This time when he pulled into the parking lot, Sans saw the silhouette of a body lying on the ground, assumingly dead. What a great way to start a night, am I right? So Sans creeped into the building, suddenly aware of the danger of his job. The phone voice started talking earlier than Sans thought before. It recited the exact same speech. All the animatronics were in their rightful place on stage, nothing to worry about there.
The rest of the night was fine, and Sans finished his first shift in no time. On his way home he heard a story on the radio about how monsters have been mysteriously disappearing. Perhaps the dead body in the parking lot had something to do with that story. After his night of work, Sans slept better than he ever has before, which is incredible considering he sleeps literally every day while "watching" for humans.
Later that night, Sans woke up to go back to the pizzeria since he wouldn't get paid at all until the end of the week. The body from earlier was gone. Hopefully someone cleaned it up, Sans thought. The back door wasn't open like it had been the previous shift. So Sans walked around the building to the front to see that the front door was wide open. Someone else probably just left their shift and left the door open. Yeah, that's what happened.
"Hello, hello! So, uh, if you're hearing this, then you made it to your second night. Congrats!" It was the phone guy again. Sans followed the voice again, since he didn't know how to navigate through the ENTIRE building yet. During his search for the office, Sans stumbled into the main stageroom. The chicken was gone, and the bear was staring at Sans. Now added to the list of things to do was not get killed by the chicken! At this point, Sans was just walking around like an idiot.
"You might wanna check out Pirate's Cove, or else Foxy will make you walk the plank! He tends to be more active on the second night, so watch out." Phone Guy sounded closer than when he first started talking, so Sans had made at least some progress.
After what felt like another half an hour, the office was finally in sight. Sans checked his watch, and it was 3 AM already. It took him three whole hours to get to the office. Once he settled in, he checked his cameras. The bunny was missing now. One of the cameras showed the chicken staring at Sans. Okay, well staring at the camera, but its almost the same thing.
"THE POWER! I FORGOT!" Sans yelled a bit too loudly. The power level was at ten percent. And there was still two hours left until Sans's shift was over.
