Garold Wilson "Gary" Snail Jr. (Tom Kenny/Dee Bradley Baker when he actually speaks) is SpongeBob's pet sea snail. Within the series, snails are analogous to cats, so Gary almost always vocalizes like a feline.^[6] Despite this, other characters can understand and

communicate with him. Depicted as a level-headed character, Gary sometimes serves as a voice of reason for SpongeBob, and solves problems that his owner cannot. He is sometimes nicknamed "Gare-Bear" by SpongeBob, and it is revealed in "A Pal for Gary" that his full first name is Garold.

Mrs. Puff is a pufferfish with blonde hair, who is the owner and teacher of a boating school (analogous to driving school, as the "boats" are underwater equivalents to cars).

due to his inability to drive without crashing. In the episode "Krusty Love", it is revealed that her husband is dead and was turned by humans into a lamp. As a running gag, she frequently gets in trouble with the police due to SpongeBob's inability to drive without causing public damage.

Pearl Krabs (Lori Alan) is Mr. Krabs' teenage sperm whale daughter. The series has yet to explain their disparity in species, although in the book SpongeBob's Trivia Book, Mr. Krabs explains that Pearl takes after her mother, meaning her mother was

apparently also a whale. Occasionally in the series, Mr. Krabs will exclaim, " Mother of Pearl!" possibly referencing her mother. Her mother is never seen nor addressed in the series (Krabs is portrayed in the series as being a single man). Pearl is frequently embarrassed by her father's cheap attitude and often forces him to try and change his habits

Karen (Jill Talley) is Plankton's nagging computer "WIFE" (as in an acronym for "Wired Integrated Female Electroencephalograph") and voice of reason.

formula, although on occasions Plankton rejects her ideas and then takes them as if they were his own. She has a sarcastic attitude towards Plankton, and it is revealed in The SpongeBob SquarePants Movie that she never agreed to marry Plankton. Karen also made a cameo in an episode of The Fairly OddParents called "Love Triangle," in which Karen is the monitor at the hospital after Foop catches a disease.

It is most likely that they are parodies ofAquaman and Aqualad, but since their younger selves are voiced by Adam West and Burt Ward, and because they use onomatopoeic words similar to those in

the 1960s Batman TV series, they also parody Batman and Robin. Mermaid Man is known for completely forgetting things, yelling a prolonged "EVIL!" whenever he hears the word, and Barnacle Boy seems to be the smarter, more sensible of the two. It was revealed in the episode entitled "Mermaid Man Begins" of the 8th season that Mermaid Man's given name is Ernie, likely an homage to his voice actor. In this same episode, Barnacle Boy was referred to as Tim, but in a previous season, he was called Kyle. Coincidentally, Borgnine and Conway previously appeared together on the 1960s TV seriesMcHale's Navy. Borgnine died on July 8, 2012 and since late 2012, Mermaid Man has been voiced by Joe Whyte, who voiced Mr. Krabs in some video games.

Larry the Lobster (Mr. Lawrence) is a lobster lifeguard of the Goo Lagoon. Larry

is a bodybuilder and workout fanatic. He was considered a lifeguard on "SpongeGuard on Duty", but in other episodes, he is not and simply just hangs out at the beach. Despite his large and muscular physique, he is sometimes shown to be somewhat of a coward.

 (Stephen Hillenburg and Paul Tibbitt) is the Patchy the Pirate's "annoying" pet parrot. Potty is a crudely made puppet controlled by very obvious strings. He is obnoxious and often annoys or talks back to Patchy. He is similar to Iago fromAladdin and Zazu from the Lion King.
