Episode Summary
Silver the Hedgehog is sworn into the O.W.C.A. after his efforts in stop Dr. Doofenshmirtz earlier that month. Silver is so excited, but he needs to quickly stop Dr. Eggman after his ceremony because Eggman is rumored to be opening another portal to the Tri-State Area. So Silver springs into action, but is stopped by Sonic, who should be the one springing into action, which he does with Tails and Amy. Eggman is building a portal, and he pushes Sonic and Tails and Amy in. Silver was mad that he didn't get to stop Eggman and that his friends were in the Tri-State Area.

Phineas and Ferb were busy building their own highway system. They call it the Fletcher Interstate. Suddenly, Sonic and his friends appear on the highway. They start running away from some robotic police men. Just like Speed Highway in the SEGA Dreamcast game Sonic Adventure! Ah, throwback. The boys had Haven, Mallory, and Buford over. The three wonder who those people are. Phineas notices that Sonic and Tails have returned, along with Amy. Doofenshmirtz notices Sonic is back and makes sure he will never go back home.

Doofenshmirtz throws some TNT onto the Fletcher Interstate. The highway explodes making cars go flying all over the place. It sends Sonic, Tails, and Amy flying into a trap of Doof's. Phineas and the gang save them and return them to home.
