SpawnMob lets you spawn mobs! But wait that's not all! SpawnMob has many features such as: Mob kits, tamed animal spawning (ocelots, horses, wolves), baby mob spawning, killing mobs, advanced horse spawning, mob spawning to custom coordinates, mob spawning onto a players location, spawn mobs riding mobs (Spider Jockeys), making mobs ride players, making players ride mobs, making players ride players, and changing what mob spawners are set to spawn. Even more features are coming soon!
