Lary the Snail is a stray sea snail with a bad attitude that SpongeBob had brought home from the pound after Gary had chosen to live with Patrick instead. He has first appeared in the episode, "Dumped."
Lary has very thick and bushy black eyebrows that resembles Udon's eyebrow on his head. He hates sleeping on newspapers on the floor and would rather sleep on a bed. He hisses when he does not like something, or he does not get his way.
Lary was the first snail that SpongeBob bought home after thinking Gary went to live with Patrick. One of the first things SpongeBob does with Lary is feeding 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 fightened 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 his owner to sleep on the floor. The next day, Lary was watching television until SpongeBob interrupted him with a snail joke. Lary isn't amused by this joke and hisses at SpongeBob before leaving (presumbly out of the house).
