This marks the introduction of the phrase "It's morphin' time", and is coined by Zordon (David J. Fielding).
The scene where the Rangers fight the Putties while unmorphed was filmed on location at the Vasquez Rocks.
Billy Cranston (David Yost) creates the Rangers' communicators and introduces them to the teens in this episode. The communicators allow the Rangers to talk to each other and the Command Center and allows them to teleport.
Trini translates Billy's "scientific" talk for the first of many times.
