Morrowind's data files contain a number of test rooms that can be accessed using the game console. The rooms include "Character Stuff Wonderland", "Clutter Warehouse - Everything Must Go!", "Draugr Test" (in BloodMoon), "ken's test hole", "Mark's Script Testing Cell" (in BloodMoon), "Mark's Vampire Test Cell", "Redoran Test", "Redoran Test 2", and "ToddTest".

Many of these rooms have self-explanatory purposes, although a few have noteworthy attractions in them. The "Clutter Warehouse - Everything Must Go!" room has two strange NPCs in it: Lord Cluttermonkey, who is an Argonian in Daedric armor who has a mace called Clutterbane, and the Used Clutter Salesman, a Bosmer dressed in exquisite clothes who has a Daedric warhammer.
