Lego Batman Strategy Guide 93: Stealing the Show, Free Play, Part 1
One of the first things that can be done here is go up and up for some serious bonuses. The first thing that has to be done is to remove the big blue object that is near this first area as a super strong character. This will create a pile of metal tiles which then need to be twice built up to make a place where Magnet Suit Robin has to climb. When he gets to the second level, he needs to go left and jump to the next area.
Here he can rescue Hostage 19/25. He can also get the Fifth Canister. If he goes around the corner, he can even get a purple stud. Not bad.
Go ahead and jump down and go to the right in order to glide to the other side. When you get to the area by the fans, you may notice two shimmering pots to the left of them. Go ahead and use a little Poison Ivy magic on them, and two plants will grow from that spot. Poison Ivy and jump from one to the other, and get to the top, where she can grab the Sixth Canister. If you want, there is something to blow up, but it doesn’t give much in the way of studs.
Just go over the fans this time. You will need to go to the window with hearts as some sort of female character to gain entry. Go ahead and go through the area with the police helicopter. Here is how to defeat it in case you forgot: Stand on a blue area until the police chopper tracks you and hovers over you. He will first drop a smoking thing and then a bomb. Move to the red button which will turn green after you stand on it. The blue trap door will open, and blow the bomb back on the helicopter, resulting in a nice explosion. Repeat two more times.
Go ahead and hit those dual steering-wheel shapped pressure pads to stop the fans. You should be able to glide to the window washer area thing. Use the lever in the next area to reverse the direction of the fans upward.
When you get to the part where you need to push the statue over to get to the next area, you need to go all the way to the left. There is a metallic wall there, and you need to become Magnet Suit Robin in order to get to the top of a roof. The Seventh Canister will be there for you, so go ahead and grab it.
