5P. Bonus Level: Same Bat-time, Same Bat-channel! =

Batcave: Build the Batmobile. Smash blue pieces to create a magnet wall. Use Robin's Magnet power to climb the wall and step on the red switch to break water pipes, allowing Batman to reach the ledge. Head left, take the charge from the generator to reveal Batmobile parts. Use the electric charge on the generator near the conveyor belt for more parts. Go to the back, use Batman's Sense to reveal a hook, pull it to lower a ladder. Climb up, use the green wall to hit three wire clamps, dropping a box that creates a Tech Panel. Use the Tech Panel with Robin to reveal silver boxes. As Batman, hold B to pull out a Bat-Bomb and blow up the boxes. Assemble the pieces to finish the Batmobile and hop in.

Batmobile Pursuit: Batgirl joins in a Whirly-Bat. Alternate between characters. Batgirl fires projectiles, and the Batmobile holds X to fire its laser. Fire the laser at the gold part of the steamroller to expose a hook. Switch to Robin and mash B to pull the steamroller and disable it.

Groovy Diner: Tag Catwoman twice with a Batarang, then use Sense near her to find a silver block. Throw a Bat-Bomb at the silver block to knock her down. Assemble the pieces left behind. The Joker appears; punch him when he's vulnerable (he'll zap you if attacked directly). After his health is depleted, he moves behind the counter. Penguin appears. Use Sense on the left, climb the pole to the upper level, and flip the switch to drop the stairs. Head up with Batman, tap B to activate his cape shield, approach Penguin, and punch him. Use Sense and pull the hook to drop pieces on the ground floor. Assemble them. Use the X-Ray wall to make the Riddler appear, then punch him. The Joker reappears with a bumper car. Punch thugs until he crashes, then assemble the final pieces. Have Robin use his Magnet on the assembled object.
