Object
Yeti Control Unit
A fist-sized, luminous silver globe that serves as the control mechanism for the Yeti. Originally discovered by Jamie McCrimmon in cave rubble after the companions buried a Yeti, it later rolls free from the monastery gate following a Yeti's collapse. The unit moves independently, evading monks and drawing attention from the Doctor and companions. It is confirmed to regulate Yeti movements and trigger their deaths, playing a pivotal role in the unfolding threats at the monastery. Thomni also implants a similar sphere into a captured Yeti's chest cavity, transforming the creature into a weapon. The device locks into place inside the creature, its implantation unnoticed by Victoria as she enters the meeting room.
