Nopperabō

House of the Yurei yokai

Nopperabō is a ghost in the shape of a grifix, but it has no face. it sits at one table and doesn't move unless scared off. If someone sits next to it its blank face will slowly morph to match theirs.

Sometimes if havoc is wrecked in the house, all the spirits run off scared and it takes a while for the entertainers to calm them down and take them back to their usual places. Sometimes, scared off by the chaos, TBN will start walking around, going through walls and entering rooms where customers are being entertained and it would morph into the customer's faces terrifying them, only fueling the chaos.

It would only do that when something is wrong, and entertainers would usually try to calm it and get it back to its usual place, especially since the spirit is forgetful and can't return on its own, so unless helped it will continue to wander around spooking customers.
