Well, 'feliz cumpleanos' means 'happy birthday' in Spanish. So this graphic novel could center around a birthday - themed plot. It could be about a young person's coming - of - age birthday, with all the challenges and joys that come with growing up, depicted in the unique visual style of a graphic novel.
I have no clear understanding of these words. 'Aguacate' is a Spanish word for avocado, but 'caricatura pepa' seems quite unusual and might be something specific to a particular context or made-up. Without more context, it's hard to say exactly what they mean or how they relate.
I'm not entirely sure as 'feliz naviad' seems like a misspelling. If it's supposed to be 'feliz navidad' which means 'Merry Christmas' in Spanish, the back story could be related to the origin of Christmas traditions in Spanish - speaking cultures. It might involve things like the celebration of the birth of Jesus, the coming together of families, and the various festive customs like having a big dinner, giving gifts, and decorating Christmas trees.
Since we don't know much about this 'feliz cumpleanos graphic novel', the main characters could be a diverse group. Maybe there's a creative artist who wants to make their birthday extra special and their friends who help them plan an amazing celebration. Or it could be a family - centered story where the main characters are parents, children, and grandparents all involved in a big birthday bash.
I'm not familiar with 'feliz naviad' exactly. It could be a very specific or local story. Maybe it's a new term someone created for their own Christmas - related story. If it was 'feliz navidad', then there are so many aspects to the back story. There are the religious roots, the cultural traditions of different regions in Spanish - speaking countries. But for 'feliz naviad', more information is needed to really explain the back story.
