FOR USE IN SCHOOLS AND LIBRARIES ONLY. Phineas and Ferb create a swimming pool full of gelatin and have loads of fun—until it's accidentally hit with Dr. Doofenshmirtz's latest device, a ray designed to turn everything evil.

Phineas and Ferb need a tool that hasn't been invented yet, so they hop in a time machine and head 20 years into the future! Unfortunately, they're spotted by Future Candace, who follows them back in time to bust them on the day they built their giant rollercoaster.

When Phineas and Ferb develop an indestructible exoskeleton to take on their extreme skate-track obstacle course, they inadvertently become a super hero known as The Beak! Isabella immediately starts investigating, and writes an article about the hero in the Fireside Girls Gazette. Things get crazy when a local super villain sees the article and declares war on the Beak! Meanwhile, Dr. Doofenshmirtz hatches his latest plan - he simply tells the citizens of the Tri-State Area that he's in charge, hoping they go along with it. And hey, where's Perry ?
