Shellsea is very independent, focused and always speaks her mind, and can be mean. She also seems to dislike Oscar. She is a fashion diva and when Bea is not hanging out with Milo and Oscar, she always makes time for her friends. Like Bea, Shellsea has interest in the drama club. Shellsea enjoys dancing and listening to hot tunes. She also enjoys putting on makeup or lipstick from her white purse.
She had her most major role when Bea was about to do a girls party. Shellsea was bringing cupcakes. When Milo wanted to go to the party, Shellsea told him that sometimes girls like to get together and have fun. When Milo still begged, Shellsea said she's watching him, with her fish eyes. Shellsea and the girls went to Bea's party and when Clamantha suggested to paint her nails, Shellsea pointed out that none of them has nails. When Milo and Oscar came disguised as girls, Shellsea thought they looked ugly. Bea and Shellsea noticed it was Milo and Oscar the first time they saw them in their costumes. Shellsea thought they were spying on them and instead of Bea telling Milo and Oscar to leave, Shellsea tells her that since they are trying to ruin their party, they should ruin theirs. At first Bea disagrees, but later does it. Bea and Shellsea then tortured them and sang Eat Dip. When Oscar admits they're boys, Bea says they already knew. Milo and Oscar told Bea that they thought they were gonna lose her and Shellsea said that who knew boys could be so sweet when they told them they got through all of that for Bea.
Bea and Shellsea are the best of friends. Shellsea gives her tips or advice and is seen with Bea everywhere, except when Bea is having an adventure with Milo or Oscar. They both have a lot in common and Shellsea is always there for Bea when she needs her. Shellsea also helped Bea when she tried to be "queen of the dance" by calling her to the Student Council's and letting her see herself with her mirror ("Queen Bea"). Shellsea and Bea usually talk about dating, boys and "girl stuff". Shellsea gave Bea the shoulder pads, shoes and makeup to make her look like an adult ("Bea Becomes an Adult Fish").They are like sisters
Shellsea knows Milo, but doesn't hang out with him much. But since Milo is Bea's friend, Shellsea may be just "friends" with him, though Shellsea tortured them for sneaking to their party ("Fish Sleepover Party"). Shellsea was part of the Fishgiving play to help Milo study, but didn't succeed ("Fail Fish"). Like the other students, Shellsea enjoyed Milo's entrance in the class with the eel ("Fish Out of Water").
Like Milo, Oscar and Shellsea's relationship is unknown. She suggested torturing him along with Milo for breaking into the party ("Fish Sleepover Party"). But Shellsea liked Oscar's sense of humor ("Funny Fish") and "aww'ed" when he told Bea he'd miss her ("Bea Becomes an Adult Fish"). Also, Oscar mentions that Shellsea talks about him behind his back ("Halloween Haul"). Shellsea got paired up with Oscar for a project ("Fuddy Duddy Study Buddy")
