Slimeball

The Slimeball is an item dropped by Slimes. Its only uses are crafting Magma Cream and Sticky Pistons.

0-2 slimeballs drop when a small Slime is killed. The slimeball cannot be thrown. As slimeballs come from a mob, they are a renewable resource.

Player-invented uses
Previously, some multiplayer servers used slimeballs as tokens or cash due to the Slimeballs having no crafting purpose. However, since the 1.7 update, they are used in the construction of Sticky Pistons and since the 1.0.0 update, Magma Cream, making its currency usage undesirable. Furthermore, players could simply get free slimeballs from Slimes if they were enabled in the server. And as of 1.1 using the super-flat terrain, you can now get almost unlimited slimeballs.

As a Crafting Ingredient
Slimeballs are used to craft Sticky Pistons. When combined with Blaze Powder it produces Magma Cream.
