Meanwhile, Phineas and Ferb build a rock climbing wall, Linda tries to spot a rare bird, and Candace loses her voice when doing a lengthy amount of recordings.
Tropes:
- Bait-and-Switch Comment: Candace sounds like she's doing vocal warmups before starting the book narration, but it's the actual book's dedication page.
- Batman Can Breathe in Space: Phineas and the gang leave the Earth's atmosphere at the top of the rock climbing wall and don't wear space suits, causing the lack of oxygen to make them delirious.
- Bigger on the Inside: Perry's gingerbread house trap is this, which Doof lampshades.

Irving: You drive a hard bargain, I'm in.
Isabella: It's okay. I was about to ask that anyway. - Chekhov's Gunman: The bent-bill nuthatch.

- I Am Very British: Both Lawrence and Ferb exhibit British stereotypes.Ferb: Some tea with honey will help with that throat. And there's crumpets in the conservatory as well.Candace: He's so British.
- Lost Voice Plot: Because of the amount of time spent recording the audiobook of the Fireside Girls handbook, Candace ends up losing her voice, and can't even yell for her mom to bust her brothers.
- Metaphorgotten: Doof remarks that he is most likely grasping at straws with his latest scheme.Doofenshmirtz: I'll probably end up grasping at bendy straws and fall on my face requiring months of rehab and have to learn how to monologue all over again...

- Shout-Out: Buford screamed in space to see if anyone could hear him. He heard it.
- Sugar Causes Hyperactivity: Doof and Perry end up eating so much dessert that they jump up and down and up and down a lot. They later suffer from a sugar crash, but Perry fixes his sugar crash by eating some protein and carbohydrates from his hat.
