The outskirts of Hot Wheels City have been infiltrated by villains stirring up trouble. The Joker has taken over the amusement park and has re-named it The Joker Funhouse. Drive up the ramp on the side of the Funhouse and be careful to avoid the swinging mallets and free trapped friends and defeat The Joker. Use the elevated ramp and the Batmobile in the Killer Croc Sewer Escape set to slide down the sewer at top speed to get past the enormous crocodile and save the city. Mr. Freeze takes over the Gotham City police department and it's up to kids to launch Batman around the ramp to defeat the villain and free the police in the Police Takeover Play Set. Also included is the Batman Repair Bunker Play Set where kids can go to fuel up and fix the Batmobile. Use the special platform to take the car to the next level and launch into the next adventure. Each set comes with a Batmobile for battling the bad guys and their own mini-figure. Sets connects directly to the Batcave and other Hot Wheels City sets (sold separately) with a brand-new connection system, still compatible with your orange track.
