Nazotchi serves as a placeholder character between different Tamagotchi releases; if the character on one does not exist on another or the difference in the programming between the two of them prevents a proper character from appearing.
Nazotchi appears as a big black ball wearing a wide, red hat, and two eyes visible from under the brim. It has two arms and legs, and is often depicted carrying a bindle. Nazotchi has neither a specific gender nor an Ura counterpart.
Since Nazotchi is an "unknown" character, it can have any forms of personality and age, but is is usually described as a quiet and elusive Tamagotchi. One of the many Nazotchis is the postman of Tamagotchi Town, delivering mail, paychecks, newspapers, presents, and fortunes to Tamagotchis daily.
In the game, Tamagotchi Corner Shop 3, it is stated that not much is known about him/her, but is also good with riddles.
One of the Nazotchi's primary function on the Music Star is his original interpretation of being a postman, appearing at the door several times a day to deliver presents from the Gotchi King (or a parent from the previous generation, from the second generation onward) and letters from fans, which may either be a heart, star, or poop.
As the Tamagotchi Music Star is compatable with the Family pets, Nazotchi appears as a character placeholder. The two can breed by sending one Family character over to the Music Star; the character will be rendered as Nazotchi.

Nazotchi appears on the Tama-Go as the shopkeeper and when you connect a lower version with the Tama-Go, instead of the character, a Nazotchi will appear on the Friends list.
