Gary the Snail

Garold "Gary" Wilson, Jr. is SpongeBob SquarePants' pet sea snail and the most commonly seen pet in the series. He lives with SpongeBob in his pineapple house on 124 Conch Street. Gary is voiced by Tom Kenny and first appears in the pilot episode, "Help Wanted."

He is a domesticated house pet with similar mannerisms to the real-world cat, most notably his "meow" sound, as snails are the underwater equivalent to cats in the show, he also has the abilities of dogs from fetching to doing tricks. It has been suggested that SpongeBob has had Gary ever since he was a young boy. The episode "Treats!" reveals that Gary was adopted by SpongeBob. In "Plankton's Pet," SpongeBob reveals to have bought Gary at the animal shelter.
