Part 1: Dank sewer path
You start out in a partially flooded area with the way forward blocked by debris. As either Batman or Robin, grapple up on to the ledge right next to the entrance. Jump across the multiple ledges to reach the lever. Pulling it causes two drains to activate, draining surrounding water out. Now, go around and destroy the various crates and containers. After you've cleared the area, you should be left with some large yellow blocks and piles of brightly-colored debris.
 * 4 Minikits, 1 Character Token, Red Brick, Adam West

Use the blocks scattered around everywhere to build a waste disposal machine, causing a token to appear in front of it. Collect the token as Robin to unlock his Hazard Suit, which lets him move over green toxic waste without getting harmed. More importantly, the Hazard Suit comes with a vacuum that lets you suck up the yellow, red and green objects lying around. Collect 25 pieces and deposit them into the machine, which spawns a massive cannon beside it. Use your grappling hook to raise the cannon into position, after which it will automatically fire at the debris, clearing the path forward.

Among the destroyed debris is a token that unlocks Batman's Sensor Suit. The Sensor Suit lets Batman sense hidden objects and see through walls, and even comes with a useful stealth mode. You can test out the Sensor Suit's abilities by using it among the swarm of bats on the wall, revealing a grappling spot. Hook on to the grapple spot and pull of the latches to cause a screen to extend and expand, displaying a wall of green bricks. Use Batman's Sensor Suit to see through the bricks. Rotate the pipes to form a continuous path between both ends, then release the two valves on both pipe endings. With the pipes connected, water can now flow into pit to the right, letting you swim across or jump across using the wooden palettes.

As you round a few corners, you're confronted with either deadly fire-spewing pipes or a huge pool of toxic waste. Walk through the toxic sludge as Robin and use his vacuum/air gun to destroy the shining yellow latches on the wall, causing a panel to fall to the ground. Destroy the panel and surrounding objects to get parts for a motor attached to the wall, resulting in a ladder dropping down. Climb up the ladder and move over to the gas pipes. Stand on either button to temporarily disable the fire streams, letting Batman get across. Now that Batman has rejoined you, go back to the subway carriage and use the Sensor Suit to uncover a grappling spot.

Grapple on to the hook to pull down the rail's support column to cause the track and carriage to tumble into the sewage. Walk up the submerged train and enter the train on the adjacent rail. From there, jump to the completely sunken carriage and climb up the ladder there. Destroy the crate for parts to build a tightrope, creating another path from the track on to the platform while letting you collect a few more studs. Use Robin's Hazard Suit to move across the toxic sludge, then pull the lever to open some hatches, draining away most of the waste and creating platforms forward.

On the other side, use the grappling hook to pull down a ladder. Climb up the ladder and head to the sewer grate in the background. Destroy the glowing crates to get parts needed to build a grappling spot at the center if the grate. Pull on the grate with your grapple to remove it. Just in time as well, since you'll catch a glimpse of Killer Croc in the tunnel up ahead.

Part 2: Killer Croc battle
After some further exploration of the sewers and a discussion about fear, Batman and Robin come face-to-face with Killer Croc! This powerful brute is larger and stronger than before, so you can't hope to harm him with normal attacks. Killer Croc is at least smart enough to fight from a distance, tossing heavy objects as you with no fear of retaliation. He will also rally his own band of Croc Henchmen to fight.Occasionally, he'll even leap right on to the stage, ripping fissures across the ground with his powerful punches.
 * 6 Minikits, 2 Character Tokens

First, destroy all the objects on the platform in front of Killer Croc, then use the pieces to build a waste disposal machine. Use Batman's Sensor Suit and head to either side of the platform, then activate your heightened senses to reveal a button on the floor. Jump on to the button to make Killer Croc pounce out from the water below, scattering pieces of vacuum-able debris on the ground. Do the same on the other side, then suck them all up with Robin's Hazard Suit. Dump them in the machine to make another cannon pop out. Hop on the cannon to end the stage!

The cannon fires a huge net that ensnares Killer Croc against the wall. As Robin tries to capture him, Killer Croc breaks free of his shackles and escapes! He is apparently working with the rest of the Legion of Doom, having stolen the sewer maps from the City Records office. What is this nefarious group of supervillians planning to do?

Minikits

 * 1) (Free Play only) The very first waste disposal machine you built is still good for one more use. All you need to do is vacuum up 25 more LEGO pieces. Be thorough, as you should only have exactly enough pieces to do so. You should have 5 pieces extra after the cannon, with another cart full of pieces near the flaming pieces. Next, a cart of pieces is located at the end of the intact rail track. The next cart can be found on an alcove near the two hatches. The last few pieces is in a cart on the platform above the sewer grate. Once you've collected all of the pieces, dump it into the machine to get a Minikit.
 * 2) (Free Play only) There are five golden toilets scattered around the sewers. The first is after the pit you had to flood. Two more golden toilets can be found on both floors near the flaming pipes. The next toilet is on the ledge above the hatches. The final toilet is near the end of Part 1, next to the stranded Adam West.
 * 3) (Free Play only) At the fire-shooting pipes, use a character with a laser to destroy the golden plate on the right pipe, causing it to burst in flames.. Then, use someone with the Magnet Suit to rotate the water valve nearby and have it put out the fire. Once the fire is extinguished, you'll find a Minikit where the gold plate was.
 * 4) (Free Play only) Fly on to the ledge above the hatches. You should see a goon behind the glass screen. Use mind control to control the henchman, then move him right whenever the machinery moves down until you reach the Minikit at the end.
 * 5) (Free Play only) Near the Checkpoint in Free Play, you will find Bat-Mite, who wants you to get him a pair of transparent pants. At the secret entrance described in Minikit No. 9, there is a washing machine that must be pried open with the Magnet Suit. Inside is a pair of those pants. Get it back to Bat-Mite for your Minikit.
 * 6) (Free Play only) Use a laser beam to burn down the four golden lamps hanging around Killer Croc.
 * 7) (Free Play only) Fly to a pipe high up on the left side of the arena and use explosives to blow up the metal plate. A leak will spring, causing a Minikit to burst out.
 * 8) (Free Play only) Fly to the very back, near where Killer Croc is standing. The Minikit is hidden behind a pipe on the right.
 * 9) (Free Play only) Near the right button is a blue gate. Use someone with a Magnet Suit to pull the gate apart, letting you enter a secret area. Use a laser to cut a rectangle out of the golden wall, letting you get the Minikit behind it.
 * 10) (Free Play only) Again in the secret area, there is a swamp pad in the lower-left corner of the room. Have Solomon Grundy dive in to find a massive silver crate containing a Minikit within. Blow it out with explosives to claim the prize inside.
 * 11) (Free Play only) On the right wall of the hidden area is a glass pipe and ball contraption. You must use the Magnet Suit to guide the ball along the pipe, then stand on the buttons whenever the ball reaches a piston to let the ball continue on. Once you get the ball to the other end, the Minikit will appear.

Character Tokens

 * Croc Henchman: (Free Play only) At the starting area, there is now a ladder leading to a pool of water below. When you descend, you'll see 4 ducks swimming around with a single duck boat. Hop on the duck boat and ram into all the ducks to get this token.
 * Bane: (Free Play only) Near the checkpoint is a shallow pool of water. Use a character with a freeze ability to create a sculpture of Killer Croc from the pool, then melt it down again with a laser to get the Bane token.
 * Black Manta: (Free Play only)

Red Brick
(Free Play only) Fly on to the platform above the removable sewer grate. As Plastic Man, use the red panel on the ground to shapeshift into a water pump, pumping water into the inaccessible chamber behind the glass well. Once the chamber is filled with water, the Red Brick inside will float out and be deposited near where you stand. This Red Brick gives you Score x2, which multiplies all studs collected by 2. It is good for farming studs, but requires a lot of saving up to buy.

Adam West in Peril
(Free Play only) At the end of Part 1, you'll see Adam West stranded on a raft being circled by a shark. You can't kill the shark with anything, but there's a more pacifistic solution nearby. On the platform above, there is a swamp pad you can use as Solomon Grundy, which causes you to unearth a can of shark repellant! Jump on the top of the repellant to spray it into the water below, driving away the shark and freeing Adam West.
