I'm still working on a vid of my entire haunt, but here's a couple of featurettes.
First is my Madame Leota:

...And my Skeleton Quartet, The Crypt Kickers
(There's 3 songs here. It starts with Spooky Scary Skeletons, Grim Grinning Ghosts starts at 2 min, and The Monster Mash is around 3:55, in case you want to skip around):

Two are 3-axis skulls (thanks HalloweenBob!), two with jaws only.
