The long and path-full desert.

After traveling through Mount Rugged, Mario and Friends end up in Dry Dry Desert, a maze of sand, rocks and... more sand. Many a things hide the rooms of this area, it might be a item or badge, or a completely special area. Luckily there is a pathway to the Outpost right in the center of the desert just incase you get lost.

Also, the famous explorer Kolorado is here in the desert looking for historical artifacts with his crew, maybe take a note of that for later.
