This inventive animated comedy series, set inside a giant fish tank in Bud's Pet Shop, presents high school life as seen through the eyes of three BFFs (best fish friends), Bea, Milo and Oscar. Together they experience the typical life challenges and triumphs, including friendship, dating and sports, along with more atypical situations such as giant lobster attacks and, with the use of special land suits, school field trips to the hamster cages. The series was created by children's book illustrator Noah Z. Jones and features a notable voice cast. It's produced using an innovative mixture of digital animation and photo collage
Bea decides to take a job at Fish Flakes but soon misses her old carefree life, but no one will let her quit. Meanwhile, Milo and Oscar get sent to daycare after being mistaken of being Bea's babies. Oscar dislikes the babies, but Milo wears a diaper and stays nearby.
Milo and Bea get a dog named Murphy, who Oscar doesn't like. Oscar ends up yelling at the dog and as a result the dog runs away. Now Bea, Milo, and Oscar will have to go and find Murphy.
When the school homecoming dance is coming up, Bea must be chosen to be Homecoming Queen. But her "embarrassing" parents have signed up to be chaperones. So Milo and Oscar help plan a fake school dance to stop them from ruining Bea's chance at becoming queen.
Bea and Oscar help Milo study for his final exam so he doesn't get held back a grade like their old friend Kevin. To do this, they must find Milo's un-traditional way of learning.
Oscar seems to be the only one without a good sense of humour, so Milo and Bea tell Oscar to just pretend everything's funny. But he goes too far.
Oscar and Milo believe that their teacher Mr. Baldwin lives a double life as a comic book superhero and Bea, who needs to do a report for Dr. Frog's class. He tells Bea that they have to get proof.
