Working on the Goblin's Homecave area, ooutside area, and the Mines themselves which will be a multi floored Dungeon that increases in difficulty the deeper you go.

Goblin Queen has her own special sprite and is safely in her Throne room, but also segregated from the outside world. The Goblins keep her sheltered from the horrors of the outside and every day she chooses which color Berry she wishes to eat that day. The Goblins then use this decision to determine their "Gobmarket" prices and trade Berries amongst the Homecave based on this information, almost like a fantasy stock market.

Players won't have to worry about all the Gobmarket stuff as it will only be a world building thing for the Goblins.
