Ewok

Appearance:
Ewok is a mask, somewhat similar to Sunrise from FNaF: Security Breach. She is attached to a ink-black, featureless mannequin. When she detaches and attacks you, white pupils appear in the dark sockets.

Game Mechanic:
She sits in the Boiler Room on Cam 5 as a wax statue possessed by a mask. When the building is over 90 degrees, she will start to melt and lose her form. If she melts completely, her mask will leave the boiler room and come to kill you. The right door can temporarily stop her.

If the power runs out then she will appear by the right office door, a tune plays before it cuts. This results in you also getting jumpscared by her.

Voice Lines:
"Between life and death, you're stuck between a valley of rage."

"Now who's the one playing with power?"

"Open your mind, it is time our worlds collide."

Trivia:

 * Ewok's voice lines are all references to EwokShawoddy's animations with Knife Party's songs, including Rage Valley. Power Glove, and Boss Mode.
