Area 03: Beaker’s Depot
Boss Battle: The Neo Octostomp
Collect all 6 Zapfish, the area’s Boss Kettle opens. Use your Hero Charger to hit the Grapplink and reach the kettle’s neighboring platform. From there you can activate a Ride Rail circling the Boss Kettle platform. While riding the Ride Rail, shoot one of the two Grapplinks above the Boss Kettle to gain access.
Octostomp has returned, wastes no time, rushing toward you at high speed. Move laterally to avoid getting run over. Consider tossing a Curling Bomb to the side and swimming along its ink trail to evade this opening attack.
The Octostomp lands face-first on the arena floor following his initial charging attack, exposing a tentacle on his back. Ink the side of the Octostomp and swim to the top. Shoot the tentacle on the Octostomp’s back until it explodes.
Octostomp assumes a new persona the Neo Octostomp. This is more than a simple name change; it also marks a change in tactics and capabilities. The Neo Octostomp is also equipped with a massive head mounted cannon capable of rapid fire. Use your Curling Bombs to create an ink trail, and swim forward to prevent getting hit by the Octostomp’s cannon. The Neo Octostomp is incapable of charging you at high speeds while wearing his coat, but he occasionally jumps up and performs a face-plant in an attempt to splat you. Stay out of his way as he jumps up, and look for opportunities to target the black buckle on his face this buckle holds his coat on. Keep hitting the buckle until it’s destroyed, which causes the coat to fall off. Watch for more charging attacks once the Neo Octostomp’s coat is removed—be ready to dodge-roll out of the way. Wait for the Octostomp to fall on his face, then ink his side and swim up to his back to attack the exposed tentacle once more.
Now much wider, featuring two additional face panels. This makes evading his opening charge attack extremely challenging, even when dodge-rolling or using Curling Bombs. If necessary, retreat to the perimeter of the arena the boss can’t access the outer ledge. Following the opening charge attack, the Neo Octostomp performs a series of face-plant stomp attacks. Once again, the coat prevents you from inking his sides. Rush to close range and shoot the buckle holding his coat on when he’s standing upright.
Destroying the buckle on the Neo Octostomp’s face causes his coat to fall off, restoring him to normal size. Still, be ready to evade more fast-moving charge and stomp attacks. Wait for him to face-plant, then ink his side and swim to the top, shooting the tentacle on his back one last time. That does it for the Neo Octostomp.
After the boss explodes, collect the Sardinium and Zapfish to complete the battle.
Area 04: Slimeskin Garrison
Boss Battle: The Octo Shower
Acquiring 6 Zapfish unlocks the area’s Boss Kettle. Proceed toward Lair 19, then turn right atop this platform and cross the nearby Dash Track to jump toward the distant Bounce Pad there’s a grate directly above. Bounce upward in squid form to pass through the grate, and approach the Boss Kettle to start the battle.
As soon as the battle begins, the Octo Shower targets you with a red laser. Fire a line of ink and swim through it to prevent getting splatted by the Octo Shower’s opening long-range attack. Move to the central tower and swim up the side. The Octo Shower is carried by three Octocopters. Take aim at one of the Octocopters and splat it with your Hero Charger. The goal of this round is to eliminate all three Octocopters. After splatting one Octocopter, take aim at the next one before the Octo Shower retreats. Once all three Octocopters have been splatted, the Octo Shower crashes to the arena floor and a tentacle is exposed.
This time hoisted by four Octocopters. Rush for the center platform to prevent getting splatted by the Octo Shower’s new rapid-firing cannon attack. Toss a Curling Bomb and swim through the ink until you reach cover. Following the attack, climb the center platform and go to work on taking out those four Octocopters. The faster you can eliminate the Octocopters, the sooner the round is over.
After eliminating an Octocopter, the Octo Shower counters with a linear shower attack, spreading a wide swath of ink across the arena. Move perpendicular to this attack to ensure you’re not caught in the downpour. For best results, toss a Curling Bomb and swim along its ink path. While taking aim at the Octocopters, the Octo Shower continually launches missiles in your direction. Continue taking down Octocopters until the tentacle is exposed once more—splat the tentacle wiggling atop the Octo Shower to start the third and final round.
Be ready to move at the start of the third round, as the Octo Shower opens with a powerful Sting Ray attack. This beam of concentrated ink can pass through cover, so there’s nowhere to hide. Instead, your best option is to keep moving, traveling perpendicular to the attack. As in the second round, the Octo Shower is carried by four Rocket Octocopters. When you’re not dodging attacks, climb to the nearest platform and open fire with your Hero Charger. Just remember to dodge the incoming shower attack after eliminating each Octocopter. In addition to the new Sting Ray attack, the Octo Shower performs all attacks from previous rounds, including the cannon and missile attacks. Stay on your toes and be ready to dodge. Unlike with the Sting Ray, you can hide behind cover to evade the cannon and missile attacks. Keep up the pressure until all four Octocopters have been splatted, causing the Octo Shower to crash.
Take aim at the tentacle one last time and hit it repeatedly until it explodes. Following the Octo Shower’s defeat, gather the Sardinium and Zapfish to complete the battle.
