After watching a commercial for an all-terrain vehicle, Phineas Flynn decided that he and Ferb Fletcher could build a better model - one that could drive on literally any type of surface. It was built with an electromagnetic motor, super rubber tank treads, a high speed ceramic body, hydraulics, an old remote control, and a rocket mode ("The Secret of Success"). A recreation of the ATV was later used to repel 2nd Dimension Heinz Doofenshmirtz's invasion of the Tri-State Area (Phineas and Ferb The Movie: Across the 2nd Dimension).
