The Grim Adventures of Phineas and Ferb

A combination between Phineas and Ferb and The Grim Adventures of Billy and Mandy.

Story
It's "Moms Take They're Kids to Work Day", so at the Danville Curio Shop, Candace is bored out of her gored. Phineas and Ferb soon find panphlets for a summer camp, so Phineas goes to ask they're mom if they can go. But Ferb gets distracted by Vanessa and grabs the wrong panphlets. Isabella, Candace, Buford, and Baljeet also go along for the ride. But when they exit the bus, they wind up in Endsville and meet Billy, Mandy, Irwin, and the Grim Reaper. But when Buford and Baljeet accidently release the Endsvillains, they must split up into teams to stop them! Meanwhile, Perry must stop Doofenshmirtz from using the Blue Ruby in his Dogcontrolinator.
