And Fraggles had this way of singing songs really creepy-like, swaying this way and that in their fraggle dance. A forboding dance, if ever there were one. Jim Henson created evil things. 

I forgot, the clackling spider minions of the Skexies in Dark Crystal, also very disturbing. 

I have an episode of Fraggle Rock on tape from when I was like seven. It's about the traveling hobos who're looking for the &quot;song&quot;. Sort of like the Tinkers from Wheel of Time. :)
