Octavius Rex, also known as Long, Tan, and Handsome, is Pearl's ex-boyfriend, who first appears in the episode "The Chaperone." He later returns in the season 9 episode "Goodbye, Krabby Patty?" and begins to make more recurring appearances.
Octavius appears alongside Maestro Mackerel at the concert hall. At first, Maestro does not know who is on the stage, but Octavius tells him it is Squidward and that he is a clarinet player. At first he enjoys watching him play the clarinet, but once Squidward wakes up he hates it.
Octavius is one of the customers in the Krusty Krab who orders the Krabby Soup. Sunshine emerges from the soup bowl and kisses him, causing his wife, Debbie, to hit him, complaining that he loves his soup more than her.
When Octavius is served his food on weights, he cannot lift them. Larry and Frank yell at him to push the weights, so he does, and manages to lift them onto a table. However, he passes out before he can eat.
After the events of "The Chaperone," Octavius married Debbie. In "There's a Sponge in My Soup," when he is kissed by Sunshine, who is in his soup, Debbie hits him and complains that he loves his soup more than her.
