Treasure
From Inkipedia, the Splatoon wiki
The Treasure is a key item constructed in Return of the Mammalians in Splatoon 3.
It is a lawn mower-like tool assembled from three parts: handle, motor, and blades. The player must beat Deep Cut members Frye, Shiver, and Big Man in order to obtain these three parts, as they want it for themselves. The Treasure is then assembled by New Squidbeak Splatoon members Callie and Marie, with the help of the Captain. The Captain uses the Treasure to remove a colossal mass of Fuzzy Ooze which was blocking the path to the final boss area, the Alterna Space Center.
