Instructables member Look_I_Make_A_Hat made this soul-consuming Furby and provides instructions on how to, if you dare, create your own to unleash upon the world. You and I are compelled to do so, for we crave to obey the centifurby.
Although the creature really reminded me more of a sandworm (Bless the Maker and His water) from Dune than a centipede. That thought got me Googling a bit, leading me to this wonderfully terrifying creature.
It appears that making Furbies monstrous is an entire genre of crafting.
