Background Information

 * First announced at San Diego Comic-Con 2017, and confirmed by The Hollywood Reporter.
 * There have been many Phineas and Ferb Easter eggs in Milo Murphy's Law to lead up to this crossover.
 * This is the first episode of the second season of Milo Murphy's Law.
 * It is revealed that Baljeet and Buford are fans of The Lumberzacks, and that Baljeet carries their CD with him all the time.
 * Isabella has only two lines in the entire crossover.

Production Information

 * Due to Thomas Sangster's schedule conflicts with filming Maze Runner: The Death Cure and other projects, the role of Ferb was recast in this episode with David Errigo Jr.

International Premieres

 * Japan: August 10, 2018

Errors

 * Doofenshmirtz isn't the first to invent time travel, since Phineas and Ferb fixed the time machine in the museum in the episodes "It's About Time!" and "Phineas and Ferb's Quantum Boogaloo". But Doof probably wasn't aware of that.
 * When Phineas, Ferb and Milo strap on their seatbelts in the robot, Ferb's larger eye is facing the audience.

Continuity

 * This episode will be a continuation of the Milo episode "Fungus Among Us".
 * When Doof changes the channel, Katt Karr, Ducky Momo, The Klimpaloon and the Giant Floating Baby Head Hour, Horse in a Bookcase, and Dancing with the Bears from Ferb TV can be seen.
 * Phineas mentions the satellite they built that was in Phineas and Ferb: Mission Marvel.
 * Doof once again mentions Pizzazium Infinionite. (Vanessassary Roughness, Mission Marvel)
 * Doof, Perry, Orton, Dakota and Cavendish end up on the Island of Lost Dakotas.
 * Milo offers Phineas a blowtorch and some peanut butter, a reference to Rollercoaster.
 * Professor Time's time machine looks very similar to the one featured in It's About Time! and Phineas and Ferb's Quantum Boogaloo.

Allusions

 * Batman - When Milo, Agent P and Diogee head back to Milo's house, a transition not unlike the "Bat-transitions" from this 1960s campy TV series appears.
 * Pokémon Go! - Candace plays Ducky Mo-Go, an app that essentially parodies this fad revival augmented reality app.
 * Futurama - One of the pistachions call the humans "meatbags", just like Bender.
 * The Exorcist - Doof says, "The power of orange soda repels you!" three times, a reference to Father Merrin and Father Karras' repeated line "The power of Christ compels you!" from the 1973 film.

Trivia

 * Many Phineas Easter eggs have been sprinkled throughout Milo Murphy's Law to lead up to this episode, cluing to the fact that both Milo and Phineas share the same universe.
 * This will be the third crossover for Phineas and Ferb. ("Phineas and Ferb: Mission Marvel", "Phineas and Ferb: Star Wars")
 * Phineas and Ferb interact with Doofenshmirtz for the third time. ("Phineas and Ferb The Movie: Across the Second Dimension", "Night of the Living Pharmacists")
 * Candace doesn't try to bust the boys once again.
 * Running gag: Everyone seems to think that Zack and Melissa are a couple. (Yeah, but a couple of what?)
 * Running gag: Buford explaining the joke, much to Baljeet's chagrin.
