Tinsel
From Tardis Wiki, the free Doctor Who reference
Tinsel was a common Christmas decoration.
Karfelon circuitry was once described as "like tinsel at Christmas". (PROSE: The Taking of Planet 5)
Animate tinsel accompanied a Roboform Christmas tree which was placed at 48 Bucknall House on 24 December 2006. (TV: The Christmas Invasion) Capable of restraining humanoids, the tinsel captured the Master when he arrived at the flat on the following day. However, he was freed by the Third Doctor. (PROSE: The Christmas Inversion)
Donna Noble was once tied up with tinsel when she was captured by sentient snowmen and robotic Santas. (PROSE: Dr. Tenth: Christmas Surprise!)
