Minecraft wiki entry for Slime, associated text: A slime's attack speed is twice that of other melee-combat mobs.[2] This speed is noticeable when the slime has the player cornered at a wall. Mobs like zombies and spiders attack at a rate of one hit per second, while slimes attack at a rate of two hits per second. Slimes damage all players and iron golems‌[JE only] they collide with, unlike other mobs that damage only those targets they specifically attack.
