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.

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.

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.

Other mistake: When Irma finds April's Turtlecom and fortuitously contacts the Turtles, Leo answers the call and holds up the communicator in his right hand. The problem is that in the close-ups of Leo's open communicator, the animation of his wrist area is not complete, so his hand looks disembodied. Additionally, after Leonardo answers the Turtlecom call from Irma, she asks, "Who are you?" and in the next shot of the Turtlecom Irma is holding up, we see Raphael moving his lips as he says, "I'm Leonardo."
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.
