In the new level, which was that FNAF looking building you'll need to bust open a boarded-up door with an attack. Then you go in there's a scripted scene, which you probably spam E to skip but unsure. Get bathroom fucked. Then you play a mini-game that's like Plinko and try to get 4,000 points. It's quite easy if you play it "press E" and then again "press multiple E" to release balls. The best way I've done it is, press E 3-5 times as soon as you play and try to get a ball in the green outlined whole then you press E to purple outline holes which are the windows of the ranch in the mini-game.
There are scenes if you rest instead of playing, but you can revisit once gaining the key by getting 4,000 points. When you get out of the room you'll see a futa pony jerking against a wall. You can sit next to them and reveal a scene involving unshaven/smelly butthole. You'll get a scene afterward if you're brave enough to see.
