Watch: The Final Finding Dory Trailer

We're just over three weeks away from heading back to the ocean with one of the most friendly (and forgetful) fish in the sea.

The latest trailer for what will most likely be one of the biggest films of the summer shows Dory getting hauled off to a marine rehabilitation center after she's found with litter stuck to her while searching for her family.

We also learn that Nemo has questionable taste in friends (hi, Becky), Dory seems right at home in a center full of misfits, and that Idris Elba, for the third time this year, will lend his voice to an animated animal, this time a sea lion named Fluke. Watch below.
