Our beloved aquatic creatures return! Disney has released the first trailer and poster for Pixar’s upcoming film Finding Dory, it is a sequel to Finding Nemo. The sequel will be released 13 years after Finding Nemo, but the story itself picks up only six months after the events from the first film when Dory suddenly starts to remember certain things about her life. In the trailer, these memories first start to manifest themselves in her sleep, and she starts sleep swimming.

The story follows Dory as she embarks on a journey to find her mom and dad. This leads her to an ocean sanctuary facility where wounded animals are treated before they are re-released into the wild. It’s here that she meets lots of new characters like an octopus, who is missing a leg, and a beluga whale named Bailey, who thinks he has suffered a head injury because of the big bump on his head that is supposed to be there.

Ellen DeGeneres and Albert Brooks will reprise their roles of Dory and Marlin, and they are joined by the voice cast that includes Ed O’Neill as an octopus named Hank; Ty Burrell as the beluga whale (we sense a strong hint of Modern Family), named Destiny; Kaitlin Olsen as a “kind-hearted whale shark”, and Diane Keaton and Eugene Levy as Dory’s parents.

Andrew Stanton returns to direct the film, which hits theaters June 17th, 2016. Check out the trailer:
