Doraemon - Season 1

DESCRIPTION

Suneo has a part in a TV show and the others are jealous. Doraemon produces a ray which allows Nobita to be the main character in a story, TV show or anywhere else, and while Suneo just turns out to be one in a crowd, Nobita gets to be the lead in the show (he has Nobita's face, voice, etc.).
