All of the Spit Flower footage which includes its Giant footage is ZyuRanger footage.
This episode features the first time all 5 Rangers are in the cockpit of the Dragonzord in Fighting Mode.
This is also the first American appearance of the Green Ranger costume with his holster. As you can see, the people in charge of the holsters for Power Rangers weren't paying attention due to the fact that in American scenes, his holster is white whereas in ZyuRanger footage, it's black.
