Treasure

The treasure is a key item constructed in Return of the Mammalians in.

Description
The treasure is a large tool assembled from three parts: frame, motor, and blades. The fully assembled treasure resembles a hand-operated motorized tiller with four scissor-like blades and five saw blades, for a total of nine blades. The treasure's blades are golden, the frame is blue, and the motor part is silver.

Return of the Mammalians
The player must defeat Deep Cut members Frye, Shiver, and Big Man in order to obtain the treasure's three parts, as Deep Cut wants the assembled treasure for themselves.

After collecting the three parts, the treasure is then assembled into a tool by the New Squidbeak Splatoon members Callie and Marie, with the help of the Captain. The Captain uses the assembled treasure to remove a colossal mass of Fuzzy Ooze that blocked the path to the Alterna Space Center, though injures themself in the process.

As the New Squidbeak Splatoon make their way towards the Space Center, Deep Cut re-appears to fight them for the treasure, but Marie offers it to them for free after having already used it, causing Deep Cut to apologize and make Marie their boss. When asked about it in between and, Deep Cut reveal they planned to sell the treasure to help struggling citizens in Splatsville.

Trivia

 * The treasure functions similar to the thangs from Octo Expansion, as both are pieces of a larger tool, collected in special missions, kept in the campaign's central area, and assembled in order to reach the final boss area. Unlike the thangs, which ultimately served the antagonist's purposes, the treasure is used to help Agent 3 and the New Squidbeak Splatoon.
 * When the treasure is wielded by the Captain, their tentacles glow and flutter as if they are wielding a special weapon.
