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 "Goodbye, Krabby Patty?" and begins to make more recurring cameo appearances.
He is a skinny, maple brown anchovy who wears a light green sweater with brown pants and large round black glasses. He has a large visible bald spot on his head.
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.
"There's a Sponge in My Soup"
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, Gale, to hit him, complaining that he loves his soup more than her.
"Larry the Floor Manager"
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.
"Stuck on the Roof"
When SpongeBob is stuck on the Krusty Krab roof, Sandy tries to get him down using her Extend-O-Boots. However, she loses control of the invention and nearly kicks Octavius and other Bikini Bottomites, who run away screaming.
"Gary's Got Legs"
Octavius is one of the people at the Snail Park who are shocked at Gary's pair of legs, and is later seen flying through the air after Gary kicks him.
"The Goofy Newbie"
He appears as an employee at Goofy Goober's Ice Cream Party Boat along with his co-worker, constantly mentioning that Goofy Goober employees get free ice cream all day long, giving Patrick the idea to get a job at Goofy Goober's.
They dated for a while, but then Octavius broke up with her.
He then tries to talk to her at the prom in "The Chaperone," but Pearl rejects him.
After the events of "The Chaperone," Octavius marries 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.
Starting with "Mutiny on the Krusty," he no longer says "meep" and now speaks in full sentences.
