Revealing mistake: The "hostage" episode reuses footage from the "Dinosaur" episode, which doesn't totally fit. When the giant crabs attack and destroy the group of houses on the island, the longshot of the damage is recycled from the earthquake episode - including an earth fissure, something the giant crabs wouldn't and probably couldn't have done.
Misty's Magical Mix-Up!/Bone's Lucky Doubloon - S2-E31
Other mistake: In the episode "Bone's Lucky Doubloon," Captain Hook, Smee and another pirate are washed downstream, go over a waterfall and land in a lake. When they emerge from the lake, no water is dripping from them.
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)
Continuity mistake: When Benny comes to Top Cat's dustbin at the start of the episode, he first pushes a door bell and then uses a handle to knock on the dustbin. In the next shot, both the bell and handle have disappeared.
Character mistake: Professor Saotome checks the status of the Getter Robot when his son falls unconscious. The HUD output is written in awkward EngRish, from the first line of the status report, called; "Monitor the state of affairs", to smaller details like the article randomly used for certain lines ("a control device, a correspondent"). The biggest flub though is that the name of his son is "Tatsuhito", in proper romanization, but here appears as "Tatuto." (00:05:20)
Continuity mistake: In the opening credits, Popeye is helping Olive Oyl put her washing on the line. When Bluto appears, he takes Popeye and uses one peg to hang him on the line, but in the next shot he is hanging by two pegs.
Factual error: When the militia come in to shoot Woody, they're holding pump action shotguns and you hear them pump them (meaning chamber a round so it's ready to shoot). Even if we assume Malloy and Jorge did not do this, we see/hear them both pump the shotgun twice (without ever shooting in between). However, pumping the shotgun after a round has been chambered will eject the round, in the case of Malloy and Jorge an intact round, not just the shell, would be ejected. However, we never see anything be ejected.
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)
Just the Right Distance From the Sun / Solar Power Rover - S1-E3
Continuity mistake: In "Solar Power Rover", when they open the gate to DSA, the lock switches sides.
Continuity mistake: The episode "Clash Reunion" shows Megavolt in his flashback becoming a supervillain in high school. For one moment he's wearing his trademark goggles, then afterwards they're gone. (00:05:05)
Continuity mistake: The quantity of super-steroid in Fukegao (the mad scientist) 's test tube changes continuously between shots. (00:11:00)
Pink Arcade / Life With Feather (pilot) / Pink S.W.A.T. - S1-E2
Continuity mistake: Pink Arcade: When the Pink Panther picks up the money that comes out of the scales, the amount of coins changes between shots.
Beauty and the Obese: Part 1 - S1-E1
Continuity mistake: Right after the opening scene where the model suddenly inflates to fat, we are taken to The Tender Loins club where the exterior shot shows a line of people with a bouncer checking each one. In this shot, his arms are down at his side, but then it cuts a close up and suddenly he has his hand lifted to his face looking at someone's I.D. (00:01:40)
Other mistake: Two Tiffs can be seen for a few seconds when King Dedede and Escargoon drive in.
The Left Hand of the Magician - S1-E5
Continuity mistake: Fujiko opens the suitcase on her motorbike with the left arm, right arm, left arm, depending on the camera angle. (00:19:45)
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)
Polly Wants a Treasure - S1-E8
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
Visible crew/equipment: When Florence tosses the note off the fridge when she and Putty enter the apartment, the rod holding the paper is very visible on the far left of the screen.
Ranma o gekiai! Shintaisou no sukeban toujou - S1-E11
Audio problem: Kodachi grabs weapons from her locker and jumps in the night to go deal with Akane. She laughs maniacally but her mouth is shut. (00:07:55)
