Chip and Dale

Chip & Dale are a pair of chipmunks. They reside in Disney Castle as operators of the Gummi Ships. They are almost identical but can be identified easily - Chip has a black nose, while Dale has a red nose and bucked teeth.

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. They are seen during the end credits with Queen Minnie and Daisy.

Kingdom Hearts II
Kingdom Hearts II gives the two chipmunks a larger role than the first game. This time, they accompany Sora, Donald and Goofy around to different worlds in two miniature Gummi Ships that fly alongside the actual Gummi Ship. They also appear in Disney Castle, warning the visitors of the invasion of Heartless in the castle.
