Season 1

After the others criticize Dale's sloppiness, he accidentally falls into a city garbage truck while cleaning up. In the rescuing of Dale, all the Rangers end up on a garbage barge heading out to sea. Chip and Dale get captured by P1-rats who live under the sea in an upside down 17th Century galleon. Monty poses as "Long Lost LaFitte" (the captain of the ship's rats) in order to rescue Chip and Dale. A menacing octopus (Billy the Squid), provided additional jeopardy as they release the ship's treasures causing the galleon to finally rise to the surface.

In helping a little girl find her lost kitten, the Rescue Rangers find it has been kidnapped along with thousands of other cats. Professor Nimnul, a mad scientist-type, is capturing the cats, by using giant robot bulldogs, for use in making a giant static electricity generator. In hopes of terrifying the world, he holds the city ransom with lightning bolts. The Rescue Rangers save the day, rescuing all the cats and bringing Mandy's kitten home safely.

At the end of their vacation, three shape-changing aliens, Bric, Brac and Dtz, have to leave Earth but Dtz sneaks off and stays behind. When science fiction fan Dale meets Dtz, he convinces the alien to take his shape. Soon Dale has Dtz doing all his chores, and the rest of Rangers are shocked at sloppy Dale's new behavior. Bric and Brac demand that Dtz return home, but Dtz sends Dale in his place. Bric and Brac, worried that Dtz (actually Dale) is becoming too Earthlike, decide to freeze him and take him home to Reeblebrox for treatment. Dale escapes only to find he has to prove he's the real Dale.

Dale's TV hero, FLASH, the Wonder Dog, is kidnapped by Fat Cat and his henchmen in a plan to destroy the famous dog's reputation. Fat Cat and his minions dress up in Flash costumes and vandalize the city. Dale convinces the other Rangers to find Rash, and in doing so he discovers that Flash is not the hero that he portrays on TV. Fat Cat makes a final attempt to discredit Flash when he goes to the TV studio in a Flash disguise and attacks Conrad the Cockatoo, Rash's sidekick. With the Rangers' help, the real Rash overcomes his fears and saves the bird and clears his name.

The Rescue Rangers visit the Space Center to watch a launch. After trying out the test equipment in the Astronaut Training Center, Chip and Dale are trapped in a spacesuit and taken aboard the spaceplane, which is launched into space. When the astronauts release a satellite into space, the spacesuit is accidentally released also. Gadget designs a rocket fueled with TNT and -- along with Monterey, and Zipper -- flies out into space to save Chip and Dale and hitch a ride home on the Spaceplane. But a meteor hits the Spaceplane and knocks the astronauts unconscious. Chip and Dale, using their astronaut training, manage to land the Spaceplane safely... although the astronauts get the credit.

Deep in the jungle, a tribe of wingless kiwi birds have stolen the Ranger Plane to worship as a god. When the Rescue Rangers steal the plane back, Dale injures his toe. He plays up his small injury for Gadget's attention, which upsets Chip who knows Dale's just faking. When the Ranger plane crashes in the middle of the jungle, the Rangers must carry it back to civilization. Gadget converts it into a boat and they float down the river, narrowly avoiding the open jaws of a crocodile. When Chip takes the other Rangers into the jungle to prove that Dale is faking his injury, they are kidnapped by the Kiwis. Trying to save his friends, Dale gets his bandages tangled in the trees and appears to flying.
