The Secret Thing is the exclusive subject of several episodes especially the the first, is a cylindrical orange tube whose purpose is never revealed to the viewer-though the most likely object it contains would be a top secret document of some sort rolled into a scroll, given its shape, although it rattles when shaken, eliminating that possibility.

It appears however in every episode, hidden in a new spot.
