I strongly suspect "Nu, Pogodi!", Nintendo's "Mickey Mouse" and Nintendo's "Egg" all use the same mcu code, but have different lcd screens and bezels.
Nintendo had to change the lcd and branding of "Mickey Mouse" to "Egg" in countries where they did not have a license to the Disney characters. "Nu, Pogodi!" was an unlicensed die clone, but with the lcd characters switched to resemble those of the soviet(later russian) cartoon.
