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.

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).

Continuity mistake: When Leonardo cuts off April's collar, she asks what happened, but instead of it being Leonardo standing there with the sword, it's Donatello with the sword.
Chosen answer: No, that's just the kind of mistake that gets made when you contract a foreign company completely unfamiliar with the product in question to produce your marketing materials as cheaply as possibly.
