Profile - Slime

Slimes are one of the most difficult mobs to find as they currently have no mob spawner set in the game and only spawn at levels close to Bedrock. Slimes are found only in the lowest forty layers of the map, and only in certain areas.

Slimes spawn in three sizes;
Tiny – 0.6 block cube
Small – 1.2 block cube
Big – 2.5 block cube

Fun fact – Tiny Slimes cannot harm the player as their attack strength is zero.
