Minecraft But a Mob Spawns Every 10 Seconds

Minecraft, but a random mob will spawn on top of you every 10 seconds, good luck. This includes bosses and the Illusioner, but not the Giant.

All mobs have an equal chance of spawning and they should start spawning the moment you load into the game.

This datapack also works in multiplayer, everyone gets a different mob spawned on top of them.
