Trophy room

Go to the Leaky Cauldron after you have learned Reducto, and destroy the piece by the stairs (it will flash blue). Jump down, and you will be in a room with four areas dedicated to each year. You must collect all Gold Bricks for each level to build whatever it makes. -From: Ashley Pugh

Easy Ghost Studs

Enable the "Ghost Stud" extra option. When Nearly Headless Nick is floating and not moving, stand underneath him to keep getting Ghost Studs.

Destroying red sparkling objects

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.

Ron Weasley with red hair

Successfully complete the first two levels, then go to the wizard town through the Leaky Cauldron. Enter the last shop on the left (before the bank), buy the "Multicorfors" spell, and cast it on Ron Weasley. Although he will shake his head as if the spell has worn off, his hair will remain red.
