Blue x Cricket
Big spoiler warning for The Lost Continent!

Art isn't mine

Possibly my favorite ship in the entire series. Not only does Cricket canonically have a crush on Blue, but IT IS ADORABLE. Literally the first thing she said to him was that his scales were gorgeous and if that ain't the truth-

Ok but really, they're so cute together. I am IN LOVE with the way they trust each other and how Blue defends her tribe, even though they basically tried to enslave him. They care about each other so much and I seriously hope they become a couple by the end of the third arc.
