Built by "The Duke" whom you will meet when you visit the Old Edna Townsite, as a special place for his grandson, Kienun, to play. Most days, though, it serves as a lookout for Coy Kitty, so he can take in all that goes on around the town site, keep tabs on any vittles that may come his way, as well as take in a little sunshine. If anything is amiss, Coy notifies Kienun, the townsite deputy, for a closer look (this way Coy Kitty doesn't have to leave his post in the sunshine).

Unfortunately, Kienun's Treehouse is not open to the public at the moment, but there is plenty of space on the grass for kids to play...
