The smiling Jack-o-lantern & skull/crossbones are from one of those pumpkin carving books. The Tinkerbell I did from a printout from the Internet and then punched holes and cut stars for the sparkles. The small jack-o-lantern is one that my son made.
Here is a close up of the Tinkerbell design.

The Minnie was from a pumpkin carving design book. The Pikachu & Linus were things I got off the Internet. The pumpkin in the middle is a design from my son and the pigtail pumpkin (on the right) was made with help of my daughter (it turned out really cute).

Closeup of pigtail pumpkin. See the pigtails sticking out of the side? I used the smile that I cut out of this and another pumpkin as the pigtails then carved bows at the base of each pigtail.
