Muffler Person

Muffler Person is an Effect-Get NPC that can be found northwest from Clover World.

Features
They appear to be invisible, with only their scarf seen. Interacting with them will give you the Muffler effect.

An interesting feature about them is that, when equipping the Range effect and using it on them, their scarf will fall down onto the floor, implying that the player has killed them. This death is permanent, as they can never come back, even waking up or re-entering the Clover World.

The Muffler Person can also be found in the Umbilical Cord Maze. However, their appearance is visible this time. They are found leaning/sleeping on a cord that has been tied up as a ribbon. If the player attempts to harm them with the Drip Stand effect, Yakitsuki will nod no, making it impossible to kill them.
