This is the original pilot episode which was filmed before the Day Of The Dumpster episode we all know and love. This episode was made to be shown to tv executives to see if they would want to show Power Rangers on their channel.

STORY
Five teenagers, who hang out in an average bowling alley, and occasionally use their karate skills to fend off a gang of mean bullies, are summoned to save the world by an intergalactic being named Zoltar. He gives them the power to become Power Rangers, and to call upon giant dinosauric robots called Droids to combat the forces of space witch Rita Repulsa. (Episode synopsis from TV.com)

It seems that the version of Foul Play In The Sky which aired is nothing like it's original plotline where Kimberly was supossed to take a bite out of a poisoned apple and fall into a deep sleep Kimberly was supossed to take a bite out of a poisoned apple and fall into a deep sleep. It's unknown why it was changed. In the first releases of this episode on VHS in the UK the synopsis on the back of the box was for the alternate version and not the new version. Some of the footage of the original episode can be seen in the aired episode.

There's a slightly different version of this 3 part Power Rangers adventure. The rangers throughout call the zords the Ancient Zords. This is most noticable in part 3 when they call out the zord names.
