LEGO Harry Potter Years 5-7

To get this achievement, each Weasley family member must interact with any of the Weasley boxes. It is not necessary for each variant to use the boxes, or to obtain each item. Here is the list of characters needed:

Ron
Ginny
George
Fred
Percy
Charlie
Bill
Arthur
Molly

UPDATE:

The following guide was provided by Phoenix C64:

(disclaimer: some of this stuff might not work if you haven't progressed enough in the story, i don't know for sure, i did this after completing everything else)
1) from LEAKY CAULDRON: exit through left door, go all the way down in DIAGON ALLEY and exit bottom left to KNOCKTURN ALLEY.
2) there exit top right door to enter [BORGIN & BURKES] SHOP and inside there use the teleport to hogwards (i forgot the name of the device)
3) you'll appear in the ROOM OF REQUIREMENT HALLWAY, just move downwards and you'll come to a cauldron where you can switch to the needed character. then just walk a little more down, go down the stairs and you'll appear in GREAT HALLWAY right in front of a WEASLEY BOX.
4) use the box, go back to the cauldron, rinse and repeat until you got the chievo.

You must open a Weasley box with each Weasley family member. You can use any variant of the character (and you only need to use one variant). Here's a guide I made that has the locations of all the collectibles, including the Weasley character tokens.

Once you have the token, buy them from Madam Malkin's in Diagon Alley. A good place to get this achievement is the "Outside Passageway" area (see the map in the guide above). There is a cauldron here so you can switch characters and use the nearby Weasley box.

These are where you can find the "main" versions of each character, just as an example. Use Ctrl + F to find each section in the guide.

Ron Weasley - Automatically given from the start of the game
Ginny Weasley - Love Hurts (Level 6-4)
George Weasley - Weasley's Shop (in Diagon Alley)
Fred Weasley - Weasley's Shop (in Diagon Alley)
Molly Weasley - A Not So Merry Christmas (Level 6-3)
Arthur Weasley - Kreacher Discomforts (Level 5-4)
Charlie Weasley - Outside Passageway
Percy Weasley - Wilderness Forest
Bill Weasley (Wedding) - A Not So Merry Christmas (Level 6-3)

To get the achievement, you need to use a Weasley box with every Weasley.

You don't need every variation, you just need to use the box with all the following characters

Ron, Ginny, Fred, George, Arthur, Molly, Bill, Charlie and Percy.

The easiest place is to go to the Weasley's Courtyard, there is the cauldron and box in the same location.
