This mod adds 19 rats to your Minecraft world, along with a new rare rat structure, and a few new items.
Underneath are a few examples of the rats added to the game.
Among the new items are meatballs, a staff that can summon rats, rats deferring depending on whether you have either of the new rat totems. Along with 2 summoning blocks for boss rats, said rats don't actually do that much.. but they have a large chunk of health. You can also eat the rats, some giving effects.
Have fun with it, that's all.
