Planet (Doomsilk)
From Tardis Wiki, the free Doctor Who reference
While the TARDIS was drifting through space, Heather McCrimmon noticed a small white planet and asked the Tenth Doctor to pilot the TARDIS to it. They found that the planet was covered in the living silk of a large spider. Duplicates of the Doctor and Heather formed from the silk and attempted to wrap the Doctor and Heather in web. Heather and the Doctor were able to escape by covering themselves in the slime that the silk worshipped. (COMIC: Doomsilk)
