Yoko - Season 1 Episode 48 Hello Nature

After observing how hard Ranger Loops works, the kids decide that they'll be Rangers for one day. They focus on keeping people from doing things that may harm the park, but somehow they get a little power-mad, and people in the park, not too fond of their bossiness, start leaving in droves. When the kids see the park so lonely and sad, they realize they need to rethink their methods. With Yoko's magic, they go back in time and start from scratch.
