Planet (The Doctor, the Widow and the Wardrobe)

This unnamed planet was a snowy world with forests of Androzani trees. The Eleventh Doctor considered it to be the most peaceful planet he knew.

The Doctor planned to take Cyril, Lily and Madge Arwell to this planet. He used a portal disguised as a present to connect 1941 and 5345. At the same time, Harvest Rangers from Androzani Major had come to harvest the forest for fuel. The trees knew of both events and had planned for them. They grew into a spacecraft and used Madge to transport their lifeforce, allowing them to escape the harvesting. (DW: The Doctor, the Widow and the Wardrobe)
