Lego Harry Potter Years 1-4 Walkthrough Part 32: Index

Go ahead and follow the ghost out of the Fountain Area to the Outside Hall, and then to the Grand Hall.

Go ahead and follow the arrow to the Other Hallway with stairs.

You will soon be in an area where you will be shooting at these (for lack of a better word) robots. This is part of the training with the Expellimerias spell.

You can get some studs here, but there aren’t many. The key is for Harry to zap five of these guys, and then switch to Ron to zap them.

You will then be in what I consider to be a difficult area. You have to hit Draco five times, but you can’t target him. You sort of have to move and hope he is in your line of fire. I found that I got killed a few times with this, but eventually you will unlock Expellimerias for Gold Brick 39.

You will also unlock Parseltongue, but it won’t reward you for it. It does come into play later.

Go on and head back to the Great Hall, and follow the ghost to the stairwell. Go back to the Dormitory hall, and take a left. You will be at the entrance to Slytherin. You will come to a door with a big snake comes out of it, so make certain that Harry, the only character you have that can speak Parseltongue is there to meet with it.

This will cause three pieces of a snake to fall out. There is a purple area to the left, and you have to levitate the tail section to that area, followed by the middle section, until you finally get the head.

The door will open, and you can go through. The Entrance to Slytherin has a lot of things to do to get studs. If you go through the door, you will have a cut scene.

You then need to leave. Just go out the way that you came until you get to the Grand Hall. You will then be in the secondary hallway, where you must get to the Potions room.

Here you will make Polyjuice potion. You will see the golden put in a corner, and you will need to find some red berries, a green apple, and a hairpiece to do it.

The red berries are located on a table with a few bottles that can be zapped. Hit them all, and you will have a plant growing in a pot. This plant has the berries, which can then be put in the pot.

The green apple is located behind the golden wall. Just use levitation to remove it, and a pixie will be holding it. Immoblize the pixie and put the apple in the cauldron.

As for the hairpiece, it is located by a student who is just standing and doing nothing. If you levitate a box near him, a big vine/tentacle thing comes out and grabs him, leaving nothing behind but his hairpiece. Go and put that in the pot.

This will automatically unlock Character: Justin Finch-Fletchley. This is the only character (besides Ron, Harry, and Hermione) that doesn’t have to be bought. If you use the Polyjuice potion, you’ll find that you can access him right away. That means that you should, because you can get a whole bunch of coins. Just read the next paragraph.

By the way, there are bottles here that, when levitated, will inflate. Bottle 1/5 is in the left corner of the room, near the window to the right of the gold wall. Bottle 2/5 is on the opposite side of the room, by the other arched window. Bottle 3/5 is on one of the lab tables. I actually never saw Bottle 4/5, but it is around to the left of the cauldron behind the big (at least in perspective) pillar. Just wait for the highlight and levitate it. As for Bottle 5/5, there is only one way to get it. If you haven’t already, use the Polyjuice to turn to Justin Finch-Fletchley. Apparently, he is a Hufflepuff boy, and the portraits only respond to Hufflepuff students. Go to the portrait on the left, and wave to it. You will get a reward of a lot of studs, including a purple stud.

Now use Justin to go to the portrait on the right side. Polyjuice Potion will be unlocked, and you will have a Gold Brick.

Oddly enough, you can’t go through the doors there. So just leave the same way you got in.

Out from the Hallway, head back to the Grand Hall. You will then be led to the Second Hallway.

You’ll note that the ghost makes a right turn here, and goes to a room that has been curtained off. In order to get through here, you need to use levitation on a broom near the top. This will polish off the three odd things here. Use it again to brush off the portrait, and you should be able to enter then.

You’ll notice something glowing behind the spiral stairway. Go and get it. It is Character: Harry (Blue Shirt).

At the top of the Spiral Staircase is a new area which I call the Before the Bathroom area. You will notice the cabinet immediately to the left. Go on and use Hermione to open it. She can then use levitation to form Character: Hermione (Cat).

There is a portrait here of a wizard taking a bath. Shake him up, and he will throw his rubber ducky at you. You can shoot the ducky. Yeah, it’s not much. When you get to the lockers, that is something. You can shoot the locker, and out will come a plunger. You may notice some red squares on the floor. If you ride the plunger, you can pick up the mess. Get all 8 squares and get a purple stud.

You will need levitation to get past the green gas spewing thing here. You can then round the corner to start a small movie. You could go up the stairs, but there isn’t much there, believe me. By the way, you might notice a section that you can shoot, and vines will spout. It ends with a purple stud. In all honesty, I have no idea how to get there. It looks like you should shoot the vase to the right and get there, but it just doesn’t seem to work that way. I think it is some game malfunction. There are a few in this game.

You will see where the arrow leads. If you want, you can go all the way to the end of the hall, and shoot down the pixies holding up pipe sections. Use levitation to get the pipe sections in place, and then have Ron’s Scabbers go in the pipe. Activating the switch in here creates this weird ship that just goes around and occasionally drops a lot of studs. That is about it, though.

Chapter 3: Crabbe and Goyle

This section will involve making polyjuice. I believe that getting all three ingredients here will end this section of the level, so you might want to focus on getting studs and rewards. You will notice that one area is very much sectioned off by metal blockades, not to be accessed until Free Play.

For example, destroying the sink results in a lot of coins.

Polyjuice needs the red berries, green apple, and hairpiece.

The red berries is located in the corner of the left side of the room. Just levitate the broom, and it will knock something red down. This is not the berries, but a red dial that has to be put on a boiler nearby. You will then need leviate the thing, and the boiler will explode, revealing the berries. You can take it and put it in the pot.

For the green apple, you have to stand on a toilet located second from the right. (It is hard to stay up on here, but once you get it, it works.) Use levitation on the red wheel above, and the lids will fly up. You then have to jump to the left onto another flying toilet lid. (Don’t fall, or you’ll die in the toxic waste that is down there.) And then jump to another toilet lid. This will cause the lid to go down to the toilet, plug the system, and explode a pipe. This will cause a section to grow, and with a little levitation, you can make a flower that will freshen up that one toilet stall. You can open this once toxic dump and get a green apple.

As for the hairpiece, Crabbe and Goyle are sleeping right there. Do a little levitation on them, and the hairpiece will fall out.

Once all ingredients are put in the pot, you will be back in Slytherin hall. It looks exactly the same as when you left it last. You can use your magic levitation on the torches for some coins.

By the way, you might notice three fish that can be levitated so they go back in the water. Fish 1/3 and 2/3 are on the left side, and 3/3 on the other side. After you put them back in, the Yellow Crest Portion will slowly drift to you in the tunnel on the left. Go and get it, and get the studs in there while you are at it.

What you want is in a corner, with some Devil’s Snare vine. Go on and use Lumos on it. You will find a treasure chest that you can levitate, which will dump out parts that you can levitate to make a snake-charming pipe. This will cause four snakes to come up from the sewer covers. They will pop up one at a time, and they have to be hit in the mouth. If you want, you can get on top so you can get the blue stud that is over each one. Each snake carries a piece of a golden suit of armor.

When all are killed, you can levitate the suits of armor pieces so it turns a huge crank and unblocks the entrance to Slytherin.

You will see in the cutscene what Draco uses to enter into Slytherin, but there are some things you can do while you are here. There are two lights above you as you enter in, 1/6 and 2/6. Lights 3/6 and 4/6 are located on the opposite wall above the windows with what looks like an aquatic view. Go to the right to find lights 5/6 and 6/6, and you will find the Blue Crest Portion.

By the way, there is a broom near the fireplace that can be levitated. It will clean out the chimney, which will cause some parts to fall out. These parts can be levitated into a portrait. You can shoot the wizard in the portrait, who will in turn shoot what looks like a pile of glasses that a student is standing on. This will be the Student in Peril.

In the one area to the right, you will find a fish in a large globe. Levitate the globe, and the fish will flap on the floor to another tank. Levitate him in that tank. A skull will float to the top, and the skull can be levitated so it hits the floor. Go on and levitate its eyes, so they are in contact with its head. You will end the level.

Time to move on to Part 11.
