Young Mimitchi looks like a smaller version of Mimitchi but with lighter blue ears, and prior to the Entama it was not depicted with a tail. In the anime and Tamagotchi: Party On!, she is depicted with pink ears (occasionally in the Wii game, because the lighter-blue-eared one is usually there).
She is a huge admirer of Mimitchi and can always be found diligently working on her arithmetic skills. She is sincere and a good mathematician; math is her favorite study subject. She is practical and already has big plans for her life. She is very serious, but sometimes has scatterbrained moments.
She always says, "I wanna be a grown-up like Mimitchi!"
