Revolt of the Mobs Mod

Revolt of the Mobs is a Forge mod that adds nine fierce new mobs to Minecraft – each with their own unique theme. With 3 tires of 3 different mobs each with their own difficulty. The mod features mobs based off some of the original Minecraft creatures, such as cows and horses. The CowPG, the first tier of cow mob, is equipped with an RPG, allowing it to shoot you from afar. The second tier of cow mob is the MOO-nster Tank, which features a cow riding a tank. The final tier of cow mob is the Mecha-MOO, a mech that the cow rides. Similarly, the horse-type mobs feature three tiers, from the weaker HorsePG to the powerful Horse Knight.  There are also rabbit mobs.
