Have you ever felt that your Minecraft monsters lacked variety? Randomized textures not enough? Well, we have the solution! Introducing: the Special Mobs mod!
In short, this mod introduces variants to your default Minecraft mods, such as creepers with fiery explosions, skeletons that shoot poisoned arrows, and zombies that leap at you. Not only that, but it allows you adjust all vanilla spawn rates and even make jockeys more common!
Each mob added by this mod has an adjustable rate that affects how common it is, from never appearing to being the only mob that ever appears!
