Flooder

"Flooders... These things can't be destroyed."

- Cap'n Cuttlefish

Flooders are Octarian machines that appear as enemies in Octo Valley, Octo Canyon, the Octo Expansion, the Shifty Station Flooders in the Attic, and Return of the Mammalians.

Description
Flooders are large, cylindrical machines held up by four legs with one wheel each. They have a flat top and two purple "eyes" with a nose-like knob between them. Encircling the top of each Flooder is a ring of light purple lights. Flooders vary in height, with some (known as Big Flooders) being taller than others.

Flooders constantly shower Octarian ink from their undersides, coating all surfaces underneath them and instantly breaking the player's armor or splatting them if they are caught in the torrent. Flooders themselves cannot be splatted. They are restricted to move along perpendicular pathways, but upon noticing the player, they will rush towards them to the best of their ability, as indicated by a red laser that comes out of their eyes and points at the player (although this laser is harmless and serves only as an indicator). The tops of Flooders function as platforms and can be inked and stood on, and may have an Octarian, crate, or vault present on them. A Flooder cannot spot the player if it is under them, including if the player is on top of it. In Return of the Mammalians, throwing Smallfry at a Flooder will cause Smallfry to latch onto the top and disable it by repeatedly attacking it, preventing it from moving and spreading ink; however, it will return to normal when Smallfry leaves it.

Tips

 * Players are able to pass by through Flooders. To do this, if there is Flooder moving closer, it can be side-hopped with momentum. Without momentum, it is not possible to successfully get past Flooders. A result is falling out of bounds or instantly dying by standing under an active Flooder.
 * Using this strategy, it can also be used as a shortcut.
 * In Splatoon 3, Smallfry can be thrown at a Flooder, causing it to stop spraying ink as long as Smallfry attacks it.

Trivia

 * When playing Flooder Junkyard as a Kraken via the Inkling Squid, Flooders cannot harm Agent 3 and can simply be passed under.
 * In Marina's chat room, in the Octo Expansion, it is revealed that Marina designed the Flooder when she was a combat engineer for the Octarians.
 * The Griller is a Boss Salmonid that resembles the Flooder in both design and function. This may be related to the fact that Octarians are known to trade their technology with the Salmonids in exchange for Power Eggs.
 * The Big Flooder was named in Ink It Station.
