Story

Ruby Gillman (voice of Lana Condor) is just like any other awkward 15-year-old girl. She’s trying to fit in at her school, Oceanside High, and is very self-conscious about how she looks. But the problem is that Ruby isn’t a girl – she’s a kraken, a fish-like creature with tentacles, trying to be a human.

Ruby lives with her overprotective mother, Agatha (Toni Collette), father, Arthur (Colman Domingo), and brother, Sam (Blue Chapman). When her parents say that Ruby can’t go to the beach to celebrate the end of the year with her friends, she goes anyway. There she meets Connor (Jaboukie Young-White), a boy she has a crush on. Ruby inadvertently fires a romantic bubble shooter, which sends Connor flying into the ocean. Ruby is scared of the water, as she has always been told not to go into it, but she overcomes her fear and dives in.

Scared she’ll die, Ruby discovers she can breathe underwater and then turns into a beautiful, sylph-like creature with long tentacles. She saves Connor, who is unconscious in the water, and returns to land. To her horror, Ruby starts to grow into a giant creature. Agatha comes to her rescue, and Ruby learns of her true identity – she’s the granddaughter of the Warrior Queen of the Seven Seas and protector of the oceans. Ruby also learns how her mother had fled the ocean after winning a battle with the mermaids and then locked away a powerful trident.

Naïve and kind by nature, Ruby has much to learn about her new identity and many challenges ahead. She comes to accept who she is and what she must do to protect the oceans.
