In order to find a slime chunk, you will first need to use the server's seed: SkyBlock [make sure it is the same] Now that we have our seed, we can use this website to locate any potential slime chunks near your island: https://www.chunkbase.com/apps/slime-finder Input the following seed and make sure it's on java edition! Once you have put that information down, write down your X and Z coordinates which can be found by pressing F3 Once you write down the location of your island, it will display hundreds of green dots which represent a slime chunk. You will have to click on the green dot in order to find the exact coordinates for it. For instance, there is a chunk at my island located at X 81044 Z 2005 In this screenshot, you can see the chunk displayed in which slimes can spawn [16x16]. In order to turn on the chunk finder you will have to press F3 + G [may vary for everyone]. Please keep in mind that slimes only spawn in a low y-level so I recommend anything below Y-40. Once you've built low enough slimes will start spawning once you place down your slime spawner! Have fun
