The Hot Wheels™ City Nemesis Launcher Assortment features two kid-favorite nemeses -- the T-rex and shark -- as super-cool car launchers (sold separately). Both the Hot Wheels® Dino Launcher and the Hot Wheels® Shark Launcher feature cool challenges where kids must launch cars with the right force or risk getting stuck in the nemeses' jaws. These compact toys can also be played with on their own for big-sized fun on a smaller scale. Each includes one 1:64 scale Hot Wheels® car and are exciting gifts for kids four to eight years old.
