The utility model provides an even the thin transformable toy that also can obtain abundant intensity of the thickness of plate body. A serial communication port, a plurality of component parts are connected and are configured into adj. Tabularly through adapting unit (4a~4d), the constitution can be folded for the above -mentioned component parts partly at least of the above -mentioned adapting unit through partly each other with overlapping, and constitute and to move for other parts for partly at least in each other of the above -mentioned component parts that overlaps integratively, this transformable toy gains the other form after partly at least in each other of above -mentioned component parts that a plurality of component parts configured a platelike form and overlapping into moves integratively reversiblely.
