Bea, one of the three fish BFF's including Milo and Oscar at Fresh Water High, freaks out literally when her annual school photo is taken, for she claimed that it was taken badly. In the attempt to bring it back fearing that her expected future as an actor would be in jeopardy by a single bad picture, she distracts her friend and school photo editor Pirahnica, who claims to be in love with Oscar, by making the poor fellow take her on a date. After avoiding dangerous obstacles set by Pirahnica, Bea and Milo find the pictures as they see Bea's taken one. Milo discovers that there was nothing wrong with it. Bea had known that, but she thought that her look wasn't suited for an actor. After Milo talked some sense into Bea by proclaiming that she was perfect the way she was, she suddenly remembers Oscar and stops his nightmare with Pirahnica by stating that she and Oscar were dating. After the nutty clam left, Oscar was happy that Bea felt the same love he felt for her, only to figure out that she was acting.

Bea has a girl sleepover party and Milo and Oscar feel left out, so attend the party as Milina and Oscerlisabeth. Chelsea and Bea let the other girls know that they are Milo and Oscar. But instead of confronting them, the girls then make them do what girls really do on sleepover parties.

Milo ventures out of the fish tank alone, so Bea and Oscar follow him. The three best friends catch the eye of the pet store cat Wilfred, and Milo must put aside his differences with the others to save the day.

When Bea goes on several dates and Milo gets a date, Oscar feels he is the only one without a girl so and pretends to have a girlfriend named Doris Flores Gorgeous, but he struggles to keep it a secret from Milo and Bea. He tells Milo and Bea that Doris lives in Fish Niagara Falls so the friends try to "cheer up" Oscar by taking him there. When they get there, there actually is Doris who turned out to be Clamantha.

Milo tries to follow his dream by playing on the Football team but gets the job of Water Boy. Little does he realize the importance of his job, since the football team is playing at the Gecko tank.
