The Dept. Store Spook (or Department Store Spook) is a boss fought in EarthBound.
Allied with Geldegarde Monotoli, the Spook kidnaps Paula by ambushing the party as they try to leave Fourside's Department Store. It then retreats to the manager's office of the department store and taunts Ness and Jeff into confronting him there. Its presence in the store causes a blackout, and the civilian population is replaced by monsters.
In the Dept. Store Spook's pre-battle monologue it nearly states that Ness and Jeff will burn in Hell, but instead goes on to say that they will instead go to Heaven. The enemy's entire moveset are PSI moves. Its most common attack is Freeze α, but it also knows Fire α, Lifeup α, Brainshock α, and Magnet Omega. Its in-battle theme is Battle Against an Unsettling Opponent, as opposed to all succeeding Mooks using Battle Against A Machine.
Once he is defeated, he reveals that Paula is being held in the Monotoli Building, confident that his master, Giygas, will avenge his death. His death turns the lights back on in the department store, and the party can buy items once again.
