A fun-filled day at the park nearly turns to tragedy, when a runaway baby carriage speeds off alone the hilly sidewalks and open lawn with nobody able to stop it!
Kim, Billy, and Tommy give chase. Three teens from Stone Canyon high school, Rocky, Aisha, and Adam (students of the baby Jacob's father, Mr. Anderson), also follow, with the help of their rollerblades and fancy martial arts moves. Both Kim & Aisha halt the runaway carriage just before it can plummet over the side of a steep hill.
The six teens become fast friends. Later, at a Ninja Championship tournament at the Youth Center, the winning trio of white-suited ninjas turn out, to the Rangers Teens' surprise, to be their newfound friends!
Lord Zedd, wanting to turn these skilled champions into his evil warriors, has Goldar & the Putties kidnap them. They also take Mr. Anderson, which leaves baby Jacob in the hands of some unlikely babysitters: Bulk & Skull!
Rocky, Aisha, Adam, and Mr. Anderson, chained in a cave, await transformation to evil, as the Rangers remain baffled as to where they went.
