In a brief summary: Slimes are a hopping green, cube formed mob. They come in 3 sizes: Tiny, Small, Big. The bigger they are, the more damage they deal. If you kill a big slime, smaller slimes will drop. If you kill a small slime, tinier slimes will drop. Slimes drop slime balls, which currently in this version of the game (1.6.6), they have no use. However, in the next update (1.7.3), you'll be able to make sticky pistons with them. They're a pretty rare mob as they have a low spawn rate and a unique spawn. A thing to note: Tiny slimes do no damage, and have only have half a heart of health.
