Petrified Slime is a rare artifact that players can find by breaking open geodes or omni geodes at the Blacksmith, or by fishing up treasure chests. It resembles a small, solidified blob of slime and can be donated to the local museum to contribute to the collection, which rewards players as they complete exhibits. Additionally, it can be sold for a modest amount of gold, but its primary value lies in its contribution to museum completion and the lore it adds to the world's history.
