You will then need to shut down the three jets. You will then need to use your magnet suit to head up the ramp and pull the leaver to raise the grapple to the top. Then you will need to jump into the ice and freeze them, this will cause a large solid platform for you to cross on. Once that has been done,you will need to pilot the Batarang into the equipment to fill it up with the purple slime. When either of the two characters head to the top, you will need to have to step on the switch, and then the other character will need to make their way up the stairs after the other character. He will then need to jump onto the circle switch. Head across another gap and push the lever for Robin to cross, he will then need to get a hold of the hook and grapple back to batman. This will then make a moving platform, jump onto the platform and pull the lever to open the door on the other side. You will then need to push the large box off the edge and break it making more Lego pieces. Using the Magnet suit to get up the ramp and put the grapple point together at the top, this will make it easy for both characters to get across. Once you have made your steps, you will need to head up them and make your way across the floor. Then, you will need to aim for the two large ice-pops that are hanging from the roof, once they have fallen off the roof, you will need to put them together and make a staircase. Once you have made it across the gap, you will need to put the parts together to mend the bridge. Before you make your glide across the gap, you will need to push the crank you just made close to the jet, this will allow you to get across the gap safe. Now you are inside the factory, you will need to pick up the items to make a large suit charger for batman.

You will now be able to make your way into the factory.
