How to get all 8 slimes from your town for this achievement.
 

Elder Slime

It is located underground in the cavern layer and more often in the dungeon. It is locked in a regular chest. To unlock the chest, you will need a gold key. It is easy to spot because the chest moves like a slime. Skeletron must be defeated before the Elder Slime can spawn. It will be identified by the lifeform analyzer as an Old Shaking Chest. If you are too far away from the chest, it will despawn. Make sure to bring a key with a golden key!
 
 
 

Cool Slime

When a natural party is taking place, he arrives like any other NPC. If you use a party centre, he will not arrive.
 
 
 

Nerdy Slime

Spawns after defeating King Slime.
 
 
 

Squire Slime

Make a copper helmet and drop it to any basic slime. The slime will turn into the town slime. The Royal Gel is not intended to kill the slime.
 
 
 

Mystic Slime

A mystic frog can spawn anywhere in the jungle. Purification powder can be used to turn it into town slime. It can be killed by using the Guide To Critter Companionship and not summons. It is important to be close to a town to prevent monsters from spawning. The Lifeform Analyzer does show the mystic frog. Although it seems to spawn more frequently on the surface, it can still spawn underground.
 
 
 

Surly Slime

You can fish for this slime anywhere during a blood moon.
 
 
 

Clumsy Slime

It can be found randomly while you are flying on a balloon. It is not like other balloon slimes that you must be in the Space Layer to allow it to spawn. You can wait for one to appear on floating islands. The Clumsy Slime is able to fly away and despawn.
 
 
 

Diva Slime

Sparkle Slime Balloons from Queen Slime will make your town shimmer.
