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

1. Wear a Creeper Head or Happy Creeper Mask to get close safely.
2. Feed the creeper an Anti-Blast Biscuit to weaken it.
3. Feed the weakened creeper a Sweet Gunpowder Biscuit to tame it.
4. Right-click your tamed creeper with an empty hand to open its companion UI.
5. Use Shift + right-click with an empty hand to switch between follow and stay in the world.
6. Heal it directly or let it use stored fuel automatically when hurt.
