Mimmie (ミミー, Mimmy in Mother) is a character in EarthBound Beginnings. She is the sister of Ninten and her twin Minnie. At the beginning of the game, she is attacked by a doll when the poltergeist upsets Ninten's house. After the house is calm once again, Mimmie will give Ninten some Orange Juice everytime he talks to her. Until he leaves the house. After that she stays in her room and if talked to says "No, I'm not Minnie, I'm Mimmie"
The Mother Encyclopedia says that Minnie and Mimmie were born when Ninten was 5. Being that Ninten is stated to be 12, that makes Minnie and Mimmie 7.
