The event consisted of several billboards (which have been previously used to advertise the Good Dinosaur event and the Kung Fu Panda 3 Event) depicting angled shots of 2 characters from the movie. However, unlike the two mentioned events, this event had no prizes and is not recognized as a Roblox event. It was, instead, a paid promotion accepted by Defaultio, like the Jimu Robot Sponsorship.
There were more Cars 3 billboards than any other previous sponsored event. There were two in the Main Biome, two in the Mountainside, two in the Safari, two in the Taiga, two in the Tropics and one on the Ferry.
