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.
Bug Off/The Crawl Space - S9-E5
Continuity mistake: In Moving Away, Tommy tells the other Rugrats how they first met when Angelica lied about the nasty things they did. However in the Crawl Space, there is a flashback of Tommy, Chuckie, Phil and Lil playing in the playpen when they were younger. Chuckie is scared of the Jack-in-a-box in that flashback, so the Rugrats could not have met for the first time back then.
Continuity mistake: During the second review of the class's commercials, a pink paper airplane changes hands between Tony and Angela without being tossed or passed.
Factual error: In "The State Vs. Chip Douglas", Ernie finds his missing 1914-D penny when it falls out of his pocket. A close-up shows an Indian head penny lying on the floor. The problem is that Indian head pennies were not minted after 1909.
Coffee Quest/Phoenix Rises - S1-E18
Other mistake: In Phoenix Rises, when Phoenix runs away, the Big Coffee sign is missing.
Factual error: The conversation between Taylor and Michelle tells us that school is over for the day and that Taylor talked to her crush at lunch. When the boy shows up at the bakery later, he and Taylor plan to meet at 3 that afternoon; if its before 3, they should still be in school.
Factual error: When Ralph goes out the window onto the fire escape to save Ed the first time in the episode, Alice is looking out the window (to her right) telling Trixie all the step by step movements of both men, ending with, "and he's taking him right into your window." The Norton's live directly upstairs from the Kramdens, but Alice never changes the direction she's looking at the whole time. She should be looking straight up as Ralph leads Ed into their window. There is no other window to the right. (00:02:30 - 00:03:04)
Winning Through Intimidation - S1-E15
Continuity mistake: Panik's Metal Guardian can be seen on the field several minutes before he actually plays it. (00:10:30 - 00:13:00)
Continuity mistake: In the episode where Fester invents a fabric: When Fester lies down on the parking lot, his head is first pointing upwards, towards a car, then in the next shot he has turned 90 degrees and his head is pointing towards Norman's legs.
Factual error: When PC Plum picks up a set of keys from the table, Eadie McCredie claims they are her keys for her minibus. She drives an LDV Convoy minibus and the key is from a Vauxhall, a completely different design.
Continuity mistake: When the girls are in Cleo's room after discovering her magical singing, she says, "People love me. Adore me. Aren't I adorable?" She then turns to look in the mirror. Her hands are on her waist in the close-up, but by her side in the wide shot. (00:12:59)
Kessei! CLAMP gakuen tanteidan - S1-E1
Continuity mistake: Nokoru Imonoyama is looking at the dossier about the brother-in-law of their client. The chart showing the sorry state of his business looks different from the close-up when Nokoru puts it down - for instance, it's bi-color grey and white, when it was simply with white background before. (00:13:15)
Speeding Is Dangerous - S1-E22
Other mistake: When Shine says, "I think I'm OK," his front tire is layered over the railway tracks.
Other mistake: In this episode, Eric tries to destroy a mutant, apparently unaware that Rangers don't destroy mutants but freeze them. Yet in Quantum Quest and Clash for Control, he froze a mutant.

Revealing mistake: Whenever Isis has to do jumps you can tell it's not her but a stunt double.
Episode #1.5 - S1-E5

Who Burned Mr. Brinker's Store?: Part 1 - S1-E6
Other mistake: The arson investigators name Jamal as the main suspect in setting fire to the store, because the security camera caught him sliding something through the front door mail-slot. Any arson expert would immediately know that it wasn't Jamal that started the fire, as the fire's point of origin was in the back of store, and was also entirely contained there, and Jamal was not only nowhere near the back of the store, but was also outside.
