Tori’s Passive Mob Origins is an add-on for the Origins mod in Minecraft which lets players begin the game as my take on a mix of passive mobs and their real life counter parts. Instead of always starting as the default origins, you could choose an origin based on animals you pass during nearly every minecraft playthrough. Each origin is designed to reflect the natural traits of that mob, giving abilities and small challenges that match how that creature would live and interact with the world.
there are currently few origins however I plan to add one for nearly every mob in the game.
keep in mind this is a beta so there will likely be bugs
