Chronomite
From Tardis Wiki, the free Doctor Who reference
Chronomites were four-dimensional creatures who lived in the Void and in riptides in space-time. They were harmless but very itchy. The Eleventh Doctor convinced the Entity to feed on them as they would continually renew themselves. (GAME: TARDIS [+]Loading...["TARDIS (video game)"])
Rassilon referred to the Sicari as chronomites to be crushed beneath his heel. (AUDIO: Assassins [+]Loading...["Assassins (audio story)"])
