Top 10 Cartoon Mistakes Spotted By The Fans

“Teenage Mutant Ninja Turtles” (1987-96)
What’s better than one Michelangelo? Well, how about two! In the episode, “Turtles of the Jungle,” the ninja reptiles have to deal with Professor Willard W. Willard’s Molecular Intensifier. He ends up accidentally using the device on his pet monkey Jocko. After the primate grows huge, the turtles try to stop the big ape from destroying the city by leaving onto his leg. When the giant ape removes Michelangelo, the turtle somehow manages to leaves a copy of himself on Jocko’s leg. We don’t remember the professor's machine also having the ability to create clones of the heroes.

“What's New, Scooby-Doo?” (2002-06)
In “Ready to Scare”, the gang helps Daphne figure out what happens to her cousin in Paris, France. They eventually end up following a suspicious trail on the street towards the sewers. When Fred, Velma, and Daphne go into the gross muck, they decide to change shoes. But it's much easier for one member of the trio. Without warning, a small wall that’s perfect for perching on when changing footwear magically appears despite not being in any previous shots. The red-headed sleuth soon uses it to sit on and change. While it’s great for Daphne, it's pretty awkward that Parisians now have to deal with a random magic wall in the street.

“The Adventures of Super Mario Bros. 3” (1990)
During its brief one season run, this plumber themed show became known for its trippy and often inconsistent animation. It all got off to a rough start with the “Sneaky Lying Cheating Giant Ninja Koopas,” pilot episode. At different points, Luigi’s color palette switches between his traditional green to Mario’s red. (Xref) Another Nintendo property that got a show with an awkward pilot was “The Legend of Zelda.” The episode “The Ringer” has a trap door that keeps changing position in Link’s bedroom. One moment it’s to the side, then it’s suddenly in the middle of the room. We hope the hero of Hyrule doesn’t fall in because the door moves so much.

“Invader Zim” (2001-06)
Dib and Gaz don’t exactly have a close or stable sibling relationship in “Invader Zim.” If they’re not setting creepy security robots to go after the other, they might be practicing magic on each other. In the episode “Gaz, Taster of Pork,” a spell Dib casts makes his sister only able to taste pork in every food. After she threatens him to fix it, the two walk back to their house to see their father Professor Membrane. But the two oddly appear to be holding hands on their walk there. Anyone who’s familiar with their tension filled relationship would know that they would never get that close. According to reports, the show’s creator Jhonen Vasquez admitted it was an animation mistake.

“All Grown Up!” (2003-08)
When our favorite toddlers turn into preteens, they have to deal with more complex issues than they’re used to. In the "Thief Encounter" episode, Tommy has been coping really badly with studying with some big exams. The stress even causes him to sleep-steal from his neighbors’ gardens. But that problem also leads to a big issue with continuity. At the start of the episode, Betty DeVille asks Dil and Tommy if they’ve seen her missing garden gnome, Rufus. That implied that Tommy had already started his sleep thieving. But he didn't find out about the exam that would’ve caused this bad habit until after the opening. If the writers didn’t mess up, Betty has to worry about a thief that looks just like Tommy.

“Dexter's Laboratory” (1996-2003)
Have you ever become so impressed watching musicians perform that you’ve flown off into the sky? Apparently, that unlikely event can happen in the world’s “Dexter's Laboratory.” The segment “Chubby Cheese” features a performance set at a kids oriented restaurant. When the number finishes, a large portion of the audience applauds and suddenly flies off. We assume they returned to their home planet like Poochie in “The Simpsons.” Apparently, this error happened due to a miscommunication between the storyboard artists for “Dexter's Laboratory” and the Korean animators. The storyboard said the audience was meant to “take off” as in "leave" after the performance, but the artists interrupted it as "flying." This miscommunication led to a hilarious Chubby Cheese mistake.

“Bob's Burgers” (2011-)
While celebrating Thanksgiving in the episode “Dawn of the Peck,” Linda and the kids go off to the “Turk-tacular Turkey Town Festival.” One event features the “Turkey Trot,” which is similar to Spain’s Running of the Bulls, just with the feathered creatures instead. But it all goes sideways fast. Mr. Fischoeder and his equally eccentric brother Felix soon start running with the crowd to escape the birds. Although they think they’re in major trouble, it’s nothing compared to a person in a crowd that is much closer to a turkey than he should be. The fowl appears to be coming out of a portal in the man’s face. It turns out that it’s not even safe to be a spectator for this thanksgiving event.

“SpongeBob SquarePants” (1999-)
After Spongebob upsets his neighbor, he spirals and starts believing that he’s abnormal. In order to address this issue, he gets a video called “How To Be Normal For Beginners” to learn how to fit in. But when SpongeBob looks at the cover, he’s missing his right arm! (Xref) This actually seems to be a regular problem for SpongeBob. After visiting “Glove World” in the “Rock Bottom” episode, he somehow gets his glove hat behind his eyes. When SpongeBob goes to get on the bus, his left arm has disappeared before it reappears as he starts walking. This is really al-arm-ing!..yeah, we regret that.

“The Fairly OddParents” (2001-17)
Ever since Doc and Marty time traveled during the 1985-set “Back to the Future”, many properties have referenced the movie. “The Fairly OddParents” episode “The Secret Origin of Denzel Crocker!” is no exception. As Timmy, Wanda, and Cosmo use the Time Scooter to look into Crocker’s past, they eventually go to Dimmsdale University. They even see the iconic DeLorean take off. However, Timmy traveled back to 1982. That was three years before Doc got the DeLorean working. Admittedly, Marty and the Doc could’ve easily had other time shenanigans that we didn’t see in the movie trilogy. But we’re guessing the show really wanted to make the reference and ignored that the dates don’t match up.

“The Simpsons” (1989-)
Animating musical instruments is really hard. You have to match the sound to how it's played, which takes so much effort. Thanks to the YouTube channel “Amosdoll Music”, we know a few piano scenes in “The Simpsons” don't measure up. Firstly, in the episode “Lisa vs. Malibu Stacy,” Homer plays with the giant stepping keyboard in a store. Amosdoll Muisc plays the notes Homer touches and shows the sound he produces is vastly different from what we hear. Additionally, in “Bart Sells His Soul,” the church’s organist is tricked into performing “In-A-Gadda-Da-Vida” by Iron Butterfly. But the notes she touches don't match at all. We guess everyone in Springfield needs more piano lessons.
