Mutant

Mutant is an Effect Get NPC that can be found in the left side of the Storage.

Features
It appears to be a cat-like mutant due to the cat-shaped ears it has. On it's face is what it appears to be a mouth with fangs, and a tattoo on their left arm (in their perspective). Interacting with the Mutant will grant you the Guinea Pig effect.

They will die like every other usual NPC when hit with the Drip Stand effect.
