Before I get into this next area, this might be a good time to say that this last canister sometimes conked out on me one time while I was playing, and I had to Free Play the level all over again. Sometimes these Lego games have these glitches, and there is nothing you can do but essentially begin again.

Now, when you start going from rooftops, you will reach an area after Glider Batman must build a bridge for Robin. You can then become a super-strong character and move the dumpster and there will be batrope area for you. Use the rope, and break into the windows, and start wrecking things until you find the Seventh Canister.

You will then see the one canister that is trapped under a water tower. The only way to get to it is to remove a dumpster by a doorway with a super-strong character. You can then walk down there and to the left underneath the fan. Use an explosive (preferable as Demolition Suit Batman) and blow up the fan blades. Then become a high jumper and leap up to get the Eighth Canister.

You will soon come to an area where there is a magnet wall. Underneath it is an area with gas, and you can become a toxic-immune character and pull a lever to stop it. You can then blow up some shiny things, and get a lot of coins. That is about it, but you couldn’t do it the first time. Yeah, you probably thought you were going to get a canister or something out of that. So did I.

Now, when you get to the area with the helicopter, fly it to the left and not the right. You should be able go to a glass skylight, and jump out. Take out the glass as Sonic Batman, and then get the Ninth Canister.

There is another area to go to that is on the right. You will need to become Sonic Suit Batman to break all the glass, and then there will be a place full of water. If you dive in as Aqua Robin, you can’t get down there to get the canister. What you need to do is through in an explosive penguin as Penguin, and that should be enough to blow up the gate that is stopping you. Go ahead and get the Tenth Canister.

From here, you can go and use the trapdoor and get to a balcony, and there will be a glass window. Sonic Batman can shatter it, and you will have the Power Brick.
