HOT WHEELS City Mutant Machines Set of 7 - Skullface, Spider Mutant, Power Tread, Street Shark, Cyborg Crusher, Nitro Scorcher  (Multicolor, Pack of: 7)

From the Manufacturer: City Underneath the Hot Wheels live the Mutant Machines. The result of a failed lab experiment, these half-creature, half-vehicle machines lurk underground waiting for their chance to take over the world! The Mutants don't "drive" - they bend, connect, slither and stretch with unique movement and styling. The vehicle's "wiggle" motion is due to its animal-like spine, and each can connect at the front and back to other cars to create a long Mutant Machine train. These vehicles have a life of their own and allow for enhanced storytelling and push-around play. For new, imaginative, underworld play possibilities get the whole fleet
