Slimeball

The Slimeball is an item dropped by Slimes. There are no uses for it so far. Notch confirmed that they are going to be craftable in a later beta update.[citation needed]

0-2 slime balls will be dropped when a small slime is killed. Only small slimes will drop Slimeballs on death, and larger slimes will duplicate into smaller slimes unless a sword or any other tool is used.

Some users use these as tokens or cash in multiplayer servers, since it has no use and is more realistic, since server mods don't use up inventory space. When in Single Player, some use them as how many slimes they have killed.
