Continuity mistake: Episode 66-5 "Hassle In The Castle/Remy Rides Again": In the final scene, notice the house across the street furthest to the left; first time it is shown there is a large window with light coming through. The last time we see the same shot, however, it is a totally different house.
Plot hole: Season 6, Episode 5 (overall episode 73) "The Good Ol' Days / Future Lost": In the episode "Future Lost", when Mark is hugged by several students at school, wouldn't he possibly freak out, since he is a Yugopotamian who doesn't like being hugged?
Continuity mistake: Episode 4-6 "The Jimmy Timmy Power Hour": In the scene where Timmy and Cindy are in the Candy Bar their milkshake has two straws for the first two shots. But in the next shot there's only one straw which is on Timmy's side, it then moves to Cindy's side. Then when Carl, Sheen, and Libby run in both straws appear again. When they all run out there's only one straw and on Timmy's side.
Continuity mistake: 5-59 Just Desserts. When Crocker jumps out of the open window in the classroom, notice on the exterior of the school all the windows are closed.
Continuity mistake: In the Fairly Oddparents episode "Power Pals", when one of the Power Pals chucks a crystal into a drain to create "The Table of Frienditude", the crystal bounces under a table and into a drain directly under said table. However, when the shot pans out, the drain is beside the table, not under it.
Factual error: In the episode Catman Meets The Crimson Chin., When Timmy guesses the password to release Cosmo and Wanda he types CAT notice that where he hits the keys are not in the right position for typing CAT.
Continuity mistake: In Mother Nature, when Timmy goes to apologize to his Mom, the two makeup guys dissapear after his mom notices him.
Continuity mistake: In "Oh brother!" after Timmy gets beat up by Francis, he is in his room with a lot of injuries, yet when he wishes for a new brother and his mom calls him for something, the injuries are gone.
Plot hole: In "Oh Brother!" Timmy wishes for a brother who will beat up Francis and some other things. How come he doesn't beat up Francis, even though Timmy wished for it?
Suggested correction: Remember that episode where Timmy tried to wish something bad would happen to chip skylark? Da Rulez say that you can't wish that someone could be injured/beaten/dead.
Continuity mistake: In the episode Miss Dimmesdale, in the scene where Vicky has Timmy pinned to a board in the garage. The next scene shows Adam West pulling Timmy in with a claw, notice that there is nothing in the garage but in the next shot a bunch of tools appear.
Continuity mistake: In the season 3 special "Fairy Idol", Norm looks at various newspaper clipping about how bad Bucky McBadBat is. One of them says "Worse Baseball Player Ever" when it should really be "Worst", and when Norm hands the paper to Chester later, it suddenly does say "Worst".
Factual error: When the characters in this cartoon are floating, the shadow circle on the ground is smaller when they are higher and bigger when they closer to the ground.
Continuity mistake: In "For Emergencies Only" were Timmy is in Mr. Crocker's classroom, the board says, 'Pop Quiz Today'. 'Today' is underlined. In the next shot, nothing is underlined. After those two shots, it is all underlined.
Father Time! / Apartnership! - S1-E4
Plot hole: Timmy uses his heat vision, that he previously wished for, to win the race for his future dad. But it's revealed later in "Smarty Pants" that if you use a previous wish in a contest, it is magically taken away because it's cheating.
Suggested correction: That is true, that rule was mentioned in a later episode. However in the episode Christmas Every Day, it was revealed that new rules could be added at anytime. So it's possible that the rule simply didn't exist yet. Although, this plot hole may apply to any episode released after "Smarty Pants."
Father Time! / Apartnership! - S1-E4
Continuity mistake: When an 'angry' Wanda throws a styrofoam picture of Cosmo and Wanda on the floor near Cosmo, it breaks, but some shot later, both pieces are gone.

Continuity mistake: When Cosmo and Wanda are saying what Vicky likes more than Timmy, their castle brick outline changes.
Chin Up! / Dog's Day Afternoon! - S1-E5
Continuity mistake: This mistake is found in the episode where Timmy wishes himself into the Crimson Chin's comic book after causing the Crimson Chin to become depressed. After defeating the Bronze Kneecap, the Crimson Chin are walking, and the Crimson Chin has no cape. When they appear before a large American flag, the Crimson Chin suddenly has a long, flowing, red cape flapping in the win. When they walk into the "letters to the editor" page, the Crimson Chin no longer has a cape.
Chin Up! / Dog's Day Afternoon! - S1-E5
Deliberate mistake: When Cleft (Timmy) and the Chin go to the last page with the letters and they get to Timmy's letter, Chin says he spelled Chin wrong yet you must see it's spelled right.
