When the Giant monster appears on Earth, Rita Repulsa's Lunar Palace appears on a skyscraper next to him. The Giant is also holding a full-sized space shuttle, for no apparent reason. This is because the footage is sourced from Zyuranger, in which the episode revolved around the Zyurangers rescuing the space shuttle crew who accidentally freed Bandora (Rita's Zyuranger equivalent).

When the time device is rolling on the roads in Angel Grove, California, and scaring people away, all of the cars that pass by on the streets are driving on the wrong side of the road, meaning that it was Japanese footage. Americans always drive on the right side, while Japanese drivers always drive on the left side.
