Mudstone

Mudstone is a mineral that can be obtained from both the Geode and the Omni Geode. Like other minerals found in geodes, it is primarily a salvage item rather than a crafting resource, but it still has several niche uses outside of collection and profit.

Mudstone can be used in tailoring and dyeing. When placed in the spool of the Sewing Machine with Cloth in the feed, it is consumed to create a clothing item. If it is used with a dyeable clothing item in the feed, it acts as a brown dye. It can also be placed in the orange dye pot at Emily and Haley's house for use in dyeing.

It also has a Fish Pond quest use. When a Bullhead or Largemouth Bass requests 1 Mudstone, completing that request increases the pond's capacity from 7 to 10. This makes Mudstone worth keeping at least once if the player is maintaining either of those fish ponds, since the capacity boost allows the pond to hold more fish and continue progressing more efficiently.

In practice, Mudstone is usually best saved until its special uses are no longer needed. Useful cases include:

• fulfilling the Fish Pond request for Bullhead or Largemouth Bass
• using it as a brown dye in the Sewing Machine
• placing it in Emily and Haley's dye pot for dyeing
• using it in tailoring with Cloth

Outside of these uses, Mudstone has the same general role as many geode minerals: it is most often found while processing geodes, and after the needed quest or tailoring applications are covered, it can be treated as a collection item or sold.
