The Rescuers Review

Although Disney animation was in a slump during the 1970s, the studio still managed to produce the worthwhile Rescuers. A more modest effort than recent Disney extravaganzas, this movie still makes for great family viewing. Medusa is a villainess in the grand tradition of Cruella Deville, and the unlikely voice pairing of Eva Gabor as va-va-voom Miss Bianca and Bob Newhart as the timid janitor Bernard works exceptionally well. They enliven the melancholy Devil's Bayou, a haunting setting if ever there was one.
Because the film is unusually dark (literally and story-wise) a cast of animated misfits adds needed comic relief. Unfortunately this appealing mix is a bit dampened by sappy ballads that accompany some boring slide animation, dating it a little. Otherwise, this is a worthy Disney sleeper

Medusa steals the diamond for herself, attempting to run off with the diamond, leaving Snoops without any shares, and hides it in Penny's teddy bear. When she trips over a cable set as a trap by Bernard and Bianca, Medusa loses the bear to Penny, who runs away with it. After a struggle with Snoops who already turned to her, Medusa retaliates with gunfire, causing the mice to flee until they are met by Brutus and Nero. With help from Ellie Mae and the other animals, Bernard and Miss Bianca trick them into entering a cage-like elevator, trapping them.
Two of the gang set off Mr. Snoops's fireworks, making the boat sink. Meanwhile Penny and the mice commandeer Medusa's "Swampmobile", a motor-boat used by Medusa to travel in the swamp and resembling the front clip Ford Model T body mounted to a small boat, with a single tractor seat for the driver. They get it moving using Luke's homemade moonshine as fuel, while Medusa unsuccessfully pursues them, and is left clinging to the boat's smoke stacks with Brutus and Nero trying to eat her below (because she whipped them while she was chasing Penny) while Snoops is seen rafting away while laughing

The Rescuers Wiki

In an abandoned river boat in Devil's Bayou, Penny, a young orphan, drops a message in a bottle containing a plea for help into the river. The bottle is carried out to sea and washes up in New York City, where it is recovered by the Rescue Aid Society, an international mouse organization inside the United Nations. The Hungarian representative, Miss Bianca, volunteers to accept the case and chooses Bernard, a stammering janitor who has triskaidekaphobia, as her co-agent. The two visit Morningside Orphanage, where Penny lived, and meet an old cat named Rufus. He tells them about a woman named Madame Medusa who once tried to lure Penny into her car and may have succeeded in abuducting Penny this time.
The mice travel to Medusa's pawn shop, where they discover that she and her partner, Mr. Snoops, are on a quest to find the world's largest diamond, the Devil's Eye. They also discover that Mr. Snoops is in the Devil's Bayou with Penny, whom they have indeed kidnapped. With the help of an albatross named Orville, and a dragonfly named Evinrude, the mice follow Medusa to the bayou. There, they learn that Penny was captured to enter a hole that leads down into the pirates' cave where the Devil's Eye is located.
