In Smileyland, the cars are all made of cardboard. The characters use them as a means of transport in several episodes. They come in many different colors, such as red, black and cardboard brown.
- Some of them have the letters PTM on their license plates, which is likely to stand for "Pays Trop Mignon" (the French name of Smileyland).
- A more futuristic one was shown in "Let's Play Super Future" (and its sequel "Let's Play Back to the Past"), which could travel through time if driven at a speed of 88mph. This car was a reference to the DeLorean from the movie Back to the Future.
