The Chemical Factory is the eleventh hero level in the Nintendo DS version of LEGO Batman: The Videogame. It is the first hero level of The Joker's Last Laugh.

Story

In his secret office in Amusement Mile, the Joker teaches his group a test in which he uses laughing gas on one of his goons and then knocks him unconscious. He then shows his magnificent plan to his group. Their plan is to obtain toxic gases from Ace Chemicals and then blow up Gotham Cathedral. This will cause toxic gases to be created all over Gotham City, making everyone laugh.

To begin his plan, the Joker heads to Ace Chemicals with the Mad Hatter. There, they enter the control room and interrupt two police officers, one of whom was playing a Nintendo DS. However, the sleeping police officer manages to press a button to activate the Bat Signal. Batman and Robin board their air vehicles and head to Ace Chemicals. Heading into Ace Chemicals, they come to the engine room. In that room, they meet the Mad Hatter, who had hypnotized six policemen. The heroes use their boomerangs to knock off the policemen's helmets, returning them to normal and helping them defeat the Mad Hatter. The duo manage to defeat the Mad Hatter, who refuses to tell Batman the Joker's location. Before Batman beats up the Mad Hatter, he tells him that the Joker is at Amusement Mile with Harley Quinn. Revealing the Joker's location, the duo leaves the Mad Hatter hanging and heads to Amusement Mile. As the Mad Hatter is left hanging and unable to defend himself, the police take him to Arkham Asylum.

Walkthrough

You start at the entrance to Ace Chemicals. Three Joker Goons will jump from the factory roof and attack you. Defeat them and two more Joker Goons will come. Defeat them too and you'll have to open the front doors. To do this, build a suit swapper on the right and use it with Batman to put on the Demolition Suit. Then, place a detonator on the door and detonate it to destroy the red and black boards protecting the doors. After this, you will need to make two red lights turn green to open the door. For the red light on the right, destroy a red lock on the right with Batman and destroy a red box to build a square button. Step on it to turn the right red light green. Repeat the same on the left side for the left red light. With both red lights green, the front doors will open. (Make sure you have destroyed the red and black boards, otherwise the doors will not open and you will have to step on the buttons again.) Go through the newly opened doors to reach the next area.

In the next area, defeat two Joker Goons and you'll see that the ledge ahead is very far away. To reach it, you will have to form a bridge. First, use Batman's Batarang or Robin's Birdarang to hit a glowing red target on the right and turn it green. This will allow you to build a suit swapper. Use it with Robin to put on the Bio Suit. With the Bio Suit, cross three toxic gases to the right and step on a square button to turn off the gases so Batman can reunite with his friend. Switch to Batman and destroy a red box to build a grapple point. Use it to reach the ledge above and step on a button to build a metal wall. Then, switch to Robin and use another suit swapper to put on the Magno Suit, which will allow Robin to reach the ledge above. With both characters on the high ledge, have them pull two levers to turn the right red light green and extend a bridge. However, you will need to turn another red light green to open the door. To do this, go left, climb a slope and build a metal wall. Climb up that metal wall with Robin, walk on a tightrope to cross the gap and jump to the low platform on the right. On that platform, build a lever and pull it to raise a platform in the middle of the purple acid. This platform will allow Batman to reach the platform with Robin. Switch to him, destroy a red box to build a lever, and pull it to reveal pieces on the ledge in front of the bridge. Go back to the center, cross the bridge you extended and build two buttons. Then, have both characters step on them so that the left red light turns green. With both red lights green, the door will open, but three Joker Goons will come out. Defeat the goons and go to the next area.

In the next area, two Joker Goons will jump from the ledge above. Defeat them and you will have to find three blue bricks and place them in a build-it machine. The first blue brick can be found inside a barrel near the ladder in the upper left corner. Destroy the barrel to reveal the blue brick, grab it and place it in the build-it machine. To find the second blue brick, climb the ladder, build a box and push it into the slot in front. This will cause blue stars to appear on the vending machine on the right, which will cause a red light to turn green. Destroy the vending machine to reveal the blue brick, grab it and place it in the build-it machine. To find the third blue brick, climb the ladder again and go to the far right. At the far right of the area, destroy another barrel to reveal this blue brick. Grab it too, take it to the build-it machine and place it there. When you place the three blue bricks in the build-it machine, you can build a button. Step on it to make another red light turn green. You will only be missing one red light. To do this, climb the ladder once more, go right and use Robin on a suit swapper to put the Bio Suit back on. With the Bio Suit back on, step on a square button in a toxic gas to build a lever on the left. Pull the lever to turn the third red light green. With all three red lights turning green, pull a lever in the center to flash the lights and build a platform on the left side. When you build that platform, the others, including the one you built, will rise. Jump on the platforms and go through the open doors to reach the next area.

In the next area, two Joker Goons on the right will attack you. Defeat them and pull a lever three times to make three green lights turn red. With all three green lights turning red, the tubes will explode and you can build a button. Step on it to reveal a stunt pole on the right. Cross the acid on the right with Robin and use a pole point to swing on the pole and reach the high platform. On that platform, step on four square buttons to drain the acid, allowing Batman to cross. Switch to Batman, use a suit swapper to put on the Arctic Suit, cross two freezing gases to the right and defeat two Joker Goons. Use another suit swapper to put on the Demolition Suit again and destroy two red boxes one by one to build two vent covers. These vent covers will block the freezing gases and allow Robin to reach the far right. Have both characters step on a large button to open the doors that will take you to the final area.

In the final area, jump onto the central platform and you'll face the Mad Hatter in a boss fight. He will stand on a high ledge and send two hypnotized policemen to attack you. Watch which button the Mad Hatter is going to press to avoid a purple gas. Then, use Batman's Batarang or Robin's Birdarang to remove the helmets from the hypnotized policemen. This will return them to normal and they will pull two levers to open the front glass. Use Batman's Batarang or Robin's Birdarang again to hit one of the three glowing red targets, which will cause the glass on the container behind the Mad Hatter to begin to shatter. Repeat the same process three times to break the glass of the container, defeating the Mad Hatter with acid and ending the level.
