'Disney XD Presents' A black and white image of a street in Danville turns to colour. [Quiet, Creepy Music] Cut to Phineas on a branch in the biggest tree in Danville. Irving is at the bottom of the tree.
Phineas: You are just in time for the best part of the day!
Irving: What part is that?
Phineas: The part where you and me...
He slides down the tree and into Irving.
Phineas: ...Become 'we'.
'A Timeless Friendship...'
Phineas bends forward on a raft with his arms spread out and Irving holds Phineas's waist (Which is obviously a parody of 'The Titanic'). Cut to Phineas leaping into a pile of leaves under the tree in their backyard, only to land on a small tool box which has a note on the lid. He opens the tool box and the note splashes into a mud puddle.
'Nearly Comes To An End...'
In Danville Park, Phineas looks around the biggest tree, anxiously.
Phineas: Irving? Are you here? Are you there? Are you anywhere?
Cut to Ferb clinging onto a snapping branch on the tree in the Flynn-Fletcher Bakyard, while covering his eyes.
