How do I install Calypso's Mobs?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Calypso's Mobs work with?

The listing gives Minecraft 1.20.1, 1.21, 1.21.1. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

Calypso's Mobs

🧪 A small mod with potential to grow

We’re learning creature AI by developing this mod.
At this moment, it features just one mob—a fiery little helper you’ll definitely want to meet.

Required Dependencies: GeckoLib | Kotlin for Forge | SmartBrainLib

🔥 Furnace Sprite

Summon Furnace Sprite

A cute, animated sprite disguised as a furnace.
It smelts nearby items automatically—no fuel required.

🛠️ Crafting

You can craft it with either of these recipes:

Crafting A Crafting B

⚙️ How It Works

Furnace Sprite picks up item

Picks up smeltable items on the ground
Smelts them automatically
Spits out the results

Furnace Sprite burns faster and faster

Heats up over time for faster smelting
Cools down when idle

🌙 Day & Night Behavior

Furnace Sprite falls asleep

At night, it falls asleep if idle
Disguises itself as a regular furnace

Furnace Sprite wakes up

Holding a smeltable item nearby will wake it up!
Or… you could just give it a gentle tap

🧪 More to Come…

This mod began as a small project to help us learn creature AI.
As we grow, we’ll use what we’ve learned to create even more exciting and creative mods in the future.
