Celebrity Voice Actor: Kathleen Freeman as Ma in "Short Order Crooks"; Deborah Walley as Buffy Ratskiwatski ("Out of Scale"), Lahwhinie ("Gadget Goes Hawaiian"), and Foxglove ("Good Times, Bat Times"), Carol Channing as Canina LaFur ("A Chorus Crime" and "They Shoot Dogs, Don't They").
Cross-Dressing Voices: Chip and Gadget were both voiced by Tress MacNeille (though, for Chip, you wouldn't know it from hearing at first since Tress's voice was placed at a higher pitch to match the original voice actor for Chip from the old Donald Duck cartoons).
The Danza: Dev Ross as the TV aerobics trainer Dev in "Battle of the Bulge".
For no apparent reason, the shot of Chip acquiring his hat in Part 2 of the pilot is missing from reruns and even the DVD.
"The Pied Piper Power Play" was largely re-cut to remove a deaf-mute character named Mouseo that Disney execs felt was a negative stereotype. At least half the story is changed by his removal.
Several episodes were edited for Toon Disney, including edits that take out fade-outs to commercials and replace them with horribly-put-together cuts between scenes. What makes this worse? The Toon Disney cuts are the ones used for the DVDs.
The episode "A Lean on the Property" was never shown after the September 11th attacks because the story involved Fat Cat levelling skyscrapers by using moles.
The episode "Dirty Rotten Diapers" redubbed Gadget's lines about hurting the midget criminal posing as a baby (i.e. "Trash the brat!" was changed to "Trash the bum!" and "Let's shake that baby 'til he rattles!" was changed to "Let's shake that bum 'til he rattles!") because the censors thought it would bring about complaints of child abuse. The Toon Disney run had the original lines.
In the original version of "Puffed Rangers", the villains were crooked Japanese auto executives who spoke in stereotypically Asian English and there were a lot of jokes about China and Chinese culture. In the reruns, the auto executives spoke clear, grammatically correct English and all of the China/Chinese jokes were altered or excised.
The title chipmunks were originally not going to be a part of the show, as it was going to be a The Rescuers' spin-off with original characters; execs insisted on established Disney characters to headline the show instead, and as soon as the creators saw Chip and Dale's names on a list, they agreed to use them.
Fake Nationality: Lots of characters from all around the world meet a pretty much 100% American voice cast.
Hey, It's That Voice!: Lots of occurrences in the American dub. Would you believe that Tress MacNeille is Chip and Gadget? The Gadget voice can be picked up easily, since Tress has used that voice in other cartoons. The Chip voice, however, was achieved by having the voice pitched and sped up by the studio sound system.
Zipper is Nami in the second dubbed version (in the first one, Zipper keeps his English voice instead).
Fans of Elvis Presley and "Beach Party" movies may recognize the late character actor Deborah Walley as Foxglove and Lawhinie; she later in life visited the fandom's message board on occasion and regularly communicated with CDRR fans.
Carol Channing guest starred as Canina LaFur in the episodes "A Chorus Crime" and "They Shoot Dogs, Don't They?".
Keep Circulating the Tapes: The show has never been aired on American free TV since 1993. It did air on cable (on both The Disney Channel and Toon Disney) in the late 1990s/early 2000s, but now that's gone too due to Network Decay. The entire Season 3 has still not been released on DVD yet, it's being removed from YouTube again and again, and the few copies of the "Witcheroo" VHS tape are far from being sufficient for the many Foxyphiles, not to mention that probably only few of them still have a VHS recorder. And as noted above, even the existing DVDs suffer from censorship.
On the other hand, many non-US networks keep airing reruns of the show from time to time.
Missing Episode: "A Lean on the Property" was banned in the USA post-9/11. It's not on the two released DVD sets, either.
No Export for You: The Season 2 DVDs and most of the merch available in the USA can hardly be acquired anywhere in Europe (or anywhere else in the world) other than on eBay.
Monterey Jack was voiced by Peter Cullen in Season 1, but was replaced by Jim Cummings for the second season (and the five-part pilot episode "To The Rescue"). According to series creator Tad Stones, Cullen wasn't as funny as Cummings was during table reads.
In the first episode of the German dub, "Kiwi's Big Adventure", Gadget has a different voice that hardly even fits her.
Screwed by the Network: 51 of the show's 65 episodes have been released on DVD in two sets. Disney has made no announcement about when the remaining 14 episodes (including Missing Episode "A Lean on the Property") will be released...if ever. As if that wasn't bad enough, the Five-Episode Pilot "To The Rescue" was only released in its five-part syndicated version (not the "movie" form), and the episodes' Toon Disney cuts were the versions put on DVD.
Happens all the time as Chip and Gadget both got their voice from Tress MacNeille. It doesn't sound awkward only because Chip's voice is pitched up—thus making Tress MacNeille the very rare voice actress who actually hits on herself.
Also happens with Dale and Zipper, since they're both voiced by Corey Burton, although Zipper rarely has "speech" per se.
The same goes for Mole and Snout, though to a lesser extent.
What Could Have Been: The early draft known as Metro Mice featured a different-looking Gadget, an Australian kangaroo rat and proto-Monty named Colt Chedderson, a far-sighted eagle named Eagle Eye, a Martial Arts-savvy, baseball-crazy cricket named Chirp Sing, an adventurous mouse named Kit Colby as the leader, and a chameleon named Camilla. Concept art was created with Kit, Colt, and Gadget. In the end, all that was taken over into the final version were Gadget with some modifications, Colt with a new name and a new species, much of Kit's attitude plus his aviator jacket for Chip, and the name Chirp Sing for an entirely different character.
It was also originally going to have Bernard and Bianca from The Rescuers too.
