Smyslov 3

Smyslov 3 was a planet and home to the friendliest locals in the galaxy, according to the Doctor.

It was supposed to be warm and sunny, though when the Doctor arrived it was overcast and cloudy.

History
The Doctor and Amy arrived on Smyslov to be greeted by a group of angry, horse-faced locals and an indiviual, Tanik. Tanki accused the Doctor of sabotaging his missiles and then leaving a short while ago. The Doctor and Amy left the planet before they were attacked but noted they would have to return later to sabotage the missiles. (WC: Wish You Were Here)
