Chip and Dale

Chip and Dale are a pair of cunning and mischievous chipmunks. Although the duo have similar looks and rarely appear separately, they each have distinct personalities and a few distinguishing physical features.

Chip can be identified by his small black "chocolate chip" nose and a single front tooth, whereas Dale has a larger nose which is red and two adjacent front teeth. Chip is also usually the more logical, positive, and cunning of the two, with Dale being the less intelligent.

Walt Disney anthology series
In a 1959 episode of the anthology series entitled "The Adventures of Chip 'n' Dale", Walt Disney was unable to host the show personally. Instead, he left a message on his tape recorder informing viewers of his arrangements to have Chip and Dale host in his place. The chipmunks use the time to go through an old book which holds memories of their fondest exploits.

Chip 'n Dale Rescue Rangers
Chip and Dale starred in their own series, Chip 'n Dale Rescue Rangers. They were friends of a famous retiring police dog, whose owner was framed by a crime boss for stealing a ruby. Through the adventure to retrieve the ruby and prove the cop's innocence, they met and recruited Gadget Hackwrench, Monterey Jack, and Zipper, forming the Rescue Rangers officially. They also get new enemies, most notably Fat Cat and Professor Norton Nimnul.

Chip serves as the unspoken leader of the group, while Dale tends to provide most of the comic relief, though Dale does end up becoming the hero at times. Both chipmunks possess a crush on Gadget, becoming rivals for her affections. A running gag in the show has Chip being constantly interrupted when he attempts to tell Gadget his feelings for her. The two have even been love interests themselves. In "Adventures in Squirrelsitting", a squirrel named Tammy falls in love with Chip, and in "Good Times, Bat Times", a bat named Foxglove falls in love with Dale. Both of them apparently don't return these affections.

Mickey Mouse Works
Chip and Dale are recurring characters in Mickey Mouse Works, where they are recast as enemies of Donald Duck once again. One of their most notable appearances in the series is in the short "Mickey's Mixed Nuts", where the chipmunks battle Mickey Mouse (someone that they didn't usually pester in past productions) for the last bag of nuts at a supermarket.

Mickey's Once Upon a Christmas
Chip and Dale appear in the segment Donald Duck: Stuck on Christmas. The two are briefly seen several times throughout the story. In the beginning, they are seen opening their presents. They appear again when they are hit with a snowball by Huey Duck, who then gets hit back by Chip. Their next appearance occurs near the end when an object is thrown into their home and it turns out to be a bag of nuts wrapped as presents from Huey, Dewey, and Louie. In the end, they are last seen throwing away their Christmas decorations and cleaning up.

House of Mouse
Chip and Dale have recurring roles in House of Mouse, primarily as guests at the club. Both chipmunks are seen shaking hands with Donald in the show's intro.

The episode "Chip 'n' Dale" is centered around the chipmunks as they spend their evening stealing bags of nuts from the guests while evading Donald. At the end of the episode, an advertisement is shown in which they seem to have their own storage organization where they store "everything you don't need".

In "Ladies' Night", Minnie hires them to perform an act as the "Chip and Dale Dancers".

In "Ask Von Drake", the chipmunks can be briefly seen during Ludwig Von Drake's headcount of all the Disney character guests.

The duo also appears in "House of Turkey", where Donald complains about how he can't understand what they're saying, only for Daisy to retaliate by saying that she can't understand him either.

They also appear briefly in Mickey's Magical Christmas: Snowed in at the House of Mouse. Right after Pluto's Christmas Tree is shown, Chip and Dale pop out of a small artificial tree and catch Pluto's attention. Pluto starts barking at them, but in a reprise of the closing gag from the preceding short, they slap a "Do not open till Christmas" sticker over his mouth.

Mickey Mouse Clubhouse
Chip and Dale are recurring characters in this computer animated series. They are some of Mickey's friends. Unusually, the two don't seem to have a rivalry with Donald and Pluto. Most of the chipmunks' roles in the series are minor with the exception of the episode "Goofy's Coconutty Monkey", where they are the culprits behind the mysterious disappearance of the jungle's coconuts. In the end, they returned their stash, thinking they were giant nuts. They play another significant role in the episode "Goofy's Thinking Cap" where Mickey, Donald, and Goofy need twelve nuts for Clarabelle's scavenger hunt, to which the chipmunks gladly oblige.

Other versions of the duo also appear; they play the roles of Tweedle Dee and Tweedle Dum in Mickey's Adventures in Wonderland, and in some episodes where Mickey and the gang take a trip to outer space, their "Moon Men" counterparts usually appear, acting as sidekicks to Pete's "Moon Man" counterpart.
