DatapacksJava
Life Potato
Java data pack listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
This datapack makes Poisonous Potatoes useful for the Player. When eaten, it grants an extra heart, up to a maximum of 20 hearts.
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.
Life Potato
Poisonous Potatoes are no longer useless! With this datapack, eating a Poisonous Potato will permanently increase your max health by 1 heart (2 HP), allowing you to reach a maximum of 20 hearts.
