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 against getting in the bath.
Gary the Snail is the pet snail of SpongeBob SquarePants and a cousin to Patrick Star. Snails are the underwater equivalent of cats in SpongeBob SquarePants, so Gary meows and purrs (as seen in the episode "Dumped") like a cat. 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.
