Chip 'n' Dale are a pair of chipmunks who are very popular Disney characters. The duo of chimpmunks reside in the Toon World. 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 nose and two adjacent front teeth, whereas Dale has a larger nose which is alternately brown or red, and a gap between his two front teeth. Chip is also usually the more logical and cunning of the two, with Dale being the more dimwitted one who can be smart at times. The pair are both known for being rivals of Donald Duck and Pluto. They have been known also to be the good friends of Mickey and Minnie.
Chip 'n' Dale began their careers in Private Pluto. In that cartoon, Pluto is a part of the army and runs into trouble when it appears that two nameless chipmunks are hanging around the site in a pillbox. The two would later appear in several of Pluto's cartoons. The chipmunks did not get their names until the short Chip an' Dale. In that short, they meet their new nemesis, Donald Duck. The chipmunks became far more famous for antagonizing Donald and possibly best known for appearing in his shorts.
While they most frequently appeared in theatrically released cartoons under the Donald Duck and Pluto series, they were also featured in three shorts under their own banner, "Chip 'n' Dale." These were Chicken in the Rough, Two Chips and a Miss and The Lone Chipmunks.
