The Kettle for this mission can be found on a platform in the near left corner of Beaker's Depot. To get to it, jump through a grate near the ride rail that leads to the lower level of the area. Walk up a ramp to find the kettle.
Beginning Area[edit]
Take the launchpad immediately in front of the spawn. Walk along the path, breaking the crates and splatting the Octotrooper in the way, and use the dash track to get up the wall. Proceed along the path and chase the Tentakook ahead to the dead end and splat it. Pick up the key when it drops, head to the vault and take the launchpad to the first checkpoint.
Checkpoint 1[edit]
There is a wide passage, with three ramps to the sides. There is a Octotrooper on top of each ramp, and the Tentakook will take the ramps. Follow the Tentakook's trail and splat the Octotroopers or take the straight path and risk losing track of the Tentakook. Force it to the end of the path and splat it to obtain the key for the vault and take the launchpad to the next checkpoint.
Checkpoint 2[edit]
Break the crates and splat the Octotrooper next to the block ahead. Climb up the block and splat the two Tentakooks on the circular path around the block. One of them has the key to the vault locking the launchpad to the next checkpoint.
Checkpoint 3[edit]
Go straight, splat the Octotrooper and head to the crates. Break the crates and splat the Shielded Octotrooper behind them. Climb up the block to the right and splat the two Octotroopers there. Take the ride rail to the next checkpoint.
Checkpoint 4[edit]
Go along and chase the Tentakook down the path. There is an Octotrooper halfway through, and two more at the end. Splat them and the Tentakook there, take the key from the Tentakook and unlock the vault holding the launchpad to a small platform. Take the Ride rail there to the next checkpoint.
Checkpoint 5[edit]
There is a large inkable loop with lots of turns and a Tentakook running along the loop. There are gratings for the player to chase it down. Splat it to get the key and take it to the vault to use the launchpad to the next checkpoint.
Checkpoint 6[edit]
Climb up the block ahead and fight the Octotrooper and Shielded Octotrooper patrolling on a small rectangular loop. Continue along the path and splat the Octotrooper in the way and get to the final checkpoint.
Final Checkpoint[edit]
Continue along the path and chase the Tentakook ahead. Take another left turn and enter the huge area ahead. The area consists of 6 island blocks dividing the area into three vertical and four horizontal paths, ramps to help trap Tentakooks, a set of slopes at the far end for the Tentakooks to climb up and jump off, and two stationary Octotroopers guarding the area. Two out of the six Tentakooks carry keys, which opens vaults on the island blocks. The launchpad is in the larger vault, which takes the player to the Zapfish. Chase down the Tentakooks which will eventually end up trapped in the far right corner, where they can be easily splatted.
