Worlds Collide: Part 3 - S3-E6
Plot hole: In their previous encounters with the Triceratons, the Turtles had to learn the hard way that the Triceratons breathe not oxygen but a combination of nitrogen and sulfur, which is detrimental to most Earth lifeforms, and thus had to wear special rebreathers. When the Turtles, Splinter, April and Casey enter Zanramon's throne room along with Traximus, none of them wear any breathing equipment to protect themselves from the hostile atmosphere.
Revenge of the Monsters - S1-E38
Continuity mistake: The episode is about Ty being put on trial for his attacks as the Wirewolf in the episode of the same name. The problem is that "Revenge of the Monsters" is a Season One episode and the episode "Wirewolf" didn't appear until Season Two.
Suggested correction: "Wirewolf" originally aired on October 28, 2000 while "Revenge of the Monsters" originally aired on November 14, 2000. In the context of the show, there's no continuity mistake. When they reordered the show and put them into Season 1 and Season 2, the first 7 episodes of season 2 are out of order (according to original air date). For example, s02e01 aired after s01e14.
Even though "Revenge of the Monsters" aired on November 14, 2000, and as a season one episode, the episode "Wirewolf" is a Season two episode so it still constitutes as a continuity error.
No. You missed the point completely. "Wirewolf" was produced BEFORE (production code 011) "Revenge of the Monsters" (production code 045). Therefore, there is no continuity error for the show. The order of the episodes were then later changed, which isn't the fault of the show. If you watch the episodes in order they were produced instead of the order they're listed in IMDB, there isn't a mistake.
Deliberate mistake: Season 2, episode 6 "Identity Crisis": When Bizarro starts decaying into the parody form of Superman, his costume goes with it; the blue fades, and even the 'S' insignia changes. Strange that superhero garments change right alongside their wearers when they suffer from an unstable genetic effect. Were the clothes cloned right onto his body, instead of sewn?
Spider's Little Daddy/Tricycle of Terror - S3-E1
Continuity mistake: Mandy's working on her report. The page she's on says "CORN by Mandy." A moment later, she writes the same title on another page.
Continuity mistake: When Tsubasa is staring at the soccer grounds sign, it is written with a different layout in different shots. (00:10:10)
Fruit Picking Day/Daniel Is Big Enough to Help Dad - S1-E11
Revealing mistake: When Daniel picks up the can of blue paint, it passes right through the cans of yellow and red without bumping them.
Continuity mistake: When Captain Bragg orders her troops to move in on the people in the square, GS-8 is standing behind her, despite the droid having fled the scene just two shots earlier after Senator Singh's arrest. (00:02:58)
Weirdmageddon: Part 1 - S2-E18
Continuity mistake: Two guys are throwing a frisbee and it lands on the ground. In the next shot, the frisbee is gone.
Triumvirate of Terror! - S3-E8
Continuity mistake: As the pie is flying towards Batman and the reporter, it is going with the food side first and pan side behind it. But when it shows it going to hit, it is suddenly flying pan side first. (00:05:30 - 00:06:35)
Wind Chimes - S1-E9
Visible crew/equipment: In the scene where Mcduff and Johnson are trying to find water since it's extremely hot, they go Under The Bed and notice Alfred under there. Look in the background, for just a split second, you can a man walk past the from the door. It's for only a split second so it's quite easy to miss. (00:06:05)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: As Rhodey tells the guard "You know. As in Stark International, the company you work for!" As he begins saying this, he raises his arm up, which casts a shadow on his chest. While he speaks, it cuts to a side angle and suddenly the shadow from his raised arm is gone. (00:07:05)
'Unmei no sentaku' mitaina - S1-E6
Plot hole: Akito's attack is point blank, on a ship part of a fleet with Distortion Field activated (basically, they have shields, like the good guys' robots). The explosion he causes is according to Ruri's damage report big enough that it managed to vaporize 80% of the ships they were facing, but his Aestivalis and the other 3 right floating nearby make out of it literally without a scratch. (00:05:10)
Continuity mistake: When The Mad Scientist's weapon strikes the Daily Planet, you can see the lights inside the building shut off as it cuts the power to the structure. Yet it cuts to inside the building as workers begin panicking as the building shakes and you can see hanging lights swinging everywhere, still on. (00:07:05)
The Sleeper Shall Awake/Where Walks the Sleeper/The Final Sleep - S1-E11
Continuity mistake: Part 3: As you see the third "Sleeper" (a giant bomb shaped like the Red Skull's head) note the position of the monocle. First it's on its right side, then its left side, and back again to its right side. (00:14:20 - 00:15:05)
Continuity mistake: The package Steve received from Mailbox is briefly visible before Mailbox comes in. You can also see a crew member's hand holding the package as Steve grabs it.
Continuity mistake: When Dum-Dum cuts the rope releasing Chug-a-Boom from the balloon, we cut to the car and you can see Clyde and Dum-Dum are surrounded by the rest of the Ant Hill Mob, but when we see the two in the next shot, the other members are nowhere to be seen.
Continuity mistake: When Daria is on the couch with her dad she's holding a mug but the next shot it's a glass. (00:15:39)
Continuity mistake: When Lemmy falls down from the window and running away from Bowser with Iggy, Iggy's face turns orange. Then later, it turns back to green.
Continuity mistake: When Chris is trying to activate Hummingbird Power, his skin is suddenly lighter than in the previous shot.
Continuity mistake: Before Charlie says to Lola "You must double-triple promise you'll never play with it", he places the rocket beside a black box. Later in the episode, when Lola attempts to get the rocket down to play with it, the rocket is now on top of the black box.
