Her birthday is on December 4.
In the anime
Unlike many other characters from the Tamagotchi P's, Pekopekotchi does not appear in the anime, Tamagotchi! Yume Kira Dream. However, she does appear in Tamagotchi! Miracle Friends as a student in Marutentchi Sensei's designing class, with Miraitchi and Clulutchi.
Pekopekotchi is a white Tamagotchi. She has small and round black eyes with cheek marks on her face. She has a blue "hat" that looks like Chamametchi's, except the ears are floppier. She has a blue dress, with two pompoms on strings at the front.
Pekopeko (ぺこぺこ) is a Japanese word used to describe the sound of someone's tummy when they are hungry.
