You can't forget her, and her enthusiasm is just as enduring as her signature chant: "Just keep swimming, just keep swimming..."

That's right, the first trailer for "Finding Dory," the spin-off sequel film for the beloved 2003 "Finding Nemo," is finally here.

As the title would imply, the movie focuses on dopey blue tang fish friend Dory, voiced by Ellen DeGeneres. She reunites with her fish pals and goes on a quest for answers about her past and her family, and we're full to the gills with emotion in anticipation. If you shed a tear during the original "Finding Nemo," our bet is that you'll be crying a whole ocean of them once you've seen this latest Pixar creation, which will probably make you want to call your parents and tell them you love them after seeing it.

Here's our first look at the trailer, via EllenTube:

We also got our first look at the poster for the movie, bearing the tagline "She just kept swimming."

"Finding Dory" swims into theaters June 17, 2016.
