Planet (The Beginning)

This topic might have a better name.

The "Unnamed" in the title is redundant.

Talk about it here.

A planet with a blue sun and air like wine was visited by the First Doctor and Susan after they left the Moon. The Doctor's TARDIS assumed the form of a giant mushroom. The Doctor had intended to go to Earth, but in his excitement, forgot all about it at the moment. (AUDIO: The Beginning)
