1. Kokoa is from Denver (where Toby used to live). But in canon, Kokoa’s family moves from Denver to a more remote area when he grows up (I’d say Nebraska).
2. Kokoa has black eyes.
I'm a little late replying, but Kokoa really loves Scooby-Doo movies. Although he's more of a fan of psychological horror, whether in books, movies, or other media
Yes! He's had a few, men and women. Although Kokoa mostly had short-term relationships that were just about sex... He's bad at dealing with romantic feelings, and he didn't realize that until he started college
