Planet (Jungle Adventure)

An Earth-like planet was home to a jungle. The Second Doctor, John and Gillian arrived on the planet to test the Doctor's newly invented exploration truck. They encountered a group of Daleks who were constructing metal tracks on which to travel. The Daleks fired at the truck, destroying it, but the Doctor and his grandchildren escaped by swinging on vines to the TARDIS. There, the Doctor used cables connected to the TARDIS' power supply to send a high current through the tracks, destroying the Daleks. (COMIC: Jungle Adventure)
