Items are anything in the world of Don't Starve which can be picked up and carried around (as opposed to objects, which are stationary). Items can be found by foraging, mining, farming, fishing or killing mobs, except for a select few which are character-specific items. (Some found below) Most items have a specific function, which makes them unique; Food items restore Hunger. Clothing provides warmth, protects against damage and can boost Sanity. Other items can be used for Crafting.
