Background

In Minecraft Java Edition 1.16, 1.17, 1.18, 1.19 and 1.20, the entity value for a slime is slime. The slime entity has a unique set of data tags that can be used in Minecraft commands such as: /summon and /data.

What are NBT tags (formerly called Data Tags)?

NBT tags allow you to set certain properties of an entity (such as slime). The NBT tag is always surrounded in {} such as {Size:3}. If there is more than one NBT tag used in a game command, the NBT tags are separated by a comma such as {Size:3, CustomName:"\"Bouncer\""}.

List of NBT Tags

Here is a list of the NBT tags that you can use for slime in Minecraft Java Edition (PC/Mac) 1.16, 1.17, 1.18, 1.19 and 1.20:

NBT Tag Value (Description)
Size

number (It represents the size of the slime. The higher the number, the larger the slime. If you enter a number too high, your game will glitch and freeze!!)

0 (Baby slime)
1 (Medium slime)
3 (Large slime)
100 (Giant slime)

Example
{Size:3}

TIP: If you have summoned a slime that is too large and your game glitches, type the following /kill command to kill all slimes in your world:

/kill @e[type=slime]

This will give you back control!! Though you may need to enter this command a few times as the slimes get smaller and smaller.

NBT Tag Examples

To summon a baby slime:

/summon slime ~ ~ ~ {Size:0}

To summon a medium slime:

/summon slime ~ ~ ~ {Size:1}

To summon a large slime:

/summon slime ~ ~ ~ {Size:3}

To summon a giant slime:

/summon slime ~ ~ ~ {Size:100}

To summon a large slime that is named Bouncer:

/summon slime ~ ~ ~ {Size:3, CustomName:"\"Bouncer\""}

Target Selectors

Before we finish discussing data tags, let's quickly explore how to use the @e target selector. The @e target selector allows you to target entities in your commands. If you use the type=slime value, you can target slimes:

@e[type=slime]

Target Selector Examples

To turn the nearest slime into a baby slime:

/data merge entity @e[type=slime,limit=1,sort=nearest] {Size:0}

To kill all slimes:

/kill @e[type=slime]
