You know that McDonald’s and Mattel/Hot Wheels have a relationship that goes back decades. Once again, Hot Wheels are available in McD’s Happy Meals. There are six models available. They’re plastic, not diecast metal. However, there’s a cute gimmick this year: pull-back motors. The link below takes you to the HapMeal toy page; if you click on a car image, you get a pop-up video showing a child’s hand operating that car. Hard to judge from the videos whether the models are in scale with mainline models.
Personally, I’m 50/50 on Twin Mill, and about 25/75 on Bone Shaker; the others I’m skipping entirely. Oh, apparently each model has a QR code on the bottom, which you can scan with your smartypants phone to unlock a game.
