Jelly Deluge

"Strange jellyfish are pouring out of the sky!"

The Jelly Deluge is a pre-Hardmode event in Space that has a random chance of occurring each night, after the Eye of Cthulhu has been defeated, but can also be summoned with a Distress Jelly.

Trivia

 * Moon jellies are a real species of jellyfish, but don't resemble the enemies found in the event.
