Ace: Hey! Let Perry go, Duck!

Ace bring out his Sword

Duck: What? You rather fight me? Over an Animal who doesn't have a Special Heart?

Ace: Special Heart or not. At least, at least he has a Family and friends.

Duck: Family and Friends?

Phineas and Ferb ran off to perry

Ace: You might not hear it. But now it's loud and clear, and it's telling that you're on a wrong side.

Duck: Then you leave me no choice.

Phineas: Perry! Are you okay?

He open his eye and he close

Phineas: Is he?

Ferb look down and then Perry wake up

Phineas: Wait? You trick us?

Perry Nod

Phineas: Oh, Perry.

Daffy: Run!

Ace: Duck! Duck, where are you?!
