Slimes

Slimes are alien creatures that inhabit The Far, Far Range. They are rather adorable, as many would say. Slimes are vital to the game because not only would it be false advertising if Slime Rancher didn't have slimes (for kinda obvious reasons) and also because they wouldn't be able to make plorts to sell. There are many species of slimes, each one unique and has many different features. This page will list each slime type under how much they can harm the player, ranging from peaceful to dangerous. Rare is for slimes that you have a small chance of encountering. Other is for slimes that don't fit into any category, including rare. Scrapped means they will never be implemented in the game and were cut and Upcoming means that they will come in a future update. A slime may fit into multiple categories. This includes rare slimes. This may not be entirely accurate though. This only applies to Canon slimes.
