There are 5 possible minifigs in this Harry Potter Lego Slytherin. First you have Draco Malfoy, then Crabbe & Goyle -- all in Harry Potter Lego Slytherin robes with black capes. But if you turn the heads of Crabbe & Goyle you see the faces of Harry and Ron! It's a nice idea if you can ignore that the alternate faces peek out on the backs of their necks. Harry Potter Lego Slytherin House is themed in Hogwarts dungeon colours of grey and black with a dash of green. There are two main aspects in this set -- a potion section which I assume represents the Polyjuice potion so that one can have Harry & Ron transform into the two members of Slytherin and find out what Malfoy knows about the Chamber of Secrets. The other aspect is a the actual room, which (as pictured on the back of the box) can fit on top of the Troll on the Loose bathroom set. There are some great suggestions for alternate builds of the set on the back of the box as well as a picture of how all the sets in the Harry Potter theme can fit together. For the price this set has some nice minifigs, semi-transparent pieces, and 2 black snakes. This Harry Potter Lego is set number 4735 with 90 pieces.
