Character mistake: Throughout the entire series, the Turtles are referred to, by others and by themselves, as amphibians. But turtles are reptiles, not amphibians. However they are amphibious, amphibious reptiles.
Audio problem: When Donatello tries to stop April from leaving the sewers after she accuses them of committing the robberies, he is speaking in Raphael's voice. (00:10:35)
Deliberate mistake: When the turtles and April escape the building filling up with water, the shot where the hall is filling up with water is used twice.
Revealing mistake: When Donnie is fighting some foot clan solders, his belt has an M on it for a frame.
Revealing mistake: When the channel 6 crew member is telling April they should go, his hand disappears for a frame.

Continuity mistake: When Leonardo slices Bebop's gun, he's wearing red.
Hot-Rodding Teenagers from Dimension X - S1-E4
Other mistake: General Traag's weather weapon causes a blizzard across the city, yet when the Turtles and the Neutrinos come up to the surface after the blizzard had been occurring for a while, none of the cars parked on the street, including the Neutrinos' two flying convertibles, are covered in snow. The interior of their cars should have been full of snow.
Invasion of the Punk Frogs - S2-E8
Plot hole: Shredder meets the frogs for the first time and gives them clothes using the holographic projector. The frogs continue to wear the same clothes for the rest of the episode, even without Shredder being around.
Continuity mistake: The turtle van falls on a bridge, the turtles escape swimming. Shortly afterwards, April appears driving the van, looking for the turtles.
The Catwoman from Channel Six - S2-E12
Continuity mistake: While April is in Shredder's lair taking photos, when the cat shows up, it has a tail with a white tip and a white underbelly. However, when Irma shows April's photographs to the Turtles, the cat in the photos has a solid tail, though the cat's white underbelly is shown properly.
The Catwoman from Channel Six - S2-E12
Continuity mistake: When Irma meets the disguised Turtles at the subway station, Irma speed-talks her explanation of April's situation. Mikey then tells Irma, "Rewind that and play it back at normal speed," as he raises his right arm, with his left hand in his trench coat pocket; the newsstand is missing in this closeup as well. It cuts to a wide shot, and now it's Mikey's left arm raised in the air (also note his orange wristband is missing).
The Catwoman from Channel Six - S2-E12
Continuity mistake: The watch on Irma's left wrist repeatedly appears or disappears between shots, as well as mid-shot, and it even switches to her right wrist. Two examples: at the subway station, Irma walks toward the Turtles, and her watch switches from her right wrist to her left; when Irma finally meets her "dream man," the "hunky Splinter guy" in the sewer lair, her watch vanishes.
The Catwoman from Channel Six - S2-E12
Other mistake: When April locates Shredder's lair, as she approaches the matter transporter, April's white boots clip through the transporter platform before she steps up onto it.
The Catwoman from Channel Six - S2-E12
Continuity mistake: After April ends the interview with the contest winner, when Vernon says, "Ok, that's a wrap," he's wearing headphones without an antenna, but in the next shot an antenna suddenly appears at Vernon's left earpiece, then promptly disappears.
The Catwoman from Channel Six - S2-E12
Other mistake: When the Turtles finally reach April's apartment window via the fire escape, as they approach Irma at the couch, Raph's legs clip right through the coffee table and the vase with flowers.
The Catwoman from Channel Six - S2-E12
Other mistake: After Shredder transports Bebop and Rocksteady back to his lair, he joins them on the transporter platform. Shredder then demands to know the exact location of the TMNT hiding place. When Rocksteady mutters, "And then, umm, we went that way," both Shredder and Bebop partly step off the transporter platform, so they're partially standing in mid-air.
The Catwoman from Channel Six - S2-E12
Continuity mistake: After April complains to Vernon about doing stupid human interest stories, April walks toward the back of the news van. In the overhead shot, the van has one large back window, but it changes to two small windows in the following shots.
The Catwoman from Channel Six - S2-E12
Continuity mistake: The tri-circle symbol on Splinter's robe is either on his left side or his right side, or even vanishes entirely between shots, such as when April is the mutant Catwoman and approaches him in the sewer lair.
The Catwoman from Channel Six - S2-E12
Continuity mistake: Throughout the episode, while April is either her normal self or a mutant Catwoman, April's wristwatch suddenly appears, disappears, and reappears, even mid-shot; such as when she's in her Channel 6 office and throws the vase at Vernon.
Chosen answer: The Turtles' pizza obsession was not in the original comics, which were far more adult in the violence and language they contained. Peter Laird, one of the comic's creators was critical of this aspect on his blog in 2012, saying if he had control over the 80s cartoon's creative direction, the Turtles "would not have been so ridiculously obsessed with pizza".
