In the folklore of the Balkans, vampire fruits are fruits, generally pumpkins or watermelons, that take on life and gain a taste for blood. The origins of this belief are unclear, but is most widely believed among travelling people.

There are several explanations as to why fruits come to life, but the most common one is if a pumpkin is kept after Christmas, it will become a vampire. Likewise, fruits left out after dark may come to life. A spot of blood on the skin of a pumpkin or watermelon indicates that they have become a vampire.

I’ve been bouncing the idea around in my head all day about making a vampire dating sim/visual novel, where the player is a vampire hunter, each route is a “contract,” and the player gets the option to kill or spare each one of the love interests (and, of course, if you don’t score enough points during the game to properly seduce your vampire, they’ll kill you at the end as well).
