- Dr. Heinz Doofenshmirtz: [as Dr. Jekyll after transforming into a pixie] You know, in hindsight, I regret even including a fairy princess dial. But you know, live and learn.
- Dr. Heinz Doofenshmirtz: [as Dr. Jekyll while franken-Perry is punching him] Wait, wait. Time out. Allow me one little drink before we continue. I-I'm parched.
- Grandpa Reg: [finishing his story] And that is why there are pumpkins.
- Phineas: Um, Grandpa, you were telling us about a platypus monster.
- Grandpa Reg: Ooh, that sounds very exciting, tell me about that.
- Phineas: But you were... I mean... I didn't...
- [sighs]
- Phineas: I got nothin'. Ferb?
- Ferb: Platypus monsters are the only monsters to lay eggs.
- Phineas: [looking at the rain outside] Looks like a real summer storm. Well, our plan to stand alone in the middle of a field with a metal rod is out.
- Candace: [as Constance, going to down to the lab] What is going on down there? I will go straight to the angry mob and tell on you.
- [throws open the lab door]
- Candace: Ah ha!
- Phineas: [as Dr. Phineastein] Oh hi, Constance. We're gonna enter the best monster contest.
- Candace: How are you going to enter the monster contest? You don't even have a monster.
- Phineas: [after franken-Perry leaves the castle] Oh great! We really have to stop losing our monsters.
- Isabella: [seeing Dr. Phineastein and Ferbgor] What'cha doin'?
- Phineas: We're looking for a giant platypus monster. Have you seen one, by any chance?
- Isabella: Funny you should ask. We spent the entire afternoon together. We went swimming, had a little lunch. Did you know he eats raw snails?
- [shudders]
- Isabella: Ew! I stuck to PB&J on whole wheat.
