I found these pictures of original puppets of Lock and that kid who’s screaming when the snake eats his Christmas tree.  And also a random brain and what is perhaps one of Oogie’s bugs?
I LOVE seeing the puppets outside of the movie (even though Lock’s eyebrows and right foot have seen better days).  I find this extra-rad because we don’t get to see Lock, Shock or Barrel next to any of the humans in the film, and this just really brings home how freaky and not human Lock is (and therefore his cohorts as well).
