Phineas and Ferb When Worlds Collide & Road to Danville (2007–2015) watch online HD

In "When Worlds Collide:" Phineas and Ferb hold a sleepover so they can check out their space probe. Buford's dubious past encounter with an alien "whalemingo" gets verified when the group discovers the creature's home planet. Unfortunately, earlier that day, Doofenshmirtz' Sphere Attract-inator inadvertently pulled it from its orbit, hurtling it toward Earth. In "Road to Danville:" Perry and Doofenshmirtz become road buddies of a sort then they have to hoof it back to civilization after the latest inator zaps them both into the heart of the nearest desert.
