Planet (Lizardworld)

An Earth-like planet was home to giant lizards, some of which lived in a mountainous area. When the First Doctor, John and Gillian arrived on the planet, the TARDIS was taken away by one of the lizards. They tried to follow after it, but were themselves captured by another lizard. The Doctor used his fob watch to hypnotise the lizard guarding them and they escaped, taking shelter in a nearby cave, in which they found the TARDIS. (COMIC: Lizardworld)
