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.
The Catwoman from Channel Six - S2-E12
Plot hole: April is transformed into a Catwoman by a teleportation accident. Shredder puts a mind control collar on her, and she attacks the turtles. The turtles manage to remove the collar, and the fight ends. Shortly afterwards, April returns to her normal form, without any explanation.
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".
