Why is there slime falling from the sky in Terraria?

The Slime Rain event in Terraria occurs when certain criteria are met, including having at least one player with more than 140 maximum health and more than 8 defense, although in Expert Mode, it can happen with a lower chance before meeting these requirements. The event is signaled by the message “Slime is falling from the sky!” and continues until 150 slimes have been defeated, at which point King Slime will spawn.
