Lego Harry Potter Years 1-4 Walkthrough Part 27: Chamber of Secrets, Free Play
Not the part you are looking for? No problem!
Chapter 1: Floo Powder
You will need to go to the right, by the picket fence. In that corner is something that has to be dug up. You will need to shift to get Crookshanks and dig up Character: George Weasley.
Go ahead and go inside to get the Floo Powder, and put it in the fireplace to get to the next area.
You will then be in Borgin and Burges. You will notice that one chest that could swallow you up before. Go ahead and shoot it, and then go down there. You will find a big black ball, so use a dark magic character to shatter it and get the reward of a Green Crest Portion.
Climb up the ladder, and you will see a metal lock on a chest. Blast it, and then open it to release the Student in Peril.
You do what you need to do in order to leave the store. You should also use some dark magic on a box near the entrance. You will then have Character: Arthur Weasley.
When you get to the next area in the alley, you will find that bridge that has the last crest portion you are looking for. Go ahead and use dark magic to open the door, and then levitate some boards on the cart so you can get up there to claim the Blue Crest Portion.
Go on and Save and Exit.
Chapter 2: Dobby’s Plan
Go ahead and take out Dobby the first time, and then cross over. When you hit Dobby a second time, you will need to go all the way to the left, where there is a dark cabinet. Use dark magic on it, and you will have Character: Draco (Quittich).
Keep going until you reach the area where you take out Dobby the fourth time. You will find that there is a painting wrapped up like a scroll that needs to be levitated on the wall. Take the time to do that.
Go on and jump down, and use Lumos on the chest in the corner. Blast the lock and chest, and you will have the Student in Peril.
As for the portrait, go ahead and become Professor Snape and wave in front of it. This is one character that works, and one you should be using now. For some reason, not all characters are capable of producing a reaction in front of this Portrait, at least the first time that you play. This is Portrait 1/2.
You will notice that when you cross the bridge, there is another portrait that can be levitated. Snape can also wave in front of it, and this is Portrait 2/2. You will be able to pick up the Green Crest Portion here.
You will then be in the final hospital area. You will need to get into the last area to get what you need. For that, levitate the one bed on the left to get a knight up and add ‘em, and his axe will bust the lock.
In this area, there is a safe. Go ahead and become Griphook and open the safe. You will have the Red Crest Portion.
Go on go to the thing in between the coded cabinet and the safe. In all honesty, I can’t tell what this is. Use dark magic on it, and then shoot it. You will then get Character: Madame Pompfrey.
Go on and Save and Exit.
Part 3: Crabbe and Goyle
The first reward you can get is found by yanking on the chain on the left here. It requires a strong character like Hagrid, which you might have earned, but Krum Shark can do it too. You will have to levitate some parts together to form a plunger, and then ride it to bounce on and clean up the green goop on the floor. There are about six goop puddles in all, and you will be awarded the Red Crest Portion.
On the right side of the room, there are a lot of barriers that you were not able to break through last time. However, Reducto really beats them all, and you will be able to pick up Character: Vincent Crabbe.
You will then need to just do what you did to get past this area last time, and that goes for getting into Slytherin as well.
When you arrive at the Slytherin Common Room, right at the entrance will be a big black ball. Use some dark magic on it and get the Green Crest Portion.
You will also find that to the right of the fireplace is black cabinet box. Go ahead and use some dark magic on it. It will then reveal Character: Gregory Goyle.
Go to the right and back by the large window, and you will find a desk with a lock on it. Zap the lock and out of it will come Character: Ron (Slytherin Disguise).
Go ahead and Save and Exit.
Part 4: Tom Riddle’s Diary
On the left side of the bathroom stalls is a chest that only Reducto can open. Destroy it, and you will find that you have a plunger. Go ahead and ride it like last time, but you’re not after green goo. You are after some puddles of water that hang around here. Go on and pick up all five of them, and you will be awarded with the Yellow Crest Portion.
On the right side of this room is a black cabinet. Use some dark magic on it, and you will get Character: Moaning Myrtle.
After getting through this level like you normally do, go ahead and go to the locked cabinet and have Hermione open it up. There will be a key there, and this key can unlock a wall nearby that holds the Student in Peril.
There isn’t any other rewards here. The good news is that you don’t have to use the cauldron to leave. Just become the strong character and pull the chains. To do that, you will need to fix the cabinet with levitation, use the earmuffs, break the glass with the Mandrake. You will also need to levitate the arches, but it isn’t anything you haven’t done before.
The first thing that you will see when you leave this area is a safe, in sepia tones. You should be able to become Griphook and open it, and then get Character: Vocalist. You’ll notice that you can form a suit of armor with levitation, but I don’t see much of a point in that.
Keep going down the hall, and you will find a chest with a big padlock. It is in the corner to the left, and somewhat hard to see. Bust it open and get the Blue Crest Portion.
You will then have to keep on going until the point where you actually leave the level. There is a safe all the way to the right of the exit. Use Griphook to open it up and you will have Character 62/167: Professor Vector.
Go ahead and Save and Exit.
Chapter 5: Follow the Spiders
You won’t find much here in the way of rewards until you get to the lake. Use the brooms to cross over to the other side, and kill off the hornet’s nest while you are at it. After you fix the dock, you can stand out on it and shoot the big metal thing there with Reducto. There will be two frogs there, and you can jump onto one of their backs in order to ride through some green arches that make themselves as you go. Once complete, a tiny island will grow and there will be the Blue Crest Portion.
Go back to the right, where there is land. You will see a black cabinet there. With a little dark magic, it will open to reveal Character: Professor Sinistra.
When you go to defeat the spider, you will see a chest with a big silver lock on it. Blast it, and you will get Character: Lucius Malafoy.
To the left of this area is a big black ball, and you can use dark magic to free up the Yellow Crest Portion.
Go ahead and Save and Exit.
Chapter 6: The Basilisk
There aren’t any hidden treasures in the bathroom, but when you get underground, that quickly changes. For example, there are two chests wrapped up in Devil’s Snare. Use Lumos on them, and then Dark Magic. One will contain Character: Gilderoy Lockehart and the other will contain Character: Wizard (Green).
There are some areas that need to be dug up here. Hermione’s Crookshanks can take care of that. Patch 1/4 and Patch 2/4 are at the main level, but you have to get higher to get Patch 3/4. You will have to cross over to the other side by the big dragon’s head to get Patch 4/4. Once you dig up all of them, you will have the Yellow Crest Portion.
When you get to the Basilisk, there is an area that contains a metal padlock. The padlock must be broken off, and then there will be parts revealed. Levitate these to build a birdhouse, and you will have the Blue Crest Portion.
You should notice a safe in the back corner. I found that while the Basilisk was still about, I couldn’t get to the safe. Tom Marion Riddle constantly blocked me. However, after doing the things required to make the strength potion, and then hitting the basilisk, this seemed to bring Tom Riddle out, and then you can become Griphook and open the safe to get Character: Tom Riddle.
Go ahead and Save and Exit. You should also move on to Free Play at Part 28.
