The Wooden King
The Wooden King was a being created from an Androzani Tree. It grew from what looked like a Christmas bauble which Cyril Arwell had grabbed. Cyril followed the creature back to a copse of trees that had grown into a tower. When Madge Arwell was used as a lifeboat to save the trees' life force and travelled into the vortex, back to 1941, the Wooden King, with its Queen turned to ordinary wood. (DW: The Doctor, the Widow and the Wardrobe.)
characteristics:
The King, like the Queen was mute, and used others such as Madge Arwell for speech. It appeared to be grown from a tree which grew "Christmas tree ornaments", from which he hatched like a bird from an egg. (DW:The Doctor, the Widow and the Wardrobe.)
