Greetings I'm Zaida. Here to help. You can be human, or animal. Hell, a splatoon character seems fine in the community.
However if you don't want to stay a splatoon I do have a suggestion~ Get an animal, right? And mix with a squid, ok?
(Example: a doggy and squid. A Squiggy. It's a dog with squid ears and tail «like splatoon character hair», has squid eyes, an inky tongue, bright coat~) something like that. I don't know it would look cool to see an animal mixed with a squid in my opinion.
