To destroy objects with red sparkles around them, you must use Dark
Magic. In order to use Dark Magic, you need to use the Polyjuice Potion
or an evil character (for example, Barty Crouch Jr., Lord Voldemort, or
Tom Riddle) in Freeplay mode. An evil characters' Wingardium Leviosa
spell is changed to the Crucio Curse and can destroy the red sparkling
objects.
