Five-In-One

This is the story of five teenagers who pilot corny mecha vehicles that Lego together to form an ugly towering robot that does weird dance moves not minding whether the alien monster from outer space would attack it while it's doing the cha-cha-cha. *whew* Oh well.

The robot is composed of five parts. The leader pilots the head and torso. Two of the other parts are the arms, while the other two parts form the legs. And, by the way (as if it weren't obvious enough), you're one of the pilots. Which vehicle do you drive?
