I haven't done any of these myself yet, but after thinking for a bit I came up with these.
Give it a creative name, and make sure it is possible, interesting, hard, or even fun. This can be fun and can help pass time while we wait for Custom Night! Well, since this game isn't getting an Update 3 and it's pretty much pointless to continue playing after unlocking all trophies, I'm making a thread where you can share challenges (examples: fixed party presets, completing things in an alotted amount of time, etc). If it breaks any rules feel free to take it down. I had initially posted this on the FNaF World discussions, however it is mostly inactive and dead compared to these discussions, so I have decided to repost it here.
Although not relevant to FFPS, it is relevant to the series.
