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.
• Tamed Creeper Features
• Follows its owner and can be told to stay
• Teleports back if it gets left behind
• Changes dimension with its owner
• Resyncs after the owner respawns
• Defends the owner from hostile mobs
• Attacks mobs the owner is fighting
• Uses a small contact blast attack instead of normal self-destruction
• Dies with a larger non-destructive final explosion
• Has increased health compared to a normal creeper
• Visual Features
• Weakened creepers show a continuous visual effect
• Tamed creepers use a custom happy green texture by default
• Tamed creepers can be recolored with dyes
• Rainbow Biscuit unlocks a smooth rainbow mode that cycles through colored creeper textures

Items

• Biscuit
• Anti-Blast Biscuit
• Sweet Gunpowder Biscuit
• Rainbow Biscuit
