Lary the Snail is a stray sea snail with a bad attitude. SpongeBob buys him from the pound after Gary had chosen to live with Patrick and Rex had run away. He first appears in the episode "Dumped."
Lary has very thick and bushy black eyebrows that resemble Oscar the Grouch's eyebrow on his head. He has an olive brown shell with light brown dots, a purple curl on his shell, and a pink and jade green underside. He hates sleeping on newspapers on the floor and would rather sleep on a bed. He hisses when he does not like something or when he does not get his way.
In the episode "Dumped," Lary was the first snail that SpongeBob brought home after Gary chose to live with Patrick. One of the first things SpongeBob does with Lary is feed him (giving him Gary's food bowl, crossing out the "G" and replacing it with an "L"). However, Lary hisses at the food and a frightened SpongeBob takes it away. A little later, SpongeBob prepares himself to go to sleep and has put a bunch of newspaper on the floor for Lary to sleep on. However, Lary rips up the newspaper and takes over SpongeBob's bed, forcing him to sleep on the floor.
The next day, Lary watches television until SpongeBob interrupts him with a snail joke. Lary isn't amused by this joke and hisses at SpongeBob before leaving.
In the video game Lights, Camera, Pants!, he is a pet of the Sneaky Hermit.
