Alyson Stoner is all smiles as she arrives at the Phineas And Ferb, Gravity Falls, and Fish Hooks panel during the 2012 San Diego Comic-Con held at Hilton San Diego Bayfront Hotel on Saturday afternoon (July 14) in San Diego, Calif.

There’s some exciting new things happening with the hit animated show — including an all-new two-part summer special called “Where’s Perry?”

Premiering Thursday, July 26 @ 9PM ET/PT on Disney Channel, part one of the special follows Phineas and Ferb as they embark on an African safari vacation while their loyal pet platypus Perry stays back in Danville to handle a Dr. Doofenshmirtz emergency. As the story unfolds, Dr. Doofenshmirtz tries to take over the OWCA with his Ultimate Evil-inator, but it inadvertently zaps Carl the Intern, turning him evil. Several of Dr. Doofenshmirtz’s “-inators” hit Perry, causing him to disappear and quickly prompting the question: where’s Perry?

Meanwhile, in Africa, Candace frantically searches for a cell phone signal to get through to Jeremy back in Danville while Phineas and Ferb build a highly unconventional vehicle to explore an unchartered gorge.

The search doesn’t stop there — Disney will launch a cross-country Perry the Platy-bus tour. Along the way, fans can join the mission to bring Perry back home and, via Augmented Reality, can virtually interact with Phineas, Ferb and other characters. The tour will travel to state fairs and tourist destinations across the country this summer.

“Where’s Perry?, Part Two” will air Friday, August 24th on Disney Channel. 10+ pics inside…
