Monster Island is a rare biome in Minecraft only found in the middle of vast oceans. All types of trees and grass grow in abundance in the biome. Regular mobs do not spawn in these biomes, but what does spawn in great quality is Kaiju mobs. Mobzillas, Rodans, Mothras, and even more mysterious and rare ones spawn here throughout the land, ignoring any spawning rules. Underground, you can find massive burial tombs and what remains of these ancient monsters, while above ground you can find the ruined signs of civilization, all annihilated by the vast Kaiju population. Unlike other biomes, all Kaiju are completely hostile towards others if spawned here.
