Having finally reached "Doomsday" in my own watch, I can make a couple more comments. First, it is obvious the Goldar footage is probably more or less refilmed since so much of it is clean compared to the grainier Zyuranger footage. Most of it is just Goldar doing his "WWE boasting" and boosting his character (since he was much lazier in Zyu), but it includes things such as introducing the Green Candle compared to how it was in Zyu. (since here it was Rita's and there was no Clotho)

As for the prom idea, I think the closest I can see that it exists potentially is the whole sub-plot of "The Green Candle". They seem to make a big deal about this dance coming up and that the arc ends with Tommy and Kim finally getting together as a couple without the dance happening. It seems to success the prom could have happened in the story, but they instead end up changing it later to "Power Rangers Day" for the "Doomsday" storyline. It worked (since I do admit that having a day celebrating the Power Rangers works as a good season finale or to end the story), but it does make me wonder where the prom/dance arc went...and if they had to change it because too much of it relied on the footage of "Bubba" (the name they were going to use for Kai if they used him for Cyclopsis as opposed to Goldar). I also wonder if any of the other episodes pre-Doomsday would have likewise built up to the prom...which I doubt but mostly since that would have included a few ending-story episodes that would probably make no sense with this plot. (as bad as "Clean-Up Club" was in some way, that was an end-game Zyu story and probably one of the few they could make work compared to others)
