Professor Ivy's assistants, also known collectively as the triplets (Japanese: ウチキド博士の助手の三つ子 Dr. Uchikido's triplet assistants), are three women and characters of the day who live with Professor Ivy on Valencia Island and assist her with her research work. Individually, their names are (Japanese: ミナミ Minami), (Japanese: ツナミ Tsunami), and Faith (Japanese: コナミ Konami). Their individual English names were mentioned only in books. The triplets appeared in Poké Ball Peril (EP085). Though they are useful with their assistance, the three women are not particularly good at domestic duties. Their need for someone to handle the cooking and cleaning around the house reminded Brock of his family, which is one reason why he stayed behind as an assistant for Professor Ivy instead of traveling with Ash through the Orange Islands. They reappeared in a flashback in A Tent Situation (EP117). (Source: Bulbapedia)
