I've been trying to figure out the name of a book I read as a kid for years so I'm gonna put it out here

There's a cool kid and he get a hard light medallion that can turn into a cool car. Kids go to a junkyard and solve video game and cartoon puzzles allowing them to enter a giant mario pipe- this takes them to a vast underground amusement part. The park was complete with food, rides, roller coasters, video games and computers, a meta-material floor that gets soft under force, making falls etc completely safe.

There's a sick RC car course, and they wear a VR headset and gloves and actually drive the car.

I was about fourteen, so the year was about 2013 and I think it was relatively new.

Anyone know anything about this?
