Just click the Green Flag and watch the lights flicker and while the Inner Tera comes out at night...
Thanks to @kuswerdz for the original concepts for Scratching 'Til 6:00 REMASTERED. I wanted to make a more scary-ish animatronic based on his, and I thought this wasn't too bad. I also tried to make it look like the lights flickered but didn't do too well I kind of based Nightmare Tera's arms on Withered Chica from FNaF 2
