Ahool is an onomatopoetic appellation for a cryptid of Java and other islands in the Indonesian archipelago, frequently described as having the characteristics of a large bat with simian features, drawing some comparison with the Batsquatch of the Pacific Northwest. Cryptozoologists Ivan T. Sanderson and Bernard Heuvelmans credit the first Western report of the creature to Ernest Bartels, who had been climbing Mount Salak in West Java, Indonesia when he sighted the creature in 1925.
