The Ahool is a cryptid that reportedly lives in the Java Rainforest in Indonesia. It’s name was given to it because of the sound it makes (Ah-hool!). This creature was first reported in 1925 and has since been considered a cryptid though no substantial evidence has ever been found to support the claims.
The descriptions of the creature vary from a large bat to a monkey with wings. It is however usually described as a large bat or owl with dark eyes and a tremendous wingspan of 3m (10 feet). It is said to have greyish fur, large claws that run down the wings and a loud scream which it was named after.
