The New Kid - S1-E2
Other mistake: At the start when the gang change the time on the clock in the classroom, it wouldn't control the main school clock, plus in every other episode the clock has been operated by The Box on the side of the school, as shown in " The spy who came into the playground".
Other mistake: At lunch, when the kid tells the gang that Spinelli's parents will be the first parents on the space shuttle, Gus's right elbow vanishes, then reappears mid-shot. (00:02:42)
Other mistake: At Parents' Night at the school, when Gretchen's parents walk into Miss Grotke's classroom, Gretchen's father clips through the door. (00:05:46)
Other mistake: When Spinelli's real parents arrive at Parents' Night, the shot is flipped: the potted plant and poster are on the opposite sides, the letter on the poster is mirrored, the door opens the opposite way, and Spinelli's parents are running in the wrong direction. (00:08:26)
Other mistake: When Spinelli's real parents arrive at Parents' Night, as Spinelli's mother tells Miss Grotke, "She just stopped wetting the bed this year," her necklace vanishes, then reappears mid-shot. (00:09:23)
I Will Kick No More Forever - S1-E11
Other mistake: When the gang goes to visit Vince in his house, it shows Vince watching a video of a kickball game. But kids most definitely wouldn't be able to bring a video camera into school, and it most probably would be confiscated by Miss Finster.
The Great Jungle Gym Stand Off - S1-E21
Other mistake: When TJ says that he and the rest of the gang met at old rusty, it shows you a flashback and the kindergartners are wild, but they only became wild when Gus arrives later (as said in All Growed Down).
Suggested correction: It's not true. After Gus "changed" the kindergartners he was sent away from school.
This correction misses the point of the mistake. In "Recess: All Growed Down," when Gus moves to the school, the kindergartners are shown as "normal," but then Gus changes them to be wild, and they start to have torn clothes and paint on them. However, in the flashback scene in this episode, it shows the gang meeting on the first day (excluding Gus), and they have torn clothes and paint on them. This doesn't make sense because they only became that way when Gus moved to the school.
Other mistake: When the gang walks out of the school and Spinelli says, "I can't believe Gus didn't even show up for school today," Gretchen's dress is incorrectly coloured green. Two shots later, it is blue again, as it should be.
Other mistake: When Mikey enters the dance class and Spinelli says, "Mikey?", the letters on the door to Mademoiselle's office are mirrored; the background is flipped in this shot.
Other mistake: When Spinelli sees the man walking multiple dogs, as she asks him how much he gets paid to do it, the poodle's chest fur becomes the same colour as the background twice in two frames. The same thing happens with one of the Dalmatian's legs.
That Stinking Feeling - S3-E11
Other mistake: After Gretchen's Galileo says that Spinelli has a crush on Johnny V, T.J. puts his right hand behind Vince's neck, and his hand and cuff disappear mid-shot. (00:05:21)
Other mistake: The Diggers start digging a hole in the Ashleys' clubhouse, then it cuts to a shot of Gus pouring out the dirt. In this shot, there is a circular object on the roof of the cafeteria building (presumably a satellite dish) that has been left uncoloured.
Other mistake: After the kids start fighting over the treasure, T.J. gives a speech to them. Then, when it cuts back to the other kids, Ashley T's socks are mistakenly coloured the same as her skin instead of green, as they should be. This error is shown again in the shot after the kids drop the treasure chest.
Other mistake: When the gang catches the Ashleys and Randall taking the treasure in the Ashleys' clubhouse, in the shot after Spinelli says, "Since when is Randall an Ashley?", the lines on the wall are mistakenly drawn over the plant in the background.
Other mistake: When Miss Finster drinks the cup of dirt and spits it out, her waistband is mistakenly coloured grey. Then, when we see her again a moment later, it is white again as it should be.
Other mistake: When we first see the gang inside the Ashley's clubhouse, in the shot after T.J. says, "Ladies, you have a deal," there is a big white line at the bottom of the screen behind the characters; the background seems to have been shifted up slightly in this shot.
Other mistake: When Miss Finster walks into Principal Prickly's office, her waistband is mistakenly coloured yellow, but when she starts to leave his office, it is white again as it should be.
Other mistake: When T.J. tells the gang that he is sure that the treasure will make them all millionaires, Gretchen's sash around her dress is mistakenly coloured blue, and in the next shot, it is pink again as it should be.
Other mistake: When T.J. discovers the directions to the treasure inside the old history book, Gretchen's left shoulder is going over T.J.'s desk, and there is a big white line going through the bottom of the desk. It seems as if T.J.'s desk has been shifted up slightly in this shot.
Other mistake: When Miss Grotke gets an old copy of the history book for T.J, she opens the cabinet and takes the book out. When she closes the cabinet, the knob moves higher on the cabinet door mid-shot.
