Other mistake: In the scene where Yakko, Wakko and Dot are sitting at their desks repeating Miss Flamiel's every word, Wakko is drawn without legs (only feet) during one shot.
Monkey Fun - S2-E13
Other mistake: Season 2 episode 13 "Monkey Fun": Just before the enlarged Titano appears at the zoo, there is a family watching normal-sized monkeys in a cage. The family father (farthest on the right) has a drawing disorder with his eyes: their pupils look up and down, respectively, giving him a rather goofy expression.
Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
Injustice For All (2) - S1-E19
Other mistake: Unless he escaped prison, it makes no sense for Copperhead to be in the police van with the other Secret Society members. You can see him sitting there across from Solomon Grundy and The Shade.
Other mistake: At Honker Burger, when Skeeter introduces Doug to Patti, the lower half of Doug's body and both of his arms are missing; the animation is incomplete. (00:20:55)
Other mistake: Kendra slaps the right side of Donna's face to stop her from freaking out. Donna then rubs the left side of the her face. (00:14:05)
Moero! Pegasus Ryuseiken - S1-E2
Other mistake: In the ending shot of the tournament bracket showing the potential future opponents, the two saints' names are written the wrong way, as "DORAGON" and "ANDOROMEDA", instead of Dragon and Andromeda. (00:22:00)
The Origin of the Fantastic Four: Part 1 - S1-E1
Other mistake: When Puppet Master is making a clay figurine of Thing, the mold he uses doesn't have a Thing-shaped interior with which to make a detailed figurine. The figurine should have just looked like an undefined human-shaped figure. (00:15:20)
Other mistake: In the scene where Raphael and Michelangelo report from their ceiling vantage point, we see a hallway full of Foot ninjas. Strangely, we can see a brief shot of an Earth Protection Force trooper walking peacefully among amongst the Foot even though they are hostile to them. (00:07:50)
Other mistake: While Sonic and Tails are locked up in old Spelunk's cage during the cave-in, right before the huge diamondius crashes on top of the cage, there's a close-up of Sonic holding the bars, and the color of his torso becomes the same as the background mid-shot.
Other mistake: In the English dub of the series, Tai's last name is Kamiya; however, when he makes reference to the family name plate his father put on the front door in this episode, the name displayed is Yagami. (00:03:00)
Is Lupin Burning... ?! - S1-E1
Other mistake: The logo of the evil organization, Scorpion, contains just a little misspelling. It's missing the R. (00:02:50)
Cold Spells - S1-E2
Other mistake: After Ganon zaps Spryte with a spell to make her spells go crazy, he begins laughing. Watch closely at this point. Just above his hand, the only one visible at this time, a random black line like thing just appears and begins moving up. It has a couple spasms in its movement as well. I cannot tell what it is, and it is definitely not a bug. Whatever it is, it's not supposed to be there. (00:20:20)
Blue Wants to Play a Game - S1-E12
Other mistake: The jigsaw puzzle Steve and Blue help Shovel and Pail with has a picture of everyone playing musical chairs from the Mailbox's Birthday episode, but Steve suddenly isn't in the puzzle. He played musical chairs, so he should've been in the puzzle.
Vampire Bats and Scaredy Cats - S2-E2
Other mistake: When the Mystery Company find a torn paper in a coffin, it is written exo-6 and something else. They find later that exo is the first part of exotic. The way the paper was torn, you should be able to see the lower part of the missing letters.
To Touch a Hummingbird - S2-E10
Other mistake: Chris gets on the zip line and hooks up. Martin just stands behind him, not hooked up to the zip line. Chris zooms off down the line chasing the hummingbird. A few seconds later, Martin is suddenly on the zip line also and right behind Chris.
Coffee Quest/Phoenix Rises - S1-E18
Other mistake: In Phoenix Rises, when Phoenix runs away, the Big Coffee sign is missing.
What If... Captain Carter Were the First Avenger? - S1-E1
Other mistake: The premise of the first episode is flawed; "a single choice" should make the difference, the choice being identified as Ms. Carter not leaving the room to get in the observation booth. But in the normal timeline the booth is exactly where all the other characters were. In this reality everyone else is downstairs, with the German spy that inexplicably sets the bomb early. If anything, it's his bizarre, suicidal choice that matters.
Suggested correction: Except it was her decision to not leave the room that delayed the procedure and gave Heinz Kruger the chance to attack. And with her in the room, she is now given the chance to volunteer to take the serum.
How did her staying delay the procedure? Besides, in OTL the spy only triggered the bomb after he saw the procedure succeed, to know it works before stealing it.
Other mistake: When Viper slides the swords to Jackie and they come to a rest next to him, there is a small paper spider right beside Jackie. The only paper spider in the room, however, is Origami himself, and he is actually too far away at that moment and too big to fit the bill. Guess some of the animators got their depth perception messed up.
The Pyramid of Darkness: Part 1 - The Further Adventures of G.I. Joe - S1-E1
Other mistake: Mutt reads the card about the "fatal fluffies." He says "I'm sure you'll enjoy their deadly secrets", but the card reads "I'm sure you'll enjoy their amazing "split" personalities."
