The kettle is located on a high platform directly to the left of the entrance to Area 3. Various obstacles including climbing up walls have to be passed to reach it, however.
Twice a year, the Inkopolis Collection fashion show captures the hearts, minds, and wallets of the city's youth. Is there no room in these creatures' minds for anything but battle and fashion?
Location: At the second checkpoint, under the invisible ramp. When you hit the second checkpoint, the crate containing the Scroll is completely visible, however, it is obstructed by a large, invisible ramp. Shoot the ramp and splat the oncoming Octoballs. Stand at the top of the ramp and jump off the side, angling your momentum toward the underside of the ramp. If done correctly, you should land right next to the crate containing the Scroll.
Armor
Location: Breaking the center crate wields armor. The crates on the left and right hold Power Eggs. The armor is helpful to get across the group of Octotroopers and get to the Zapfish.
