This episode confirms that Bulk and Skull did indeed graduate from Angel Grove High, although it was off-screen and in Zeo.
First and only appearance of the Rescue Turbo Megazord, a combination of the Red Lightning and Mountain Blaster Turbozords with the Wind Rescue, Thunder Loader and Star Racer Rescuezords, used by the Rangers to fight Count Nocturne after the other Zords were too damaged in the battle for the individual Megazords to continue.
