Specials[]
| Episode | Image | Big Idea | Notes |
| "Camp Rock 2: The Final Jam" |

Background Information[]
- The plans the boys come up with can be described as impossible because they are accomplished in a very short amount of time (less than a morning {they use the invention in the afternoon, most likely}) and involve technology that has yet to exist in the real world: teleportation, mind-switching, time traveling... Phineas and Ferb do not think of their plans as impossible, just fun and great. When Isabella asks Phineas if building a time machine is "kind of impossible", he replies, "That's a possibility". ("It's About Time!")
- The phrase "Big Ideas" references the advertising campaign that Disney Channel ran prior to the launch of the series in February 2008. For Phineas, it was "he thinks big". For Ferb, it was "he thinks how".
- Despite Phineas saying that he likes to "keep moving forward", he actully has repeated his big ideas. Examples are the waterslide in "Leave the Busting to Us!" and "Elementary, My Dear Stacy" and the time machine in "It's About Time!" and "Phineas and Ferb's Quantum Boogaloo."
- Phineas and Ferb have been busted eight times on-screen, although the first time ("Phineas and Ferb Get Busted") it was all Candace's dream in Perry's dream. The second time ("Interview With a Platypus") mom saw the animal translator, only to her Phineas and Ferb were just using some sort of recording machine. The third time occurred in the episode "Thaddeus and Thor", when their mom saw only the top portion of the fort (and not the other giant parts of it). Upon seeing this, she remarks on how Phineas and Ferb are "beginning to take an interest in building things." The fourth time ("The Lake Nose Monster") their mom actually sees the small boat which they built (Nosebud) and says that it's "pretty cool" because it actually floats. The fifth and sixth time ("Phineas and Ferb's Quantum Boogaloo) it both happened in a different universe. The fifth time older Candace busted them while building the Rollercoaster, which has been undone by herself after she saw that this would lead to a dystopian society run by Emperor Doofenshmirtz. The sixth time Candace busted them by showing herself to future mom, but this has probably been undone by Isabella when she went back in time and made the entire episode undone. The seventh time ("The Bully Code") mom saw Phineas and Ferb's creation, only Phineas and Ferb were gone and she thought it was some kind of modern art. The eighth time was when they built a pioneer village in "She's the Mayor", but that was undone when the acceleratorinator moves time backwards. Note: there are other times where Phineas and Ferb's plots have been seen by their parents, a famous example being in "Dude, We're Getting the Band Back Together" among others, however they weren't "busted" for them (assuming "busting" implies that they were intentioned to get in trouble for whatever they're doing). Also, all times Phineas and Ferb have been busted happened in Season 2.
