This mod gives the following slimes a configurable chance to spawn in the sewer:

• Green Slime
• Frost Jelly
• Red Sludge
• Purple Sludge
• Yellow Slime
• Black Slime
• Copper Slime
• Iron Slime
• Tiger Slime
• Aqua Slime
• Prismatic Slime
• Big Green Slime
• Big Blue Slime
• Big Red Slime
• Big Purple Slime
  

Each slime is given a weight in the config that determines the chance a spawned slime will be of that type. Default weights are loosely based on in-game rarity and difficulty.

By default there is a 20% chance a slime will be a big slime, and 10% chance a small slime will be special.

By default 1-3 slime will spawn per day (maybe less if they would spawn on the same tile), and the total number of slimes in the sewer will not exceed 10.

All of these variables can be adjusted in the config.

Slimes will spawn in one of the rectangle areas specified in the config, and will not enter the protected area surrounding Krobus.


Notes

The Aqua Slime is technically in the vanilla game, but will only spawn without a mod like this on Skull Cavern level 9,999,779, which is probably not so easy to reach before 2 AM (without cheating).
