Larry 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."
Larry 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. His attitude is also not the best.
Larry is the second pet that SpongeBob brings home after Gary chooses to live with Patrick after the worm, Rex. One of the first things SpongeBob does with Larry is feed him (giving him Gary's food bowl, crossing out the "G" and replacing it with an "L"). However, Larry hisses at the food and a frightened SpongeBob takes it away. A little later, SpongeBob prepares himself to go to sleep and had put a bunch of newspaper on the floor for Larry to sleep on. However, Larry hisses and rips up the newspaper and takes over SpongeBob's bed, forcing him to sleep on the floor.
The next day, Larry watches television until SpongeBob interrupts him with a snail joke. Larry isn't amused by this joke and angrily hisses at SpongeBob, before leaving and probably completely abandoning SpongeBob like Rex did to him. It is unknown where he went afterwards.
In "Gary's New Toy," when Gary hisses at the end, he looks like Larry.
His name is usually spelled with two R's, including in the credits. Gary's food bowl only has one R, and SpongeBob didn't add another when he changed it to be Larry's, likely because it would look too crowded.
He looks similar to Larry Luciano, as they both have the same color palette.
