Tim[citation needed], better known by his superhero name Barnacle Boy,[1] is the sidekick of Mermaid Man. He is a superhero and a parody of both Aqualad and Robin. He is said to be 68 years old.[2] He first appears in "Mermaid Man and Barnacle Boy." He and Mermaid Man are now retired from the series ever since Ernest Borgnine's death in 2012. However they stll make many cameos throughout the show. His voice actor, Tim Conway, passed away in 2019.


Barnacle Boy is tall, thin, bald, has a very large nose, puffy ears, wears a sailor hat, a black mask, and a turquoise neckerchief. As an older man, he bears a slight resemblance to Squidward. He also wears dark blue rubber gloves, boots, a red T-shirt, and rubber black shorts. As the younger of the duo, he is more sane and self-aware than Mermaid Man. However, Barnacle Boy is also more cranky. He often calls Mermaid Man an "old coot." He is revealed to be 68 years old in "Mermaid Man and Barnacle Boy V." As his younger self, instead of a black mask, he wears glasses and is much taller. Also, as his younger self, his neckerchief is space-control. His nose is also smaller.

Barnacle Boy possesses powers similar to Mermaid Man, though he lacks the belt powers. Barnacle Boy also has "Sulfur Vision" - a form of heat vision - which Mermaid Man has never been shown to have. Like Mermaid Man, his powers do not work as well as they used to, mostly due to old age.

Despite being a senior citizen, Barnacle Boy is still treated like a child by his mentor, much to his disdain. In "Mermaid Man and Barnacle Boy V," when Mermaid Man orders a Pipsqueak Patty (a very small version of a Krabby Patty intended for children) for Barnacle Boy at the Krusty Krab, they get into an argument, which ultimately results in Barnacle Boy becoming a villain and forming a group called "E.V.I.L." (Every Villain Is Lemons) with Man Ray and the Dirty Bubble. After a protracted fight with Mermaid Man and the "International Justice League of Super Acquaintances" which E.V.I.L. actually wins, he and Mermaid Man patch things up. Barnacle Man (as he prefers to be called) gets a little more respect now.

Mermaid Man and Barnacle Boy appear during a new episode being directed by Gill Hammerstein. In it, the duo is falsely accused of destroying the Sand Stadium when it was actually stolen by the Sneaky Hermit. However, when they are sent to Bikini Bottom Jail, the prison warden tells them what is really happening and frees them so they can catch the villain, thus accidentally letting the Dirty Bubble and Man Ray go free.

Mermaid Man and Barnacle Boy go to Goo Lagoon and the Krusty Krab to find clues. When they go to the Chum Bucket, they discover that Man Ray and the Dirty Bubble are using the mayor's child as their captive in an attempt to help the Sneaky Hermit's plans. They reluctantly make a truce with the villains and work together to find the Sneaky Hermit with some help from an expert hunter from Jellyfish Fields.

They manage to track down the hermit and foil his plan of putting Bikini Bottom on his back so he can have a home. When the crisis ends, they return to the Sand Stadium to continue to watch the musical performance.
