In the 1990s, transforming playsets were released. Some could transform from one playset to another, such as a factory to a test track. Others could transform from giant vehicles to playsets, such as a 6x6 to a jungle. Earlier ones included one that could transform from a toolbox to a city. Another innovative release was a line of special boats in the 1990s. While past boats had merely sunk and were not intended for water use, these new sets could actually float.
