But Sunni and Calla's interactions in the show scream "we're feeling something that could be romantic but we're currently too young/too embedded in a world where queer people aren't around to know that" right?

Like every episode that they're together they're like two magnetic needles pointing right at each other?

And it's not the usual girl best friends that you find in most kids cartoons. There's no times where they fight over boys affections, no times they're envious (besides Sunni generally wanting to be a princess) of each other, at best there's one episode where they get shitty at each other but like they get over it real fast.

Sure Sunni is supposed to like Gusto (but like, I really think it's mostly that Gusto is the only bear in his like 20's she's ever met and the only one she doesn't immediately think of as Family).

Sunni having a crush on gusto is honestly fine, and as you said makes sense since hes the first non family member in her life + the attention is nice, shes a kid with her first celebrity crush <3

The premise is that Gusto sees Cubbi being gently adamonished by Gruffi and Grammi about breaking rules, and Gusto is like: "Kid, a Gummi Bear shouldn't be limited by rules! It's about being free spirit!" So Grammi gets the idea for Cubbi to have a sleepover at Gusto's place. And Gusto is like: "Sure, that will be fine!" At first he's all laid-back and "there are no rules here, man!", but slowly Cubbi gets tiresome and disastrous, and Gusto starts to enforce rules.

It also culminates with him saying: "This time Grampy Gruffi may be right." Gusto is supposed to be a free spirit, still part of the community (since he often participates in talks about various issues), but living on his own and liking his freedom "without rules". But Cubbi's presence disturbs this freedom and makes Gusto realize that some rules have to be enforced so the cohabitation could be more bearable.
