!!Tropes
* AdvertisedExtra: Despite the title, this episode has barely anything to do with Candace. It was most likely chosen for being a pun on "oil on canvas".
* ADayInTheLimelight: Django gets an increased focus during this episode.
* BorrowedCatchphrase:
** Dr. Gevaarlijk, upon seeing Perry, says, "He's just a platypus. They don't do much, y'know."
** At the end, Doof says, "Oh, there you are, Perry the Platypus."
* ChorusGirls: This marks the first appearance of Doof's union chorus girls. After the song, he has to pay them, and he even attempts to ask one out, but to no avail.
* ContinuityNod: Doof shows Dr. Gevaarlijk many past inators including the [[Recap/PhineasAndFerbTheFastAndThePhineas the Deflatinator ray]], [[Recap/PhineasAndFerbAreYouMyMummy the Woodenator]], [[Recap/PhineasAndFerbSWinter the Meltinator 6-5000]], [[Recap/PhineasAndFerbCandaceLosesHerHead the Drillinator]], and Phineas and Ferb's [[Recap/PhineasAndFerbIScreamYouScream ice cream sundae maker]] that he made by mistake.
* DeadpanSnarker: Dr. Gevaarlijk is so disappointed in her past student that pretty much every other line is this.
* FreezeFrameBonus: Doofenshmirtz has a tiny gnome in his house plant.
* InformedFlaw: Doofenshmirtz is showing off his career of evil to his old teacher. When asked whether his -inators actually worked, Doof sheepishly "admits" that they didn't, even though anyone who watched the episodes they appeared in would know that they actually worked just fine. The only part of that sequence that was accurate was that the Drillinator did indeed fail to harm anyone other than Doofenshmirtz himself.
* IWantSong: "Impress My Professor", sung by Doofenshmirtz as he wants to impress Dr. Gevaarlijk with his inators.
* TheNapoleon: Dr. Gevaarlijk is practically half the size of Doofenshmirtz. Lampshaded upon her arrival when she sarcastically comments on how big he has gotten.
* OpeningShoutOut: The giant paint rollers are similar to the ones shown during the "Painting a continent" part of the theme.
* PulledFromYourDayOff: Perry is at home enjoying his soaps, but unfortunately, Monogram interrupts them by giving him a mission. Thankfully, Monogram already taped his soaps for him.
* RuleOfThree:
-->'''Candace''': Mom! Mom! Mom!
-->'''Django''': Dad! Dad! Dad!
-->'''Doofenshmirtz''': ''Doktor! Doktor! Doktor!'' Oh, sorry, I didn't mean to shout.
* SpoofAesop: Dr. Gevaarlijk at first very genuinely tells Doofenshmirtz that he can spread evil in the little things he does, but then says he can't even do ''that'' because of his ineptitude.
-->'''Dr. Gevaarlijk''': You're a total failure! You sicken me, Heinz Doofenshmirtz! Gevaarlijk out!
* SubvertedCatchPhrase: When Perry assures him he's a worthy evil nemesis, Dr. Doofenshmirtz says "Thank you, Perry the Platypus," instead of "Curse you, Perry the Platypus!"
* TitleThemeDrop: The scene where the boys and Django paint the Unpainted Desert is accompanied by an instrumental version of the theme song.
