Mametchi まめっち

Mametchi is a male adult-stage Tamagotchi who debuted on the original Tamagotchi, and has appeared on nearly every release since, serving as the main mascot of the franchise. Mametchi is a member of the Mame Family and his birthday is November 23, the same date as the release of the first Tamagotchi. On almost every Tamagotchi model, he is the healthiest adult character, obtained by perfect care.

In Tamagotchi! Yume Kira Dream:

He can make anything in a short time, but can fail. Mametchi is tone deaf and sings horribly without the Melody Charm.
