>>53769590I like Towa's Bibi, from lore to stark colorscheme to the fact that he morphs into wearable merch but I recognize that Sora's nun-nun is prime.
You might think it boring, but I see it as the prototypical holo mascot: a cute simple shape with a face.
Nun-nuns are the starting point of all holomascots.
Burying a nun-nun in a veggie garden morphs it into a nekko or sapling. Feed it carrots and it sprouts ears and is a nousagi. Throw it in the ocean? Takodachi. Send it through a hell portal and back - Bibi. Keep it in mud and feed it scraps, love and abuse in equal measure? Haaton. Radiation leak? Fubuzilla. Feed it a blood and acerola juice mix? It fucking dies and its tortured soul returns as a kapumin/Obake-chan.
Sometimes simple is best, as it leaves so much room for possibility. You can imprint whatever emotion you want onto its placid face, and they're all appropriate.
