A Bao A Qu is a erudite creature made by malay witchcraft in 1937 and is said to have several tentacles and it's surface similar to that of a peach.
It begins as an invisible benign entity which waits at the bottom of a pilgrim tower and follows the pilgrim very closely behind.
As the person progresses up the tower stairs, the A Bao A Qu gains more strength and definition which draws life energy from the unsuspecting climber. This leads the A Bao A Qu to change colours like a chameleon until it finishes with a iridescent blue glow from the victim.
It is said that this creature only follows the perfect victim, so this explains why so many have attempted the pilgrim tower walk and had no A Bao A Qu success.
