Disney/Pixar wants the world to know it will premiere a new, full-length trailer for its animated adventure "Finding Dory" on "The Ellen DeGeneres Show" on Wednesday.

To get the word out, the studio posted a 30-second teaser, which has gotten nearly 800,000 views on YouTube since Friday.

The clip features the titular fish voiced by DeGeneres, swimming along to the song "Have You Seen Her?"

"Finding Dory" -- the sequel to 2003's "Finding Nemo" -- is due in theaters June 17.

"'Finding Dory' reunites everyone's favorite forgetful blue tang, Dory, with her friends Nemo and Marlin on a search for answers about her past. What can she remember? Who are her parents? And where did she learn to speak Whale?" a synopsis said.
