The 81-piece set contains a variety of colourful smooth component blocks that come as 4 distinct subsets but can be interchanged to extend the play value. Several of the blocks have simple connectors to allow for more adventurous construction, and each vehicle has a connector option to fix the driver on the front. The vehicles all make a range of relevant sounds, including alarm beeps, engine sounds, horns, sirens, and a friendly bus tune. Each vehicle also displays a range of flashing lights in white, blue, green, red, and pink.
