The MadPea Main Store at the Green Mire Swamp sells gachas and props from their games and hunts. It also has a mystery to be solved (taken from the write-up in the destination guide):
Ten years ago, Tony Lamil and Skip Dares went missing at the Green Mire swamp. A reward is being offered for any information leading to the location and/or safe return of the boys. Join the quest and explore this sim for free goodies and more.
I found the landscaping to be very well done and very spooky, as are the strange lights coming from the landing area near the destroyed helicopter which I show below. Highly recommended for a visit.
All images were taken with the green sky and water Windlight settings that were already set here.
