Brain Strainer

The Brain Strainer is headgear in Splatoon 3.

In Splatoon 3, it is a 0-, 1- or 2-star item produced by Grizzco and comes with a random primary ability generated when it is received. It is only available as a reward from Salmon Run Next Wave as the monthly gear for November 2022 or in a Pink Capsule. It cannot be ordered through Murch.

Appearance
The Brain Strainer appears to be a spaghetti strainer with a red and blue wire coming out from it, small blinking lights coming out of the sides and an object that appears to be an antenna on the top. The strainer is attached to the player by a band connected to the strainer's handles.

Trivia

 * This device resembles the Aura Video-Analyzer from the first Ghostbusters movie. It also bears a resemblance to the brain-wave analyzer first featured in Back to the Future, being one of 3 pieces of Grizzco headgear that potentially resemble costumes seen in the Back to the Future series, the others being the Lo-Vis Visor and the Bream-Brim Cap.
