Mimitchi
From Tamagotchi Wikia
Mimitchi (みみっち) is a Tamagotchi character first seen on P2 original Tamagotchi, and has appeared on many modern releases since.
Personality
In the official Tam comic, she has a bit of a speech impediment: she adds the word "pyong" to the end of every sentence. "Pyong" isn't quite translatable; technically speaking it's a sound effect, somewhat like "boing", but in this case Mimichi actually says it out loud. When she gets angry, she bares her little fangs and snarls at people; quite scary, really.
In the anime and film, Mimitchi appears as a background character, in Mametchi's class.
Other Forms
YoungMimitchi
YoungMimitchi ('やんぐみみっち YanguMimitchi) is a teen form of Mimitchi introduced with the Tamagotchi Connection.
YoungMimitchi adores Mimitchi. She is sincere and a good mathematician; math is her favorite study subject. YoungMimitchi is also impatient; she can't wait to become an adult.
