EDIT: Thanks to Mister Chambers, "Just a heads up, there's another brick that isn't listed here for 'Collect Ghost Studs'. The code is MLAA8P."
EDIT: Another note from Th3 Awesom3 One, this apparently can cause glitches to other achievements. I have not personally had an issue like that, but if he says it can happen then my experience is just one of many where it didn't. Hope this helps!
There are a total of 20 red bricks in the Single Player game. 19 of them can be unlocked and collected by entering in the various cheats (see roadmap). Red Brick 18 is the only one that can't be unlocked through entering cheats. This 18th Red Brick first shows up on your way to Year 2 Level 2 as you are making your way through Hogwarts. There is a courtyard with a fountain surrounded by four statues. Destroy the statues, and with the remains form a knight. He then comes alive and plunges the water out of the fountain, and your Red Brick container appears. Bring it to Hedwig in the upper left corner and the last Red Brick is yours!
If you happened to use a cheat to unlock your 20th Red Brick, as opposed to using the method above, you won't get your achievement until you re-collect any Red Brick again. Then the game recognizes you indeed have 20 and you will unlock it then.
If you do not want to use cheats to unlock the Red Bricks, you can use the COLLECTIBLES GUIDE to find them. If you want to find them yourself, but with a Red Brick Detector use this cheat (7AD7HE).
