Rare Screens:

One of the rare screens can show up whenever opening the main menu.

Credits:

Like in the other games, the credits are on a black screen, with the text moving up, and you can skip by pressing Enter on the keyboard.

Discord Rich Presence:

The Discord Rich Presence will show some info about the game on your Discord profile, such as when you're on a certain menu or playing a certain night (and the current hour), along with showing elapsed time when playing the Endless Mode.

Though I couldn't put the game's full title due to the 32 character limit, so I had to abbreviate Five Nights at Bootleg Plush's to just FNaBP.

Other:

The game is pretty much finished now, but I need to double check for any missing things before making the beta builds for PC and Android.
