Okay, so what if Yellowtail is an alien, but not a gem. He's the only survivor from another planet the diamonds destroyed like they tried to destroy Earth. I read a theory elsewhere in these comments that he turns into a fish while he's out at sea, and if he's an alien, this could totally be true. It explains why he and Onion talk differently than others. No wonder Onion and Steven are friends. They're both half alien!
