Today we present how to utilize broken mob spawning algorithm to speed up the game, to cause a behaviour known as ninja creepers or invisible creepers. Since mob spawning issues are to be resolved in Minecraft 1.13.2, fish spawning cannot be used to slow down the game, one can replace it with any other 'lag' generating mechanics, like redstone (targeting cpu), or nether portals (targeting disk and memory).

For monitoring I used carpet mod for 1.13.1, but the techniques I presented apply to any vanilla server or singleplayer world (singleplayer doesn't even have the limits on the delay as far as I know)
