Jellies is an addon to TerraFirmaGreg-Modern (1.20.1) which adds cute slime-like Jellies that you can ranch for materials or keep them as pets.
Jellies fall into a few categories:
Non-producing (Spring/Pyritie) - usually reserved for "collectable" jellies.
Slime Ball producing (Plant/Glowberry/Latex/Phosphorum/Herbal/Biotite) - produce slime balls that can be turned into items using recipes defined in modpacks.
Unique Production (Certus/Rock/Cheese) - produce products, but in a more unique way.
Unique Mechanics (Lava/Ice/Pentetic) - do not produce anything, but have something functionally different.
