Slimes spawn rarely and they do so deep underground in places that are difficult to reach. Combine a relatively low spawn rate with the fact that they’ll only spawn if you hold your nose just right and you’re in for a frustrating time if you want to make a sticky piston. This tool generates a map that shows you where slimes are likely to spawn. You still have to find them yourself of course, so it’s not technically a cheat, it’s more a hint. A very strong hint.
