What Season 4 of Phineas and Ferb
Phineas and Ferb spend another summer in Danville and, as always, take on impossible projects for two kids. This season they build a dental amusement park, an obstacle course, and a climbing wall. Candace is still determined to catch them so their mom will punish them, though she almost never finds proof. Perry the Platypus, meanwhile, once again foils Doofenshmirtz, who goes from turning into a hairy monster to trying to take over the Tri-State Area. Candace's schemes with Jeremy and the jobs Isabella and the Fireside Girls give them round out the 26 episodes.
