Huey, Dewey, and Louie

Huey (red), Dewey (blue), and Louie (green) are the three nephews of Donald Duck and relatives of Scrooge McDuck. In Kingdom Hearts, they work in the item shop in the First District of Traverse Town. Here, the three take turns selling items. In Kingdom Hearts II, they run an item shop, a weapon shop and an accessory shop in Hollow Bastion. In both endings, they are all seen going back to Disney Castle.

Each wears a long-sleeved turtleneck shirt and baseball cap. Huey's cap and shirt are red, Dewey's are blue, and Louie's are green.

Family

Trivia

 * Strangely, it's not ever shown how Huey, Duey, and Louie ever got to Traverse Town if Disney Castle wasn't destroyed. Plus, it's unknown why they wouldn't be at Disney Castle in Kingdom Hearts II, but instead at Hollow Bastion.
 * Despite being depicted as kids in Kingdom Hearts, the trio still exist ten years in the past (during the events of Kingdom Hearts Birth by Sleep), living in Disney Town. This suggests that they may be older than they look.
