Lego Harry Potter Years 1-4 Walkthrough Part 31: Bonus Levels

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

Time to head over to Gringott’s Bank at the end of the street. Levitate some gears into place, and you should take on the Bonus Levels.

All of these require levitating some gears into place for the doors, and then using Griphook to open the safe.

Bonus Level 1

You should be able to get most of these studs by driving around in a car and gathering them up along the way.

You can get a lot in the corner. You will have to push a soccer ball into a goal, and this will cause some platforms to come down, and you can then get the studs.

You can use the one platform to get up higher, and there is a crane that is somewhat difficult to get to the top of. It is worth it for the purple stud at the end though.

There is a also a park in the middle here. It has four benches, and you should be able to jump on them and have someone else levitate you until you are at the top.

When you do get all 100,000, a door at the church will open. Go on and get in and get a Gold Brick.

Bonus Level 2

This level is all about pushing buttons. Let’s just say that they are numbered 1-5. You will start by having Harry stand on the button that is to the right, or Number 5. Ron will automatically move into place, and stop. Have them then push number 4. He will then move into place and stop. Then push Button number 3, and he will jump to the nearest green area. Then push button number 2, and then button number 1.

Now that he has joined you, have him take out Scabbers and let the rate crawl through the tube. The button he pushes will open a door to the next area. There are some high level studs here if you want to take some risks and jumps.

Otherwise, you can then go to the two buttons at the end here, and stand on them. A platform will descend, and you can use it to get to a Gold Brick.

Bonus Level 3

This level involves Harry and Ron. You will need to get ingredients for a cauldron. You can find the thorn on some flowers in the right corner, so get them. As for the tooth, it is on a high tower in the corner. You will need to stand on a bench, and then have the other character levitate you to get it. As for the arm, you just have to jump out in order to walk out in the midst of the lower floor to get that.

Once all the ingredients are together, go ahead and drink of it, and then pull on the chain. You will then need to use the lowered platform to get in the wardrobe, and then go and grab the mandrake. Use it to bust the glass by the button, put the mandrake in the pot behind the now shattered glass, and then have Harry and Ron stand on these buttons.

You will notice the lava level begins to rise. If you want to, you can go around the corners and grab the studs. There is much danger of falling.

Otherwise, it is all about using levitation to move the first platform to the purple brick. Jump on that platform, and then levitate the second platform into place. Jump on the second platform, and move the third into place. You can now get a Gold Brick.

Bonus Level 4

Ron and Hermione will be the stars of this level. Go ahead and release Crookshanks or Scabbers to go through the glass tunnel, and this will lower a platform. You will then need to use Lumos to eliminate the Devil’s Snare in your way.

You will notice that you are in the water, and there is a cauldron. You will find that the thorn and tooth are right there, but no skeletal arm. You will need to go to the wardrobe and get some earmuffs. Walk up to the mandrake and pick him up. Go through the glass door all the way on the right. You can put the mandrake in the bucket.

Have Hermione open the locked cabinet here. The doors will open, and you can get the skeletal arm and put it in the cauldron.

Go ahead and drink from the cauldron and walk all the way over the right. You will barely see it, but there is a chain to pull. Get up high and knock the ball down. You will notice that the ball can be rolled, and there is one area in this shallow pool that is a tad bit deeper. Go ahead and roll the ball so it is in one of these areas.

You should then go to the first set of Devil’s Snare that you see. Use Lumos, and there will be a ball you can free. Knock the ball into the water. Put it in the other one of the depressions here.

Go back to the wardrobe and turn the red crank. The water will rise, and the weight of these balls will cause them to weigh down some levers that will open the door. Enter in and get a Gold Brick.

Bonus Level 5

This level has both Ron and Hagrid. What you need to do is clear the Devil’s Snare out of the way so Ron’s Scabbers can crawl through the tube. When Scabbers crosses the green button on this side, another character will automatically hit another one, which will cause a bridge to come down.

There is a chain that Hagrid can pull here. It will be necessary to send Scabbers again through a tunnel. He will hit a button and lower a platform.

In this third area, there is the gold brick, but the entrance to the tube to get it is blocked off with a layer of glass. There is a way around this.

You will note the cauldron that needs a hairpiece, apple, and berries. The hairpiece is right by it, and the apple is in the next section over. The berries are on the next section over, but you will need to blast the trees and plants to get to them.

When you have the polyjuice potion, you will need to change into a character that can get past the door all the way on the left. I would select Dobby, as he seems to be able to open any door.

Go ahead and get earmuffed in the wardrobe, and grab the mandrake and walk him over to the tube. You will then free up the glass cover, and Scabbers the rat can grab a Gold Brick.

Bonus Level 6

You’ll start out here as Ron and Professor Dumbledore. The first thing you have to do here is turn the red crank on the left. A platform will come down, and you will have to use Lumos on the Devil’s Snare in the way.

Use the Floo Powder to take you to another area, and turn the red crank there. The other character will join you. Go ahead and get Scabbers to go through that tube. When he hits the button on the other side, I assume the other character hit it too, for a doorway opens.

Go ahead and turn the red crank. The gate will open, and you will see a cauldron there that needs an apple, red berries, and a hairpiece. The berries and apple are towards the left, so put them in the cauldron.

You will then need to turn the crank to the left of the cauldron, and the whole area will fill with water. You will need to swim and go right to an area where Floo powder can be used. Before you use it, go ahead and turn the red crank that is up and to the left from there this will open up a gate needed for later. In the new area after the Floo powder, you will then have to use Lumos on some hand vines in this area.

Go on down and you will find a red crank. Turn it, and some platforms will start moving. You’ll need those later, but right now, just get the hairpiece and go through the gate. From there, it is about making your way all around until you dump the hairpiece into that cauldron.

Go ahead and turn into Dobby, and go to the entrance where you first were. You should be able to enter in and get a Gold Brick.

Bonus Level 7

Both Harry and Ron are at this level together. Harry need to go to the right, getting rid of a dementor. He then needs to use Lumos on some Devil’s Snare here, and turn a red crank at the top of some stairs. This will open up a tube so Ron can send scabbers through.

Scabbers hits a button at the end of the tube that causes a platform to come down on Harry’s side, all the way to the left. He can then get up and use Floo Powder here. He should take the tooth with him, as there is a cauldron on the place he transports to. He can also grab the thorn and the skeletal arm nearby.

He can then drink the potion, and then pull a chain that is on the right. An area for Ron will open where he can cross a moving platform to get some earmuffs from the wardrobe. He can then go to the right and grab a mandrake, and then go to the left to shatter some glass and open a gate. He can put the mandrake down in a pot there.

Turning a red crank in this area will open up a gate, and the two characters can finally meet up. One of them can use Floo powder to get to where you started, and you can stand on a button. The other character will join, and a gate will open with a green crank inside.

The lava levels will fall, and there will only be water. Go ahead and get a Gold Brick.

Bonus Level 8

Harry and Ron are back together again. There is a polyjuice cauldron here, and you have to climb the stairs and kill the bogart to get the green apple. The hairpiece will be here on a small pillar. As for the red berries, use the Floo Powder and you will find berries where you are at.

Jump down to the cauldron and, once all ingredients are mixed, drink. You will then need to become a dark magic character, and use Floo powder to get up to where the tube is. Use dark magic on the big black ball, and send Scabbers in to push two buttons.

A gate will open, and you can then walk over to some other area. You will have to build a Lego bridge using some big bricks, but it isn’t anything you haven’t done before. You will then have to move some platforms so they stick on some purple blocks. You then need to jump on the platform and go to the right.

Be sure that the other character is with you, as it tends to stay back. You will need him or her to open up the door all the way here. Stand with them on two buttons, and then take out two bogarts. Go ahead and use Lumos on the Devil’s Snare, and turn the crank.

Go ahead and jump across the new platforms made in the mud and make sure the other character follows. You will then need to bounce on four mushrooms until you get to the top of the tower. When you do, stand on the button, and let the other character join you. The gate will open, and it is easy to jump to it to get a Gold Brick.

Bonus Level 9

It’s pretty obvious what to do here. Just stand on the two buttons and the doors will open.

You will notice a cauldron to make ageing potion here. You will need a banana, twig, and orange snake.

Go ahead and levitate the parts about the cauldron. This will make two buttons that your characters must activate.

To the left is an area with a glass tube. Send Scabbers up there, and he will have to crawl across some railing to get to another glass tube and hit a button on the bottom. A door will open, and Harry needs to come into this room so he can go to the snake door. After using Parseltonuge, a platform will descend, and you can get the orange snake for the cauldron.

Go back to the left, and you will see a fireplace. Use some Floo powder, and you will be in a small room with a crank. Use the crank, and the water level of the room will lower. You can then Floo powder back and grab the twig, and put it in the cauldron.

Go ahead and go to the right, and then to the wardrobe on the far right. Climb up the stairs, and you will have to levitate three part to form a letter “E”. The red and orange part are on the bottom, the green and yellow in the middle, and the blue brick goes on top.

Go on and grab the mandrake and walk it down to the area with the glass door. It will shatter the glass, and you can enter in to put the mandrake in the pot. Take the banana to the cauldron.

Once you drink the potion, it is easy to walk (rather slowly) past the age barrier and get yourself a Gold Brick.

Bonus Level 10

The first thing you will notice is the cauldron that needs thorn, tooth, and arm. Go on and grab the thorn and put it in, as it is close by.

Go ahead and go to the left across a moving platform, and then across another. Use Ron’s Scabbers to get into a glass tube. This will open up a door, and there is a mandrake in there. Go on to the Wardrobe and get earmuffs, and then snatch up the mandrake. Use it to burst through the glass. Go on and grab the tooth, and put it in the cauldron.

Go on and levitate some of the colored bricks and use them to form a bridge. You can then walk across it and come to an area where you need to move a platform into place. You should probably kill the big spider, and grab the skeleton arm.

Once all the ingredients are mixed, get some big strength and pull on the chain. This will open the gate, and you can use Lumos on the Devil’s Snare in the way.

In the next area, you will need to have Harry jump on one of the brooms and go through four hoops that look like they were made by fireflies. Go ahead and fly through them, and a door will open.

This next area will have a polyjuice cauldron here. You will have to levitate some weird looking bricks in various shades of blue to get it. The hairpiece is right there. The berries can be grabbed by just standing on a bench and having one of the other characters levitate you there. As for the green apple, it is in a tree. Just shoot at the stuff down there and you will find it.

You will then need to use the polyjuice to become another character that can dig, and stand on the two buttons that you dig up. A door will open, and you can go into the next area.

In the next room is the potion for aging. Go ahead and use the polyjuice to become Dobby. Dobby can go through all four doors and find all three ingredients. Watch out for Filch here, as he can do some damage.

Now that you have all 200 bricks. Go to Diagon Alley at Borgin and Borges and Levitate all the gold bricks until they form a door.

Walk in the door and start blasting. Keep an eye out for windows above your field of vision. You will then be rewarded with Character: Lord Voldemort.

Are you missing any rewards?  You shouldn't be if you have all of them and buy the last character.  See the Part 32: Index if you are.

On bonus level one do not drive the car into the garage...and then use the other character to try and get you out....I got both my characters stuck in the garage with the car. Couldn't do anything else!


Thanks for not helping 4 years ago

Did you even do level 5? Dobby can't open the door. You need a Ravenclaw to open it. Thanks for making me turn into Dobby and waste my time.

on bonus level 6 dobby doesn't open the door. Any ideas who does?

Dobby doesn't open any of the doors in any of the levels that this guide claims he does. Just look for the house colors next to each entrance and use a character from the corresponding house.
