This is a completed toy designed for children and/or collectors.
Here's a fun, simple transforming toy from Takara Tomy and their "Hyper Rescue" series. These toys come with an "AC Spot Base" that initiates the transformation to "Active Mode" as soon as the toy is docked to the base. They do not require any batteries. This "Dump Dozer" switches between dump truck mode, and wheeled dozer mode.
