Gary the Snail is one of the main characters and is the pet snail to SpongeBob SquarePants and a cousin to Patrick Star. He is the equivalent of a cat as, snails are cats and worms are dogs. Gary is SpongeBob's playful pet snail and loves to play with him a lot. The only word he usually says is "Meow." In some episodes, he says something different besides "Meow," like in the episode "Sleepy Time" when he can talk in complete sentences.
He has a pink shell with a red swirl and purple dots on his shell. Gary generally shows little interest in what SpongeBob does, though he will pay more attention when SpongeBob gets him food, a new toy, or plays with him. Gary is never interested in taking baths, and will fight SpongeBob for the bath, as Gary is supposed to be like a cat (which stereotypically cats hate water).
