Chip and Dale

Chip and Dale are a pair of chipmunks. They reside in Disney Castle as operators of the Gummi Ship, and appear in Kingdom Hearts and Kingdom Hearts II. They are almost identical but can be identified easily—Chip has a black nose and one bucked tooth, while Dale has a red nose, two bucked teeth, and scruffy hair on the top of his head. Chip and Dale are voiced by veteran voice talents Tress MacNeille and Corey Burton, respectively; the two had previously done voicework for the duo in the TV series Chip & Dale: Rescue Rangers.

Kingdom Hearts Birth by Sleep
Chip and Dale appeared in Disney Town hearing the conversation between Terra and Queen Minnie. They tell Terra that Pete is playing unfairly in the Raceway game and ask him to help. After Terra wins and beats Pete, they both offer their votes to Terra, in hopes that he would win the Dream Festival.

Kingdom Hearts
Chip and Dale have limited roles in the first game, appearing briefly at the start of the game to send Donald, Goofy and Pluto off to Traverse Town. They announce events like when a new competition is being held at Olympus Coliseum.

Kingdom Hearts II
Kingdom Hearts II gives the two chipmunks a larger role than the first game. They appear in Disney Castle, warning the visitors of the invasion of Heartless in the castle, and are present to witness the salvation of it after Merlin sent the trio back in time to prevent the past from changing. They also contact the trio when a strange universal reading appears in their radar, eventually the reading is turned out to be the World That Never Was. They are also present when Mickey Mouse, Donald Duck, Goofy, Scrooge McDuck, Pluto, Jiminy Cricket and Donald's nephews return to the castle together.

Kingdom Hearts coded
Both Chip and Dale appear in this game, alongside King Mickey, Donald, Goofy and Jiminy Cricket at Disney Castle. They both are the engineers of the computer. When Donald, Mickey, Goofy and Pete were sucked into the data world, Chip and Dale remain behind and try to contact them, but are blocked by the signals.

Appearance
Chip and Dale are anthropomorphized chipmunks, and as such are very small, to the point that in Kingdom Hearts II they are small enough to be covered by the "Talk" reaction command prompt. The duo are similar in appearance, though with several small differences.

Chip has brown fur over most of his body, excluding the fur on his face, neck, the front of his belly, and around his eyes, which is buff-colored. He has triangular ears on top of his head, a white mouth, and a black nose. Chip has three toes on each foot and four fingers on each hand. He wears seal brown gloves, each with a gold, horizontal line near the bottom. Chip also wears an apron of sorts with red shoulder straps secured to black buttons, while the apron itself is yellow with an outline of the same color as his fur. The yellow section sports green stitching lining the edge, and the other section has brown stitching. There is a slanted, blue pocket on the front of the apron with a red Mickey symbol surrounded by a yellow gear. He also has two teeth, set together, in the center of his upper jaw.

Dale shares most of his physical features with his brother, but he has two, bucked teeth in his top jaw, a larger, red nose, slightly lighter-colored fur, and, in Kingdom Hearts Birth by Sleep, a mohawk-like crest of fur on the top of his head. Unlike Chip's ears, which face roughly forward, Dale's point in opposite directions, to the left and right. His gloves are also a lighter shade than Chip's, and his apron has the inverse color scheme of Chip's; that is, the yellow section on Dale's apron is buff-colored, and vice-versa, the same being true for the two different stitching colors on the apron.

Origin
Chip and Dale first appear in an animated short called Private Pluto. In the short, Pluto acts as a guard dog who guards a pill-box only until the two chipmunks torment Pluto and cause a classic war of wit.
