Revealing mistake: When we first see Yosemite Sam at the tiller at the beginning of the cartoon, he moves the wheel back and forth but the capstan and rope do not move even though they are meant to be attached to the wheel.
Revealing mistake: When we Yosemite Sam holding on to a branch on the tree after the explosion, some of the apples are being held on to the branches without their stalks.
Revealing mistake: When the traveller crosses the drawbridge towards the end of the cartoon, the edge of the cel is visible.
Revealing mistake: When Branch first takes Poppy into his bunker, and down into his storeroom, the lever that he uses isn't there, but when the shot goes to Poppy, and then returns to Branch, the lever is magically there.
Revealing mistake: During the final race, Wrangler is shown knocking a yellow car off the race course. A few seconds before this, there are two shots from behind Wrangler, that are just still frames. The shot does not show Wrangler driving or even moving and is completely still. The shot from behind is merely just a still image, that has been extended to last a split second. The same still frame image is also repeated two shots later. (00:27:35)
Revealing mistake: When Jerry walks towards the crab with the soda bottle cap stuck on his head, one of the crab's legs disappears for a frame or two.
Revealing mistake: When the Level 3 Sentry is firing up into the air for no apparent reason, it fires some rockets with a clear defined smoke trail behind them and disappear off screen. Then the shot jump cuts to further away and suddenly the smoke appears again, but the end of the smoke trails are solid and crisp indicating the animators used the smoke animation as if the rockets had just been fired from that spot... in the middle of the sky. (00:01:10)
Revealing mistake: After Robin starts to believe that the Teen Titans are in fact a joke, he gets sad and goes out a hole in the wall saying goodbye to them. He fires his grappling gun up and steps out of the wall. But his arm remains bent as he stands casually in the air to be taken upwards. There is no effect of gravity or any realistic body motion in those moment. As his weight should have had him dangle down with his arm stretched out above him and him swaying like a pendulum. Instead he appears as a stationary action figure in a single pose with his elbow bent as he's taken up.
Revealing mistake: When The Ray lands on the ground regrouping with the other Freedom Fighters, there is a bridge behind him with many civilians walking in the background. The animators took an obvious shortcut here as the civilians in the background just consist of the sprites of about 5-7 different people just repeated over and over again all in their same poses on each copy as they move. One especially noticeable one is a kid walking in an olive gray shirt with his arms up right next to himself over and over again. (00:01:45)
Revealing mistake: When Sal is eating the leaf, nothing is ever shown breaking off it or going into his mouth. It just appears to remain intact whilst eating it. (00:08:10)
Revealing mistake: After successful surgery, Bruce's friend shows him the first page of a newspaper with the headline about the news, "The National Whisper." The 'date' is "November 2016", which is a bit odd (a monthly newspaper?), but even better is the fact that it just sports obvious gibberish all over. The title of the boxed article is "Geiare la goer uoa oge ou osgeou osd ogoernis pgoer aoubepre obieri ai beiragoer." (00:17:15)
Revealing mistake: In the Arena Challenge scene, the statue of Toa Lhikan falls on the herd of Vahki and part of the statue's mask is going through the ground. (00:22:30)
Revealing mistake: This happens in the second ceremony when Wolf didn't press the button to shut off the lights to steal the golden dolphin because of the good comments. Few seconds later, the lights shut off, and you can see that the meteor on the top disappears at the time.
Revealing mistake: When displaying the information of Ash, Pikachu, Tory, and Torkoal, the information is filler text. (00:22:54)
Revealing mistake: When Umi is first descending the stairs in her house, her left hand clips through the left railing.
Revealing mistake: When Mole is fleeing with the deed, he runs down a hallway and crashes into what appears to be a mirror. However, his reflection is missing from the mirror before he hits it, revealing it's not behaving like a real mirror. (00:32:05)
Revealing mistake: In the POV shot from Thomas, capturing Bill and Ben puffing away from the water tower, Thomas seems to be off-centered from the tracks, making it seem like he is derailed.
Revealing mistake: In many shots where Ryan is live streaming his magic show, Aiden's phone screen reveals she is actually recording in the iPhone Camera app. (00:01:17)
Revealing mistake: When Persephone is brought to her throne, she takes a bow. Watch the fawn next to the throne; in that moment, for a few frames, one of his legs disappears. And there's an animation glitch where a white line shaped like his leg appears on his body, then flickers up for about 3 or 4 frames before his leg returns to normal. (00:01:10)
Revealing mistake: When Pegasus sees Kaiba in the reflection of his wine glass, Kaiba's hair is not mirrored, which it should have done since it was a reflection. (00:13:23)
