I'm assuming you're talking about the blue slime balls?
They can be used as tool components by crafting them into Slimy Mud and then smelting that into a Slime Crystal. They make superior handles to most materials in Tinkers Construct.
Have a problem, how do I change those blue slime balls into green slime balls? I made a Forge Lexicon, but the conversion is disabled. How do I enable it?
