The Hidden Gem is Cobbled Arch's inn, positioned at the outskirts of the village next to the mouth of a cave; it runs rather deep, and has many ores and gems in it as it connects to the village's mines, and guests are allowed to go down there while accompanied by an escort so they can experience the cave system's beauty. (It connects to Glowbug Cave in some places, but that hasn't been discovered yet.)

Dust and Bumblebee staff the inn, chatting with Vana and Veggie after a kind-of-long workday, manning the oven and pouring drinks to ensure there's a steady flow of juice and warm bread for their patrons to enjoy. Christmas helps tidy up in one of the rooms, and The Hidden Gem's current guests- Arowana, Omen, and Racer- have gone out back to wait him out. They hang around in the shade at the cave's mouth, swapping tales of their travels and subtly daring each other to venture into the dark, spooky tunnels.
(ignore the smoke from the oven they have a chimney)
