Zubat

Zubats are bat-like creatures that usually form colonies in perpetually dark places and do not like to be bothered. They also use ultrasonic waves to identify and approach targets of attack. In "Clefairy and the Moon Stone," while searching for a short cut to Cerulean City through the dark and eerie caves of Mt. Moon, our band of heroes rescue a researcher named Seymour who is being attacked by a vast number of Zubat.
