When killed, a Big slime splits into about 4 Medium slimes, and each Medium slime splits into 4 small slimes. This allows a player to get 16-48 slimeballs on average for each Big Slime. Slimes will only spawn between bedrock and the 16th layer of the Overworld. There is only a 10% chance of spawning slimes in any game chunk. This makes slimes one of the rarest mobs in the game. They can spawn in well lit areas, so it is best to light a slime farm well to decrease the chance of other mobs spawning there.
Many players choose to make Slime Farms to find slimes, as it is very difficult to find Slimes naturally in caves. First, the location of a slime chunk must be found. The location can best be found through a third party application, where the world seed may be entered and the application can provide the coordinates of a slime chunk. The most popular Slime Finder application is at extension.ws/minecraft/slimes.html. There are also many applications for Android and Apple devices.
After the slime chunk has been located, begin to clear out at least the 16 x 16 block area of the chunk, 3 blocks high, between bedrock and the 16th layer. Be sure to light the area well--glowstone and Jack-o-Lanterns are recommended, as slimes can spawn on top of them (though not on top of torches). After the area has been cleared, wait approximately 24 blocks away for at least 10-20 minutes to allow the Slimes to spawn.
- Slimes are abundant in Superflat Worlds as its only 4 blocks away from bedrock and very well lit up.
- Small slimes won't hurt the player, but push him/her instead.
- Small Slimes are rather relatively easy to kill.
