Mono and Six repeated that damned cycle for who knows how long. The young boy would 'remember' the events of the previous loop as he hung from Six's grasp, just be abandoned and for his adult form to be released, himself soon to fail to end the cycle.

Neither of them could've known 'deja vu' might be a variable. One too many runs later, Six figured something was wrong, something on their path wasn't falling in place.

She pulled him up, had their first talk, and began their trip to the Maw.

Now they're running out of food. No matter how harshly they rationed and thin they got, they were getting low on preserved vegetables and corpses. So, Mono grasped Six's hand and put the other on the nearest TV. It hummed to life and they fell through space.

Welcome to Freddy Fazbear's Mega Pizzaplex; where fantasy and fun come to life, sentient AI run amok, nobody is safe, agony is restless, and secrets don't keep!

There's plenty to find, places to hide, serial killers to evade, and mysteries to be solved. The Puppet and Rabbit have left the pieces for Six, Mono, and Gregory. Should they survive long enough to assemble them, they might find something wonderful.

Let's have some fun.
