Pink planet (The Doctor and the Nurse)

The TARDIS makes a visit to the pink planet. (COMIC: The Doctor and the Nurse)

The Eleventh Doctor briefly visited a pink planet while attempting to get back to London, 1814 with Rory Williams, to retrieve Amy Pond.

This planet had two moons, a pink sky, and trees with pink leaves, upon a pink ground. It had at least one species of bird, which had two wings each, two eyes and many anthropod-like legs dangling below.

The Doctor quickly realised this was not London on 17 October 1814, and once again departed. (COMIC: The Doctor and the Nurse)
