Inter-Dimension Detention - S3-E16
Continuity mistake: When Crowler and Bonaparte scream after seeing Sapphire Pegasus, they are shown facing the monster directly. There is quick cut to Sapphire Pegasus holding Winged Kuriboh in its mouth, but when the shot cuts after that, Crowler has rotated 90° and Bonaparte has turned around entirely to face the other characters. (00:05:04)
Inter-Dimension Detention - S3-E16
Continuity mistake: When Jesse says to Jaden and Hassleberry that they should go inside, his body is facing toward Jaden, but when the shot cuts, his body is facing toward the academy. (00:05:38)
Inter-Dimension Detention - S3-E16
Revealing mistake: When Chazz says Jaden can have his bed, a weird animation error occurs regarding the bed. There is a white bedsheet that covers the mattress, and a small shadow can be seen underneath the pillow and duvet. When he starts to get up, the bedsheet momentarily switches to the colour of the shadow midway through the shot. (00:06:10)
Inter-Dimension Detention - S3-E16
Other mistake: When Chazz gets out of the hospital bed, he appears to be fully dressed, including wearing a jacket, trousers and shoes. There would be no reason for him to be dressed head to toe in that moment. Even if the nurse didn't remove any of his clothes, it would be unrealistic for him to be wearing his jacket, his belt or his shoes while resting in bed, and would've probably been removed when he was admitted. (00:06:10)
Inter-Dimension Detention - S3-E16
Deliberate mistake: When the Harpy trio attack Sapphire Pegasus, there is shot of them taking a swipe at him one at a time. This shot is repeated a few seconds later, as the body movements from all the characters are exactly the same. (00:12:12)
Inter-Dimension Detention - S3-E16
Continuity mistake: When Blair is explaining to Jaden that the creature scratched her with its hand, in the following shot where the scratch on her arm is shown, her legs are bare. Two shots later, she is suddenly wearing tights. (00:19:42)
Continuity mistake: When discussing how to treat Blair, Bastion says "I'm sure a real hospital would be more than capable of helping her" and Jaden, who is sitting right next to him, turns his head to face Bastion. In the next shot, Jaden's body has rotated 90° and is facing Bastion directly. (00:03:00)
Continuity mistake: When Miss Fontaine hands Jaden the paper with the medicine list, she is holding it in her left hand at first. When the shot cuts, the paper is in her right hand. (00:03:23)
Continuity mistake: When the students are all speaking with Crowler in the Chancellor's office, they are all shown facing the desk directly. They remain in the same position throughout the scene, but when Bonaparte runs into the room, they are suddenly facing away from the desk. (00:03:47 - 00:04:57)
Revealing mistake: Just after Crowler asks himself why all the important decisions fall on his shoulders, the shot cuts to Syrus, Alexis and Hassleberry. Hassleberry says "What'd you talk yourself into doing, Professor" and puts his hands on his hips. When he does so, his left hand passes through his trouser leg. (00:04:14)
Continuity mistake: After Jaden and the gang leave Duel Academy, Marcel places a monster card on a duel disk. The monster card is in his right hand, but in the close-up of the card being placed on the duel disk, the card is in his left hand. (00:06:45)
Continuity mistake: When walking to the submarine, Jaden stops walking and Jesse asks "What now?" At this moment, Jaden is standing with his body rotated 90° perpendicular to Jesse, but when the shot cuts to Jaden, he has suddenly rotated so that he is facing Jesse more directly. (00:06:50)
Continuity mistake: After Jaden suggests they use their duel monsters to fly to the submarine, Jesse raises his right hand and tells him that the bio-bands are still draining their energy when they use monsters. When the shot cuts, his right hand is suddenly lowered. (00:07:00)
Continuity mistake: When Adrian is tempted to let go of the rope, Jim puts his hands on the rope before Adrian can do so. In the shot of Jim putting his hands on the rope, he places his left hand over Adrian's left hand. When the shot cuts, Jim's left hand is on Adrian's wrist. (00:09:02)
Other mistake: When Jesse summons Crystal Beast Cobalt Eagle, the Life Point count is displayed instead of the Attack Point count. (00:11:18)
Continuity mistake: When the scorpions begin entering the room, in the shot from behind Jaden and the gang, Jim is shown standing right beside Jaden. But in the next shot, Jim is behind Jaden. (00:16:55)
Continuity mistake: When Jesse summons Crystal Beasts Amethyst Cat and Topaz Tiger, in the shot of them approaching the scorpions, they are standing right next to each other, at 45-degree rotated angles. In the next shot, they are no longer positioned at a 45-degree angle. (00:17:25)
The Night of the Living Duelists - S3-E18
Continuity mistake: When Bastion is writing a really long equation on the walls, the piece of chalk he is holding is level with his neck, but in a closer shot, the chalk is raised above his head. (00:02:58)
The Night of the Living Duelists - S3-E18
Continuity mistake: When the Duel Ghouls are trying to get into the nurse's office, Ms Fontaine tries to make an emergency call on her device. Her fingers are placed over the back of the device, but when the shot cuts, her fingers are placed over the side of the device. (00:14:50)
The Night of the Living Duelists - S3-E18
Revealing mistake: When the Duel Ghouls are approaching the main characters, in the shot where Chazz walks to the front of the crowd, there are three ghouls who are drawn black, with no facial features or clothing, to give off the impression that they are shadowed. (00:16:00)
