Translation: eye eye (i.e. many eyed) muraji (a hereditary title used in ancient Japan)
Appearance: If not properly taken care of, shōji—the paper sliding doors and windows found in Japanese houses—can be easily damaged and riddled with holes. When shōji have gone too long without repair, ghostly eyes begin to pop out of the holes, watching all that goes on inside of the house.
Behavior: Mokumokuren are harmless, but incredibly creepy. Their true danger lies in who their companions might be. Mokumokuren often work in concert with other tsukumogami, and are usually a sign of a greater infestation of yōkai.
