Happy Creeper

Short summary:

Turn creepers into survival companions by weakening, taming, healing, recoloring, and fighting alongside them.

Overview

Happy Creeper is a NeoForge mod for Minecraft 1.21.1 that gives creepers a full companion gameplay loop.

Instead of only running from them, you can approach them safely with a creeper head, weaken them with a special biscuit, tame them, and keep them with you as a combat companion.

This mod is built around survival-friendly mechanics rather than creative-only gimmicks.

How It Works

Wear a Creeper Head to get close safely.
Feed the creeper an Anti-Blast Biscuit to weaken it.
Feed the weakened creeper a Sweet Gunpowder Biscuit to tame it.
Right-click your tamed creeper with an empty hand to switch between follow and stay.
Heal it with Gunpowder or another Sweet Gunpowder Biscuit.
