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.
