Seasonal Let's Do
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
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.
Seasonal Let's Do is a mod that brings seamless compatibility between Let's Do mods and popular seasonal systems like Serene Seasons, Fabric Seasons, and Forge Seasons.
