Used Car/Bounty Hunters - S8-E9
Continuity mistake: In "Used Car", when Beavis and Butt-head first approach the car, it's in between two trucks, a white one and a brown one. At the end, the spot where the car was is now between a green car and the white truck.
Factual error: The forces of Cassiopeia all sport the crown-like "W" sign which is the shape of that constellation... but only as seen from earth! These five points in three-dimensional space (like all star signs named after anything) look like that when viewed from our own planet; but from anywhere else, they aren't shaped like that at all. Why would they chose to see themselves through a very specific angle of view from some other distant planet (earth)?
Beyond the Farthest Star - S1-E1
Other mistake: When showing Scotty on the bridge, some of the frames show more of his body than others. In those frames, you can see that he lacks legs.
Snow Place to Go/Dunce Upon a Time/Gems the Breaks - S2-E4
Continuity mistake: Dunce Upon a Time: Lifty and Shifty give Nutty six beans, which are coloured blue, red, pink, yellow, orange, and purple. When Nutty shows the beans to Giggles, the yellow bean has been replaced with a green one. (00:08:22)
Race to the Spaceship/Sandbox Surprise - S3-E5
Revealing mistake: In the sequence where Pig is making a pizza with strange toppings, an ant caries a large bucket of popcorn up the counter. It is flush on its back with no top when on the floor, and the popcorn is bulging out. The ant turns 90 degrees and walks up the counter, and the popcorn thus turns on its side in the air. Not one piece of popcorn falls out or even shifts, despite the pile now pointing out rather than up.
Members Only - S1-E2
Continuity mistake: In the last scene, when Daffy and Bugs are talking to each other, Daffy's towel is yellow and in the next shot, it's white.
Continuity mistake: When Elizabeth starts weeping, her bodysuit is torn above her left breast with a single tear. Post-credits Meliodas asks her to join him; now that torn spot is split in two - the first time the bit of fabric that separates the two spaces was already severed. (00:17:40 - 00:22:30)
Continuity mistake: In the last classroom scene, the blue oval design on Gabby's cap appears and disappears between a few of the last shots of the scene, first when Vinnie runs up to Professor Q (because Rocket went ahead and switched both his and Gabby's test papers) and later when Professor Q was talking about how he was ∞ proud of Vinnie. (00:10:10)
Continuity mistake: In the opening credits, as the room becomes animated, Ricky has a coffee mug an inch away from him. The mug moves a good 10 inches away from Ricky the shot after Karl says "All right?" (00:00:35)
Other mistake: You don't have to look further than the name; the title of the series is "Knight's and Magic" instead of "Knights and Magic".
Ryuusui, Chimaera no Otoko - S1-E1
Continuity mistake: When Crosswords has the first attack of Chimera witnessed by Black Jack, his wife Sayuri runs to the fridge to grab the bottles. In the shot with the camera inside the fridge, there is a full complement of bottles in the bottom shelf, but in the other angle the right half of the shelf is occupied by glasses only. (00:09:15)
A Day in the Life of Retsuko - S1-E1
Continuity mistake: After Ton bashes Retsuko for not getting her tea right, she sings some death metal in the bathroom before joining Fenneko back at the computers and they start talking. Between them is a pink cup with some orange scissors, and an assortment of writing utensils. They are fanned out, but show that the red one is closed to Retsuko with the black in the middle and the yellow closer to Fenneko. When the camera changes angles to show them both sitting there, this order of pens is flipped, with the scissors still being in the same spot.
Surf'N Turf/Hardcase Returns - S1-E8
Revealing mistake: In "Hardcase Returns" Skidmark uses a digital phone to track a GPS device installed on Turbo's parade car. When the keypad on it is shown, 3 letters are missing. They could have been on the keys that had nothing written on them, but we will never know for sure because nothing is on them.
Continuity mistake: As Rey tells BB-8 that he can stay with her, you see the droid behind her from a frontal view. When it cuts to a side angle of BB-8, the lines and details on the side of it's head close to it's "eye" change with more lines appearing, the orange rectangles at the bottom become taller, and the white rectangle box moves higher up. Also in the side view there is some black cone sticking out of what would be BB-8's "face." If it's his eye it's now suddenly sticking out way too far and isn't that extended. If it's the little censor thing that is next to his eye then it's now on the wrong side of his head. (00:00:25)
Continuity mistake: In the close-up of putting the lids on the bottles, Mat's hands have 5 fingers (briefly done by a real person instead of the puppets). However, throughout the series, the duo is consistently 4-fingered - and that includes other close-ups that were also created with real hands briefly replacing the animation.
Continuity mistake: When the kids in the chorus become possessed by the ghosts and run out of the room, Juniper is standing alone by the piano, still wearing the chorus robe. In the next shot, the chorus teacher is now standing next to her, and she is not wearing her robe.
The Marriage of Lupin III - S1-E1
Continuity mistake: When Fujiko stands from the banquet table, the fork and knife disappear from Jigen's plate. (00:05:00)
Continuity mistake: When King mentions the two brothers' "destiny", his big feline is at Young Diabolik's side, facing King and the others. Aerial shot, and the panther is at King's side facing Diabolik. (00:05:00)
Coach Fussell's Lament - S2-E5
Continuity mistake: Chairface and Chrome Dome arrive at the Brianchild's house in the same car, but drive off in separate cars.
