Long Wapper is a giant from Antwerp folklore.
Lange Wapper is often depicted tall and thin. In comics and cartoons, his beardless chin is often highly accentuated.
The tormentor appears 'at night and haunts drunks. At first as a small man, but he can make himself bigger and bigger, until he rises above the houses. When the drunk comes home, panting and sweating, Wapper looks in through the window.
Sometimes he disguises himself as a small child to drink mother's milk. When a mother takes this child to nurse and puts it in a cot, Long Wapper makes himself grow so big that he no longer fits in the room.
