If you were looking for the "code" structure for a feature like this in Lua (the language Roblox uses), it would follow this flow:

: Identifying the RemoteEvent or RemoteFunction used by MeepCity to handle furniture placement or avatar updates.

: Instantly clones and places thousands of high-poly items in a player's estate to stress-test the local instance's rendering engine.

: Using a task.spawn or while loop to fire those events faster than the game’s standard UI allows.

: Sets all players in the vicinity to 0.1x or 10x their normal size.
