Under the Hot Wheels® City live the Worms. Resulting from an underground experiment gone wrong, these creatures that are half vehicles and half worms are ready to take over the world! The Worms don't "drive" - they bend, connect, slide, and stretch with unique movement and style. The vehicle's characteristic movement is due to its spine, and each one can connect front and back with other vehicles to create a long worm. Unique vehicles for incredible stories and endless play. For new imaginative play possibilities, collect them all (each sold separately).
