Slimes are green cubes that move by hopping. There are 3 sizes: big, medium, and small. The small slimes will drop 1-3 Slimeballs, which can be used to make Sticky Pistons and Magma Cream. Small slimes will do no damage to the player, whereas the Big and Medium slimes will do some damage depending on the size. Their health is also dependent on the size of the slime. Slimes split when killed. The Big slime splits into about 4 Medium slimes and each Medium slime splits into 4 small slimes allowing the player to get 16-48 slimeballs on average. Slimes will only spawn between bedrock and the 39th layer of the Overworld and as there's only a 10% chance of spawning slimes in any chunk, a big area will need to be cleared to spawn any slimes. Many people find it hard to find slimes in non-flat worlds because of the lack of large, flat areas.
- Slimes are abundant in Flatworlds as it's only 4 blocks away from bedrock and very well lit up.
- Small slimes can't hurt the player.
