Boss Kettle Entrance
Acquiring six 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.
Sheldon Request
Sheldon has selected the Hero Charger for this boss fight, and it’s an excellent choice, given the nature of this encounter. You must rely on the Hero Charger’s long-range capability to splat the Octocopters carrying this boss around. Curling Bombs are also effective, allowing you to quickly ink and swim across the arena in an effort to escape the Octo Shower’s deadly attacks.
Round 1
As soon as the battle begins, the Octo Shower targets you with a red laser—this is your cue to move. Fire a line of ink and swim through it to prevent getting splatted by the Octo Shower’s opening long-range attack. Immediately 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. You can usually eliminate two Octocopters before the Octo Shower flees. Follow the Octo Shower and ascend the adjacent platform to resume your attack.
Once all three Octocopters have been splatted, the Octo Shower crashes to the arena floor and a tentacle is exposed. Take aim at the tentacle and continually strike it with the Hero Charger until it explodes—it only takes two fully charged shots.
Round 2
The Octo Shower comes back stronger in the second round, this time hoisted by four Octocopters. As soon as the round starts, 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 you’re taking aim at the Octocopters, the Octo Shower continually launches missiles in your direction. These missiles move rather slowly, but keep an eye on them and be ready to move if they get too close. Don’t get greedy—even if you have a clear shot, it’s better to retreat than to get splatted by an incoming missile. 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.
Round 3
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. The path to Area 05 is now open!
