The events of the gameplay literally happens after about 3 weeks of the destruction of Billy's, Mallory spotted the debris one day and tried to take a closer look at the outcome from almost a month prier. Once she was in the underground storage of the place, the hole she came in collapsed on itself with the only source of air being a very small vent on the wall. She may have everything to survive over the week until Will and Billy get back from vacation, she was told to wait until they get back to Georgia hence they don't want to waste their time over in Ohio, although at the same time, they don't want anything bad happening to her, so Will then told her how she could defend herself if the clones survived, in which they did. The three evil clones were very fractured and looked very weak, but apparently they're stronger than you think, it's because of Death's powers on these clones so they wouldn't be like weak zombies. That don't work at all for Death, he makes them stronger than they have ever been before. When Billy and Will finally got back from their vacation, they quickly went to the debris and get Mallory out of there once and for all. However, they couldn't do it alone. Dennis, Crash, Mr. Bear, Jessie, Tawna, Coco, and Ray all wanted to help out as well because they have been pretty good friends with the guys, especially Billy since he's pretty easy to get along with. They all managed to get Mallory out of the debris at long last, but Broken bit Billy on his arm while all of this was happening. It results in Billy getting very sick with the Edgor Virus which is the main thing that makes Billy sick in the third game of the series.

Characters: (Human characters are based off of irl people I actually know.)

Mallory: As said, she was looking at the debris of the funhouse until she gets trapped until Will and Billy return from vacation.

Zombie Pinstripe: There's been a reason why some Crash characters are in the series although Pinstripe is the only enemy that can actually kill you like everyone else. Before he came back as a zombie, about a week ago when Billy, Dennis, and Crash were looking for Tawna. They expected that she was at Pinstripe's place, when they got there, it got pretty ugly. Pinstripe was bragging and lying about how Tawna looks him more than Crash, this causes him to breakdown in sadness in which Billy gets really angry because of the nonsense coming out of Pinstripe's mouth. He grabbed Dennis' gun and shot him a few times until they learned the truth about Tawna.

Broken: An upgraded form of Grim but as a zombified husky with additional arms and can crawl like Mangle.

Glitch Billy: Invert Billy's final form in the series in the custom night with Tawna in FNaB2. When he's on the cameras, he causes hallucinations in which could freak anybody out.

How Tawna disappeared in the FNaB series:

She was actually captured and frozen by Cortex and Death in which was a plan to make Crash suffer. The main thing that brought up Tawna for Crash was about seeing her in a dream. He thought that they were both finally reunited until he woke up. (Trust me, I go through that pain before. It hurts like hell) Coco informed Billy about what happened with him hence they are both pretty good friends since FNaB 1 when she helped out with the cameras.

Tawna was later found and unfrozen thanks to Billy, but it took a little while for her to get up and finally be reunited with everybody.
