The Tamagotchi iD L marks her only appearance to date, as she has not yet appeared on any release since.
Momoirotchi resembles a pink, cartoon-like parcel with a large ribbon on top of her head. Her face is a lighter pink than her body. She has small black eyes and pink cheeks. Like most baby Tamagotchis, she doesn't have arms or legs.
"Momoiro" is the Japanese word for "pink", which describes Momoirotchi's color.
