The Moonbase

The Second Doctor (Patrick Troughton) tries to take Ben, Polly, and Jamie to Mars but accidentally winds up on the Moon. Jamie whacks his head, and thus our gang are embroiled in a plot to destroy the Earth through a remote weather station. The Cybermen stoop to infecting the crew through their sugar, turning them all into zombies, and then scrap that plan and just bring out their massive laser cannon. Remarkably, they are defeated by a nail polish remover and a giant phallic Gravitron (patent pending).

Steve and Andrew return to the Cyber Control Centre but soon Andrew is starting to feel ill and sees the Phantom Piper for himself! Also, lightning hands, and Steve has another botched interview with a Cyberleader.
