Water of Youth
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Make your pets never ages with this DataPack. You can turn entities into baby or adult form at will.
Craft the new Potion of Youth or Potion of Age and throw it to an entity in order to make it a baby again or an adult instantly.
Entities sprayed with the Potion of Youth will remain in its baby form (won't age) until a Potion of Age is used on them.
ARCHIVED: Given the addition of the Golden Dandelion this project will not receive any future updates for the time being.
