Jenglot is believed to be found in Indonesia, especially in Java. They are mostly found by native psychics after they have performed a supernatural ceremony. Jenglots are said to be found anywhere, from under the ground, on a wrecked house roof, and even in the trunk of a huge tree.
Jenglot 'keepers' feed their creature with blood, either animal blood (goat) or human blood. Those who feed the creature with human blood buy it legally from the Indonesian Red Cross. The jenglot is said to not drink the blood directly. The person places the jenglot near the blood, but the jenglot doesn't even move or touch the blood. It is said that the jenglot will get the nutrients of the blood in their own way. Some say it comes alive and consumes the blood when it is alone.
In Indonesia there has been several "exhibitions" of jenglot specimens found and showcased. Most being found on the islands of Java and Sumatra, and are held as private collections of supernatural researchers and fans. Many were found to be hoaxes, being masterful taxidermist fixings of monkeys and fish, however, not all specimens were examined, and the jenglot is an actively believed myth that many natives believe to be real. People who have caught the jenglot usually bring their creature all over Indonesia to exhibit them in order to gain some money.
