The Sunscale Kobold tribe typically lives on a surface, different from your typical cave-dwelling Kobolds. Since this band of Kobolds loves to trade and travel, they need some way to protect themselves, which is why they have Wagons of holding, allowing them to even travel with a dragon inside just one Wagon!

This was a gift from my amazing showing off his Kobold tribe's best invention, the Wagon of holding. This allows for them to store many other Kobolds and items from their travels across the lands.
