(which broke in the bottom of his trunk), a brilliant blue eye belonging to Aberforth (which Harry mistakes for Albus' eye), appears and he sends Dobby, who arrives to help Harry escape from Malfoy Manor to Shell Cottage. Prank objects Weasleys' Wizard Wheezes Prank objects from Weasleys' Wizard Wheezes are made and designed by the owners of the shop, Fred and George, who test their new creations on themselves and other Hogwarts students. Weasley's Wild-fire Whiz-Bangs are enchanted fireworks that have overly spectacular and remarkable effects. In the books, they are engineered to not generate any amounts of heat, light, or noise that could be harmful. In the film of Order of the Phoenix, however, the fireworks create a large fiery dragon that attacks Umbridge, burning her and leaving her covered in soot.
