Pixar/Disney will return under the sea next year for more adventures with clown fish, a blue tang, sharks and sting rays in "Finding Dory." While fans will have to "just keep swimming" until June 2016, the first trailer to the highly anticipated sequel to "Finding Nemo" (2003) was released by "The Ellen DeGeneres Show" Tuesday.

The trailer clocks in at one minute and 42 seconds long, but there are a few things that could've gone unnoticed if you weren't watching closely. Here are four moments you might have missed from the first "Finding Dory" trailer:

1. "Don't Cry, Mommy": The trailer begins with Dory (Ellen DeGeneres) talking in her sleep in the middle of the night. She's shown telling her mother not to cry. Is this some sort of bad family memory or maybe the day Dory went off on her own? Possibly, but then she mentions something about a ratchet wrench and fixing something, so maybe her mother was crying over something broken.

2. Dory Remembered Something: The forgetful fish may have actually remembered something from her past. "Is it like a picture in your head? And then you think I've seen this before. I just used the word before which means I'm remembering something!" Dory yells with excitement. However, the moment looks like it might be short lived as she asks Nemo (Hayden Rolence) what she was just talking about.

3. Mr. Ray Is Back: Looks like Mr. Ray (Bob Peterson) along with the rest of Nemo's class look will all be back for the sequel. Mr. Ray was Nemo's teacher  who carried the class around on his back and taught them about all the other creatures under the sea. What will Mr. Ray and the rest of the class learn in "Finding Dory"? Will Dory have a part in the class or get help in her search from the students?

4. Finding Dory's Family: The adventure Dory, Marlin (Albert Brooks) and Nemo will find themselves on is the mission to find Dory's family, who are somewhere in the ocean. Their new mission might be a little difficult with Dory's tendency to forget things. The trailer comes to a close with Dory saying she remembered something important. She tries guessing what it is and turns to Marlin for help.

"Something about a clam? No an oyster?" Dory asks. Marlin replies with several no's.
