Ink Piston

"Ink Pistons. I don't recommend you touch those."

- Marie

Ink Pistons are obstacles found in Octo Canyon, the Octo Expansion, and Return of the Mammalians. They shoot a ray of ink into the direction they are facing, dealing enough damage to either break the player's armor in one hit or immediately splat them if they are without armor. Ink Pistons are completely indestructible.

A version of this obstacle called Ink Sticks, which are always extended, appears in the Octo Expansion and Return of the Mammalians. Ink Sticks can knock the player off of ride rails while Ink Pistons only break their armor.

Description
Ink Pistons are Octarian machines that periodically release powerful rays of ink. They appear to have faces made up of three bolts, two making the eyes and a bigger one making the mouth. They can be seen bolted to a wall or in a floating tank, placed horizontally or vertically.
