The first time that the main villain is defeated without the use of the Zords.
The flashback footage of the Singing Squash shows Mysterious Wizard Barza, the Rangers' mentor, in the original Japanese series Kyoryu Sentai Zyuranger.
The Terror Toad refers to Trini as "bud", likely because the Yellow Ranger in the original Japanese show is male. This is also why Kimberly's Pink Ranger wears a skirt but the Yellow Ranger does not.
This episode marked the second time, after "Big Sisters" that the main plot of a Super Sentai episode was also used in Power Rangers outside of mere footage requirements (in this case, the plot being the Blue and Pink Rangers being turned into punks with the only cure being a rare herb).
This episode would be mentioned again by Kimberly in "Island of Illusion".
