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 "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).
