Headbands, Spawn Eggs, and Ramen: Utility Items
Village Headbands
The registry has five Genin headbands: Hidden Leaf Genin Headband, Hidden Cloud Genin Headband, Hidden Mist Genin Headband, Hidden Sand Genin Headband, and Hidden Stone Genin Headband. Wear the one matching the village you want to represent. They are cosmetic identifiers, so pick the village whose spawn egg you plan to use.
Spawn Eggs
Each village has a matching shinobi spawn egg: Hidden Leaf Shinobi Spawn Egg, Hidden Cloud Shinobi Spawn Egg, Hidden Mist Shinobi Spawn Egg, Hidden Sand Shinobi Spawn Egg, Hidden Stone Shinobi Spawn Egg. There is also Asuma Spawn Egg for the named character. Place these in a walled area if you want a controlled fight or a training dummy that fights back.
Food and Seasonal Items
Ichiraku Ramen and Christmas Ramen are the two ramen items — both restore hunger, and Christmas Ramen is the seasonal variant. Gingerbread and Advent Calendar are the other holiday entries. Chakra Paper and Clan Paper are the two paper items used for nature and clan setup, so keep a stack of each in your base chest alongside your Chakra Nature Reset and Clan Reset. Banknote Of Ryo, Bronze Ryo, and Gold Ryo round out the currency items you will accumulate from missions.
