In Jaywalker, you play as a head in an intersection, determined to smash up cars!
In this mini-game (fully titled Jawalker Take Back The Streets) you play as a floating head who goes by the name of Marjorie. This head loves walking around in an intersection, causing cars to swerve around her and crash into junk. What a sweet floating head she is.
So, the idea is: walk in front of cars. Make them avoid you, thereby causing crashes. You get points for making them smash into lamps and signs, as well as the island in the middle of the road. You get more points for crashing cars into other cars, and more again for repeating the process in quick succession.
Of course, this is all done with an environmental message in mind, so kids - do your bit for the enviroment, won't you? There are different types of cars, some won't swerve and its game over when you get run over. Point scoring is the only goal here, so its a real mini-game. Don't expect anything big.
