5H. Big Trouble in Little Gotham =

Mini Ace Chemicals: Smash canisters to assemble a rotator switch. Use it to release the Hazard Suit canister. Collect pieces for the suit: some on the roof (sonic glass, ride fan), some in tanks (use Magnet), and some behind a silver truck (use explosives). Assemble the pieces and use Giant to throw the canister at Brainiac.

Mini Fairground: Use Electric Joker on the ride on the back left to break it. Assemble the pieces into a Sphere Mount. Use Sphere Joker to open the back. Have Flash jump up walls to the top, then run right to the Ferris wheel. Assemble a treadmill from nearby pieces and run on it to break the Ferris wheel, releasing pieces for a Flash Pad. Assemble the Flash Pad and use it to create a roller coaster track. Have Joker use his Electric charge on a generator to send cars rolling.

Mini Botanical Gardens: Find three dig spots. As Grundy, climb steps on the left to smash cracked floor for the first spot. The second spot is left of the greenhouse under leaves. For the third spot on the right, grapple down a ladder, climb up, and grab the DIVE SUIT. Drop into the water tank and laser two gold caps to reveal the third dirt pile. Have Cheetah dig up all three spots. Then, have Robin laser the gold buds to enter the greenhouse. Use Grundy's Swamp Pad to get a launcher, then have Robin pull the orange hook.

Big Skull Ship: Avoid Brainiac's ship's arms. When an arm burrows and pops up, hit the glowing spot with a Batarang or tiara. Blast the silver spot with Batman's Power Suit. After both arms are busted, use Sense to find pieces for a Shield Pad. Assemble it and have Wonder Woman reflect the laser at the ship's red teeth. Once teeth are busted, assemble a Flash Pad and use it to defeat Brainiac.
