Mobsi Crops Mod (Spawning Mob from Crop)
Mobsi Crops Mod adds a new type of mob farm to the game. It adds a crop for each mob in Minecraft. It also automatically creates a seed for all the mobs added by the other mods in your imodsi folder. A crop spawns a mob a bit like a mob spawner and restart to grow from 0. So you can build a big mob farm with the seeds of all the mobs you would like gain their loots, to replace the old mob spawner.
