Floor 4

The fourth puzzle for the game, "Floor 1" on ROBLOX.

Appearance
Floor four appears to be a wasteland, full of run-down castle-like towers and dead trees. The area is very barren and mountainous, setting the mood of a post-apocalyptic setting. Behind the spawn area is a beach with what appears to be water, along with what appears to be barbed wire fences. There are a few living trees, yet they are small. The castle towers appear as if they are collapsing, with holes on the sides and their foundation breaking off into the ground. On top of many of these castles are banners with these colors respectively: Purple, Pink, Purple. To the northwest appears to be castle walls, along with a cave which enters deep into the mountain, with royal blue crystals. To the east are huts with the same banners and thatch roofs. There is also a portion of this area fenced in that contains exactly 25 grass blades.

Clues
On the hut closest to the fenced area contains the equation "999x999(10+2)" which if solved equals 11,976,012.

The levers on the castle towers and the back of the cave appear to do nothing, which they may be red herrings similar to the previous floors.

The lightning strikes and thunder noises are on a loop, which may be a clue, but it could also be a red herring or just lazy scripting.

A group of 5 players waited a hour in the floor and 1x1x1x1 spawned and left after 5-10 seconds of him spawning, it is unknown to where he spawns, but he does not spawn at spawn. They believe the answer has something to do with him.

Walkthrough
There are currently no known solutions to get into floor 5.

Trivia
There once was a player by the username of 'iambettur' who stayed in floor 4 for approximately 4 hours in game and has not seen 1x1x1x1. 1x1x1x1 did appear in the server she was in about 6 or more times. She recorded all of the times he (1x1x1x1) was in the server but the recordings she made are not uploaded to any platform yet.
 * Oddly enough, the ability to purchase admin used to be on this floor.
 * The ocean behind the spawn has small areas of actual water, most of it you can fall through.
 * The river in the cave is also affected, as you can fall into the void. (Not to be confused with 'The Void,' the area 1x1x1x1 sends you)
 * About the spawning of 1x1x1x1, he apparently teleports, he was caught by a player standing in place then teleporting, while appearing near a portal checked by another player, which describes him as being able to teleport between portals.
