grab this lair’s Sunken Scroll.
Lair 27: Octoling Workout
The Sunken Scroll is concealed within an invisible crate, near this central catwalk.
Ink this raised platform to make the crate appear, then destroy the crate to retrieve the Sunken Scroll.
