This castle sits near the western boundary of Marshroom Kingdom and houses the ruling Princess Pear, as well as her devoted army of Froggs. A selection of VIPs also live here, under the greatest protection the kingdom has to offer. Emerald green paint covers every inch of the exterior, and inside, the color scheme continues to an almost nauseating extent. The castle has a natural defense in the hill it sits atop, which affords the royal guard the perfect vantage point to spot would-be invaders from a mile away.
