Clamantha's Opinion of Oscar
Clamantha has an obsession with Oscar, almost to insanity. Clamantha thinks Oscar is "hot", which terrifies him. Oscar's thinking of Clamantha is that she is a good person with a heart of gold, but is still very creeped out/afraid of her and doesn't like the fact that she always invading his personal space. Clamantha has a locker that has a shrine dedicated to Oscar, and dressed up as Oscar's imaginary girlfriend, Doris Flores Gorgeous to get a kiss from him. She even tried to disguise as various different people or things, even Steve Jackson to be roomies with Oscar. She also even wrote a song about Oscar in her band. Even her 5 digit password is "Oscar". The Clamantha look-like liked Ron instead of Oscar, and even kissed him, but Oscar didn't mind that ("The Tale of Sir Oscar Fish"). Oscar atempted to trick her into dating his laptop, to which after it ran out of battery and wouldn't talk to her, he cheered her up and didn't say that "Webster" was a laptop but a jerk. She later attempted to kiss him causing him to scream again and start running away ("Two Clams in Love").
Oscar's Opinion of Clamantha
Oscar is sort of terrified of Clamantha, partly because she has a crush on him. During his "fake date" with Clamantha, she drove him to Lover's Tank and he was stuck with her until Bea and Milo rescued him. Bea pretended to be Oscar's girlfriend so that Clamantha would leave ("Bea Stays in the Picture"). One time he convinced her that his laptop (that had two web cams on it) was another clam named Webster by typing in conversations from his computer for it to have with Clamantha (via a computerized voice), eventually "Webster" ran out of battery causing her to believe that Webster hated her and dumped her. Oscar (who was the only one she would let talk to her) ended up going to her room and cheering her up by telling her that she had a heart of gold and was a good person; meaning that he does care for her to an extent despite being very scared of her ("Two Clams in Love"). Bea at one point noted that she used to think Clamantha's crush on Oscar was cute but now just sad, meaning that Clamantha's feelings for Oscar have gone on for a while.
