The Plugstack is a 'harvestable' that was introduced during the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare.
The Plugstack are typically found in corners, hiding behind pillars and beam supports, standing on top of shelves and props, and so forth. They can be found in various places that include but are not limited to:
- The Back Area
- The Grand Hall
- The Hidden Library
- The Mansion
- The Old Mansion
- The Supermarket
- The Theatre
In appearance, the Plugstack appears to be a simple device made out of what appears to be light-purple and blue stones. It possesses two light-blue eyes and a square-shaped nose, as well as two stiff legs and other ornamentations that can be seen at the top and bottom of its body.
The Plugstack does not have any usages in-game that will benefit the players, other than to be sold to a selling vendor at a selling price of 8,800 gold.
- Before the Second Riddle was deciphered, some players used the name 'Plugstack' in an attempt to crack the code of the second riddle in the zone, Inside.
