Diagon Alley had changed. The colorful, glittering window displays of spellbooks, potion ingredients, and cauldrons were lost to view, hidden behind the large Ministry of Magic posters that had been pasted over them. Most of these somber purple posters carried blown-up versions of the security advice on the Ministry pamphlets that had been sent out over the summer, but others bore moving black-and-white photographs of Death Eaters known to be on the loose. Bellatrix Lestrange was sneering from the front of the nearest apothecary. A few windows were boarded up, including those of Florean Fortescue's Ice Cream Parlor. On the other hand, a number of shabby-looking stalls had sprung up along the street. The nearest one, which had been erected outside Flourish and Blotts, under a striped, stained awning, had a cardboard sign pinned to its front:
AMULETS
Effective Against Werewolves, Dementors, and Inferi!
A seedy-looking little wizard was rattling armfuls of silver symbols on chains at passersby.
"One for your little girl, madam?" he called at Mrs. Weasley as they passed, leering at Ginny. "Protect her pretty neck?"
"If I were on duty..." said Mr. Weasley, glaring angrily at the amulet seller.
The amulet seller seems like some kind of paedophile, IMO.
Set against the dull, poster-muffled shop Fronts around them, Fred and Georges windows hit the eye like a firework display. Casual passersby were looking back over their shoulders at the windows, and a few rather stunned-looking people had actually come to a halt, transfixed. The left-hand window was dazzlingly full of an assortment of goods that revolved, popped, flashed, bounced, and shrieked; Harrys eyes began to water just looking at it. The right-hand window was covered with a gigantic poster, purple like those of the Ministry, but emblazoned with flashing yellow letters:
WHY ARE YOU WORRYING ABOUT
YOU-KNOW-WHO?
YOU SHOULD BE WORRYING ABOUT
U-NO-POO--
THE CONSTIPATION SENSATION
THAT'S GRIPPING THE NATION!
Now this is freaking funny. U-No-Poo indeed.
