In "Mommy Can You Hear Me?:" A broken leg restricts Candace to her bed while the boys make a backyard Stratospheric Ionizer to great an astronaut. With deli meats loading up his loft, Doofenshmirz launches into a food fight against Perry. In "Road Trip:" Phineas and Ferb enjoy the last day of a family road trip until they realize they haven't yet visited a classic, all-American roadside truck stop diner, so they build one - atop Dad's rented and in-motion RV.
