104 Days of Summer Vacation… Extended! Phineas and Ferb Return Summer 2025
You know the theme song: “There’s 104 days of summer vacation…” But what happens when summer gets extended? For Phineas and Ferb fans, it means new adventures, catchy songs, and epic fun! Dan Povenmire and Jeff “Swampy” Marsh, co-creators of the beloved series, are back with Season 5, set to debut in Summer 2025 on Disney Channel and Disney+.
“Since Phineas and Ferb is essentially a celebration of summer vacation, summer is the perfect time to debut the new season,” the executive producers said in a recent statement to Variety. “We have had such a great time diving back into this world and the entire cast and crew have really brought their A-game. We cannot wait to see fans’ reactions to what is shaping up to be our favorite season yet.”
A New Summer, A New Beginning
This new season is not just a continuation—it’s a whole new summer! Set one year after the events of Phineas and Ferb: The Last Day of Summer, Season 5 kicks off with a splashy musical number celebrating the start of a brand-new summer vacation. “We wanted it to feel like the same show,” Dan shared, “but with the excitement of a fresh start for all the characters.”
Fans can expect the same blend of creative storytelling, over-the-top inventions, and hilarious humor that made the original series a hit. And, of course, Perry the Platypus is back for more secret-agent adventures!
What to Expect in Season 5
While Dan and Swampy are keeping most details under wraps, here’s what we know:
- Returning Favorites: Phineas, Ferb, Candace, Perry, and Dr. Doofenshmirtz are all back. Expect sibling rivalries, wild inventions, and secret missions.

The Return We’ve All Been Waiting For
After 222 episodes, five hour-long specials, and two feature films, the love for Phineas and Ferb never faded. Dan and Swampy were initially concerned about generating fresh ideas for the new season. However, just one week into working in the writer’s room with returning and new writers, those fears disappeared. In fact, Dan believes at least seven of the new episodes are destined to become instant fan favorites.
