## Abstract

The purpose of the present invention is to provide a transformable toy car, the driving of which can be controlled from a remote location and which transforms from a car shape into an arbitrary second shape, thereby exposing the lower surface of an attached card when an arbitrary card is attached to the car while the car is traveling.
