Christmas Trees

Well first there was The Christmas Invasion ( the first episode with David Tennent ) there was a Christmas tree controlled by the Roboforms ( Santas ). In The Doctor the window and the wardrobe there were trees that made themselves in a way grow the royal family.

I know. But it makes no sense how the plane survived in the Time Vortex. How did Madge work out how to drive the Androzani Harvester seeing how it has nothing to do with planes. The Harvest Rangers are so cool.

The wood aliens are a bit rubbish. All in all it was okay. But I love how Amy and Rory have a blue house.
