The Cloud Tunnel, again, is a popular destination in Worlds, but it is far from the strangest.
You enter a literal cloud tunnel to begin with, which leads you to a symmetric double staircase with a wooden structure in between. A dragon adorns the entrance. Once you proceed through the door at the top of the stairs, you enter a room that is mirrored halfway in the center.
Note: those with epilepsy should not enter this room!
