Wooden Queen

The 'Wooden Queen' was a being created from an Androzani tree to ensure the safety of its forest.

History
When Madge Arwell was used as a lifeboat to save the trees' life force and travelled through the Time Vortex back to 1941, the Wooden Queen and King were turned into ordinary wood. (TV: The Doctor, the Widow and the Wardrobe)

Characteristics:
The Queen, like the King was mute. However, it was able to communicate by touching a person's neck and using that person's vocal chords. It presumably grew from what looked like a Christmas tree bauble, from which the Wooden King hatched like a bird from an egg. (TV: The Doctor, the Widow and the Wardrobe)
