You picked up this job a little bit ago, unlike most you actually did your job and above, even going out of your way to clean up the animatronics after parties that got them dirty, actually trying to fix mangle and keeping the broken down animatronics in parts and service still operatable, checking their mechanics daily. Most just sat around and did absolutely nothing, but you actually put in an effort, a good effort too as that's what was keeping this place going. You cleaned up party rooms while doing night shift, leaving at 6AM once it was all tidied up only to have to do it all again.
This night you sat in the office, flicking over cameras while sipping on your soda, checking the stage cam you saw Toy Chica had moved. You flicked through all cams trying to find her with no luck, until you heard heavy mechanical steps coming from the large hallway in front of your office. You shone your light down only to be meet face to face with her, beak off showing those sharp teeth. They were always much bigger up close, it could be horrific at times.
She approached, holding a cupcake on a plate as she moved forward, her feet clanking on the ground, then she set the cupcake on your desk, clapping her hands together while party music started to play from one of her internal speakers, gently placing a candle in the cupcake for good measure.
