As soon as you enter the sewers’ second area, use the nearby checkpoint station to save your game. Then start smashing your way along the ramp until you reach the area’s central platform. Once there, Killer Croc emerges from the waters below, and the battle begins! Begin the battle by smashing all of the objects around the central platform. Build their bricks into a familiar Hazard Suit contraption for Robin. You need to fill it with 25 LEGO parts. You may have discovered a few LEGO parts while navigating the sewers, but you need more to activate the contraption. Go right or left to find a spot where Batman can use his Sensor Suit to detect a button (there are two such spots). Once you reveal a button, tag to Robin and leap onto it to open up a trapdoor. Whoa—Killer Croc bounds up from the trapdoor, along with a whole bunch of LEGO parts! Ignore Croc and hold the Attack button to suck in all of those LEGO parts. Repeat this on the other side of the area, using Batman’s senses to detect the button as you did before.
Make Croc bound out of both trapdoors to find all of the parts you need! Killer Croc won’t emerge from the trapdoors if he’s already lurking around. Wait for him to leave (he dives underwater), remaining on the button until he pops up from the trapdoor. Deposit 25 LEGO parts into the contraption, and it spits out a familiar cannon. Hop onto the cannon’s gunner seat and press the Attack button to fire a net at Killer Croc that pins him to the wall, bringing this level to a dramatic close. Use a projectile attack to destroy the lasers protecting the door on the left. Head up the stairs on the left and use Cyborg's Demolition Suit to destroy the silver box. Interact with the resulting bricks to build a Techno Panel. Interact with the panel to unearth the token for Robin's Sphere Suit. Use Cyborg's Sonar Suit to shatter the glass it's encased in. Once Robin has his new suit, switch to the Magnet Suit and interact with the blue object on the left. Change to the Sphere Suit, hit the Interaction Button to encase Robin in a clear, plastic ball (we're sure there are air holes) and roll onto the Sphere Slot.
Roll on the slot to open the door. Advance to the next area. In the next area, use Cyborg's Demolition Suit to destroy the silver object on the right next to the screen with Joker's face on it. Interact with it and the screen will activate. Click on the center box on the screen and the boxes will shuffle around. Keep your eye on the box you clicked as it moves around. When the boxes stop moving, click the box and if you chose the correct one you'll be rewarded with a purple stud and a token for Cyborg's Giant Suit. Don't worry if you get it wrong - just try the others. Follow the ghostly blue studs to the left until you find the object with two green handles. Use Cyborg's Giant Suit to grab the handles and remove the object. Now use the Giant Suit to smash through the cracked door just beyond and into Level 4. EditMinikit 1 Knock down the six presents dangling from balloons. The first two are in the area where you fight Firefly, the other four are in the room beyond where you fight Cheetah.
Raise Wonder Woman's bracelets or use a charater with a shield (like Alfred) to walk through the fire to reach the ones in the background. EditCharacter Token - John Stewart (Free Play) Use magnet power to open the blue grate on the left side of the area then fly up and claim the Character Token. Hey, let's start out with a boss fight! Avoid Firefly's attacks until a few bricks fall into the play area. Interact with them to build a Flash Pad. Have Flash use the pad and select the highlighted areas to build a water cannon. Hop in the cannon and squirt Firefly until his health hits zero. Then spray the flames on the stairs until an orange plug is exposed. Switch to Wonder Woman and grapple the plug to clear the fiery debris out of the way. Let's have another boss fight! EditMinikit 2 (Free Play) Walk through the fire on the left side of the room with a shield character like Alfred or Lex (Wonder Woman can use her bracelets) to reach the back of the room.

Let Cheetah pounce on you then switch to your partner and smack her. She'll run off and some minions will enter the room. Destroy them all and Cheetah returns. Once again, let her pounce then switch characters and smack her. She'll retreat too the ceiling and fire a laser that will destroy a nearby object. Interact with the resulting bricks to build a Deflect Pad. Have Wonder Woman stand on the pad and deflect the laser back up at the gold portion of the laser. More bad guys storm in. Defeat them and Cheetah will return and pounce. As always, switch characters and smack her. Keep this up until she's down for the count. EditMinikit 4 Head over to the right and use Robin or Cyborg's Magnet suit to interact with the blue object. Open both doors for a Minikit. EditMinikit 5 Destroy five glowing white signs.

Interact with the Sphere Slot and a Fueling Machine will appear above you. Switch to Cyborg and ride the updraft to the Fueling Machine. Gas up his Space Suit and follow the trail of studs in the air to the platform on the right. Switch to the Giant Suit and grab the green handles on the wall to remove the panel. Destroy the the gold object behind it to disable the lasers blocking the blue magnetic pipes. Switch to Robin and use his Magnet Suit to march up the blue pipes to where you left Cyborg.
Change into the Techno Suit and interact with the Techno Panel to call the elevator. Beat up the bad guys that pour out and before you leave, head back to the Fueling Machine to top off Cyborg's Space Suit. Now return to the elevator, position each character on a button and ride it up to the armory. EditMinikit 7 There's a Minikit floating in the back corner of the upper walkway on the left.

Light up the middle of the area to find a few of those hopping LEGO bricks and interact with them to build a lamp that reveals a gold wall. Have Cyborg cut a hole in it to find Solomon Grundy hiding inside. Switch to Cyborg's Giant Suit and punch the crate Grundy's hiding in. Defeat Grundy by following the onscreen prompts. Turn on Robin's Illumination Suit (recharge it if necessary) and you'll find a box with a shiny silver bit.
