Due to matters of "Mommy Fearest", This episode of the Powerpuff Girls was banned due to Child Abusing.
This episode was the second produced episode of the series, but it aired first because Cartoon Network often airs episodes out of production order, becoming the series premiere. Insect Inside/Powerpuff Bluff (1998) was meant to be the series premiere but was held off to the second episode.
Whether the lady with the pie was actually Sedusa in disguise or just a normal person remains ambiguous, as it was never mentioned in the episode. However, in the credits for the episode, "Neighbor Woman" and "Ima Goodelady/Sedusa" are listed as two different characters and they even have different voice actors, implying that they are in fact separate people and that The Powerpuff Girls did indeed beat up an innocent civilian. It's also possible she might be a separate villain using similar tactics to Sedusa.
This is the very first episode of the series.
