Ay-koh oo-tye

Ay-koh oo-tye (Extfurb, lit. "advanced electronics") is a special kind of circuitry that allows the FurbCom Furbies to experience sentience, self-awareness and emotion.

This effect has been noticed in the integrated circuits of most inhabitants of Union of Furbish Communists, with the altered chips of the 1998 Furbies being jokingly referred to as "SPC81Ä" and "TI50C04" (compare to "SPC81A" and "TSP50C04") by Kah-Dah who was among the first to express interest in it.
