A World with Maty Chiquito

This modification introduces players to a unique creature named Maty Chiquito. This is a neutral mob that can be either tamed or defeated in battle - in the latter case, you'll receive a special item. Use chicken nuggets for taming, and you can encounter this creature in any biome of the world.
The mod also adds several new gameplay elements: a special type of leather for creating armor, a new kind of iron (which when combined with other materials allows crafting various armor sets), as well as unique structures, bosses, a completely new biome, and many other surprises that you'll discover during gameplay.
Important note: the mod may function incorrectly when using OptiFine.
