This was Fred and George Weasley's favorite shop, of course-and Filch's least favorite.
Zonko's is another High Street shop, a purveyor of Dungbombs, Stink Pellets, Belch Powder, Hiccup Sweets, Whizzing Worms, Frog Spawn Soap, Nose-Biting Teacups, and Fanged Frisbees.
Once a thriving concern, popular among Hogwarts students, it seems that Zonko's business began to decline when Fred and George opened up their own joke shop.
In March 1997, Fred and George actually went to Hogsmeade because they were thinking of purchasing Zonko's and opening a Hogsmeade branch of Weasleys' Wizard Wheezes. They decided against it at the time because, with incidences involving Death Eaters and curses occurring in Hogsmeade, Hogwarts students were not allowed to visit the village on weekends.
Fred at the culmination of the Second War, and therefore before such restrictions had been lifted, and so there was certainly no attempt made at a takeover during his lifetime. Wealseys' Wizard Wheezes soon re-established itself as a major player in the subsequent peacetime, but whether they reactivated their idea and took over the shop is unknown.
