This episodes' events runs concurrently with the plot of the following episode; "Isabella And the Temple of Sap".
Tropes:
- Celebration Miscalculation: Major Monogram and Carl drop balloons and swing rattles around to celebrate Agent P's birthday, then Monogram realizes it's not actually Perry's birthday.
- Brick Joke: At the beginning, Linda mentions that Lawrence told her that Candace is already good at parallel parking, a nod to "It's a Mud Mud Mud Mud World!". At the end, after Candace drives recklessly all over town trying to catch the boys, she slides the car in between two cars and Linda says "Well, guess your father was right. You do have parallel parking down."
- Did I Just Say That Out Loud?: Tough guy Buford expresses a desire to "float around like a little woodland pixie", then asks "Did I just say that out loud?"Phineas: Yes, yes you did.
- Drives Like Crazy: Candace drives fast and reckless while trying to catch the boys in the act. Part of it is due to Doof's jetpack accidentally getting attached to the bumper.
- Failed a Spot Check: When Candace and Linda miss the bubble after it leaves the park, neither of them even notice the machine right in front of them.
- Floating in a Bubble: The bubble machine allows the kids to ride in a bubble.
- Goofy Print Underwear: After his costume gets ripped off, Dr. Doofenshmirtz is left in nothing but boxer shorts with Perry's face on them.Doofenshmirtz: For your information, I had these WAY before I met you!
- Hollywood Tone-Deaf: Normally, Doof is a decent singer, but he invents the yodelinator to give him a more country voice.
- "I Can't Look!" Gesture: Linda covers her eyes in fright at Candace's driving when the car is launched into the sky to get a good view of the kids in the bubble; by the time the bubble is in view, Linda is still not peeking and refuses to do so until they're back on the ground.
- Mind-Control Music: Doofenshmirtz's Yodel-inator disguises his voice to sound smooth so he can hypnotize the audience into obeying him with his song.
- Non-Singing Voice: In-Universe. Normally, Dan Povenmire does his own singing as Doofenshmirtz, but the yodelinator gives him a more country-western voice sung by Jeff Gunn... until Perry kicks his hat off.
- Schedule Fanatic: Baljeet becomes one of these during this episode, having a schedule so tight he has to pencil in answering a question. He's also put Phineas asking "Where's Perry?" right on time.
- Synchronous Episodes: This episode is synchronous with "Isabella And the Temple of Sap".
- Third-Person Person: Baljeet mutters to himself, "No one wants to ask Baljeet what he is doing."
- Uncomfortable Elevator Moment: Perry shares the elevator to his lair with Pinky.
- What Happened to the Mouse?: Though the bubble does pop at the end, it is not explained what happened to the machine that made it.
