Day of the Dumpster is the first episode of Mighty Morphin Save-Um Rangers and the series premiere of the Save-Ums franchise. It will be broadcast on Discovery Kids.

Synopsis
Following the accidental release of long-imprisoned evil space-sorceress the Shadow Queen, a benevolent sage known as Princess Rosalina drafts a group of five kids to help protect the planet as dino powered warriors of goodness.

Plot
Somewhere in the Solar System, two astronauts are surveying the landscape when they find what looks like a dumpster. When they open the dumpster, the astronauts are knocked to their feet as Evil Space Aliens come out of it. Shadow Sirens and their leader, the evil sorceress Shadow Queen, exclaim their gratitude to the astronauts for freeing them after 10,000 years of imprisonment and announce their plans to celebrate by conquering the nearest planet -- Earth!

In the city of Angel Grove, California, five kid friends named Jazzi, Custard, Noodle and Ka-Chung are at the Save-Um Central. Ka-Chung and Foo are sparring in front of a karate class, and the less-than-athletic Noodle is among the students. Jazzi is taking care of her brother B.B. Jammies and Custard is training yoga, but they are interrupted by a pair of rude bullies named Bowser Jr. and Ranamon, who try to hit the girls up for a date. When they start getting physical, the Save-Ums flip the bullies to the floor and leave them out cold.

High above Angel Grove on Earth's moon, Shadow Queen and her monstrous allies have taken over an ancient Moon Palace as their lair, where Shadow Queen sets up her telescope and eagerly anticipates her conquest of the blue, defenseless planet as she observes its beauty. To facilitate her conquest, her loyal servant Finster has established a laboratory where he is at work molding clay into humanoid dolls called Shadow Pets. By running them through his Monster-Matic machine, the dolls come to life as human-sized soldiers.

Back in Angel Grove, Bowser Jr. is cutting into Jazzi's babysitter and demanding that he be taught how to beat people up. Jazzi explains that babysitting is not about violence, but she nonetheless demonstrates to Bowser Jr. and lands him on the mat again. The class over, Jazzi meets up with her friends at the adjoining Juice Bar. Suddenly, a large earthquake rocks the Youth Center and everybody panics. Before any of the five friends can react, they are teleported out of the Youth Center in beams of light.

As their vision recovers, the Save-Ums find themselves in a high-tech facility unlike anything they've seen. A strange humanoid princess comes out, which amazes Custard at how technologically advanced he is, but their attention is then turned to a booming voice coming from a glowing head in a nearby tube. She introduces herself as Princess Rosalina and her robot aide as Luma, then explains to her guests of Shadow Queen and her plans to conquer Earth. Though Rosalina had defeated Rita long ago, she is no longer able to fight due to her sorcery and thus has chosen five "overbearing and overemotional humans" (kids, in other words) to become Earth's defenders in his stead. The Save-Ums are incredibly skeptical at this information, but Rosalina grants them Power Morphers that will allow them to summon the incredible power of the colors and fight Shadow Queen's forces.

Leaving the Command Center, the Save-Ums are still unable to fully believe what they had just seen, but their attitudes change when Shadow Queen's pets arrive to destroy them. Though they are able to hold their own with their fighting talents, the clay creatures prove too much and they are forced to gamble their lives on their Power Morphers. As this power is summoned, the Save-Ums are given colored costumes and helmets, and their strength increases, allowing them to defeat the pets.

They are then teleported back to Angel Grove, where Shadow Queen's warrior Goldar awaits them with more pets. As the pets fall, Shadow Queen throws her magic wand down to Earth and uses its power to make Goldar grow to colossal size. Driven by inherent instincts granted through their powers, the young heroes summon giant robots in the shape of the dinosaurs, the Dinozords, and use them to fight Goldar. They eventually join their Dinozords together into a single robot, the Megazord, which overpowers Goldar and forces him to retreat. On the moon, Shadow Queen comes down with a sudden headache over her loss and blames Goldar for it.

Back in the Command Center, the Save-Ums have now fully accepted Rosalina request to protect Earth from Rita's evil plans. As per Rosalina's rules, they are required to never use their powers for personal gain, to never escalate a battle with them unless forced, and to keep their identities a secret from all. With Rosalina and Luma guiding them, a new team of superheroes is born -- the Mighty Morphin Save-Um Rangers!
