(136/6R: The Caves of Androzani)
Twin planet of Androzani Major. It featured an intricate network of caves, where spectrox-producing giant bats lived. The Fifth Doctor and Peri became involved in a conflict over spectrox between Sharaz Jek and General Chellak on Androzani Minor. When the planet moved closer to Androzani Major, mud bursts rose from Androzani Minor's core (6R).
