Vampire pumpkins and watermelons

Vampire pumpkins and watermelons are a folk legend from the Balkans, in southeastern Europe, described by ethnologist Tatomir Vukanović. The story is associated with the Romani people of the region, from whom much of traditional vampire folklore originated.

The story was popularized by Terry Pratchett's 1998 book Carpe Jugulum, a comic fantasy novel making extensive use of vampire legends. Pratchett has stated that he did not invent the vampire watermelon story himself. It is found in several other works: Jan Perkowski's 1976 book reprinted Vukanović's account, the webcomic Digger incorporates a field of vampire squash (most of which resemble butternut squashes in appearance),
