Jill Dozer, simply called Jill and known as Dori Kururi (ドリ・くるり) in Japan, is the cute and pretty heroine of the Game Boy Advance hit Drill Dozer. She is the daughter of Doug, who is the leader of the Red Dozers (a group of thieves). It is said that for years many group of Thieves have been in search for the Red Diamond, which is a powerful diamond that would grant its owner any wish. Luckily Doug’s wife was the person who found it and gifted it to Jill before she died. Though the Red Dozers are a group of thieves, they are kindhearted and only protect the diamond instead of using it for corrupt wishes.
