Mametchi

Mametchi is a member of the Mame family, born on November 23rd, the same day the first Tamagotchi was released. In almost all Tamagotchi models, he is the healthiest adult character, a result of impeccable care.
Mametchi is light yellow in color, with a wide, round head, a narrow body, and large black eyes. He has two arms, two legs, and two large bumps on top of his head, resembling animal ears, covered in black fur. He has rosy cheeks and dark blue eyes.
Mametchi is a very healthy adult Tamagotchi, likely destined for a long life. He is extremely intelligent, with an IQ of around 250. He is a true child prodigy and one of the smartest Tamagotchis. He always speaks very politely, almost formally, even to his closest friends. His hobby is creating inventions, and although they sometimes fail, he continues to create them. He is not very good at painting or singing, as he is practically tone-deaf.
