She is the child lf Pearl and Marina, and Pearl had her inside her. (Say that three times fast.)
She hurt herself badly with a scooter accident. It left a scar that is still visible on her eyebrow.
She likes to annoy her little sister (Alice) a lot.
She helped Marina locate Mike, Peanut, Cuttlefish and Hinata at the Deepsea Metro, but she never saw them IRL.
She also helped her create the Memverse (yes, she's VERY GOOD at programming).
