Abstract: A transformable toy which has a playful aspect in that an additional movement is produced in a process of transformation, although the movement is not directly related to the transformation, as well as which has portions which can be transformed without being manually operated by the user. The transformable toy, which is reversibly transformed between a first configuration and a second configuration, includes a first member and a second member. The second member is connected to the first member in a vertically pivotable manner through a connecting member. When a lock member provided on the first member is functioning, the second member constitutes a first configuration with the first member in a fore-and-aft positional relationship. When the locking function is released, the second member pivots downwardly under its own weight and constitutes a second configuration with the first member in a vertical positional relationship.
