Monkey seizes the opportunity to steal the Bull Demon King’s riding animal at the Green Wave Pool. He changes himself into the Bull Demon King and rides to the Plantain Cave where he obtains the real fan (fire-extinguishing fan) by fraud. When the Bull Demon King discovers that his riding animal is missing, and reckons that it is Monkey who has stolen it, he hurries back to the Plantain Cave. At this time Monkey has already taken the fan, so the Bull Demon King changes himself into Pig and swindles back the precious fan which he then hands over to his wife.
