Phineas and Ferb create a giant skate track and build skate but forgot they didn't know how to skateboard so they get assistance from Tony Hawk. Pretty soon They travel all over the world to skate but, Doofenshmirtz creats a Non-Energyinator to slow everyone down on any sports so he can be the fastest. Meanwhile, Phineas and Ferb are the only ones not hit by the ray so they try to encourage everyone with skating.
