Snail Bites are a brand of snail treats that only appear in the episode "Treats!"
They are a light brown brand of snail treats that are addictive to snails. They are contained in a light teal box that has a yellow circle on it. In the circle is a picture of the treat, and above the circle, it reads the product's name in red text. They would do anything to get a Snail Bite. They are manufactured by the Snail Bites Factory. They were later sold out due to many people buying them for their snails.
Role in episode
SpongeBob first sees them on a commercial at work. He then buys them and brings them home for Gary. The latter is instantly addicted to them, and he likes them so much that when he eats enough, SpongeBob makes him do tricks for them. After Gary ate the whole box in one day, he started meowing for more. SpongeBob couldn't sleep, so he went to his local pet store and they were all sold out.
SpongeBob then went to every pet store in the ocean to look for more Snail Bites, but none had them, as they were all sold out. Because he could not find them in pet stores, SpongeBob went to the factory where snail bites are made to see if they had some. They do not have any, and SpongeBob explained to Gary that there are no more snail bites and that there never will be. Consequently, Gary doesn't stop meowing.
SpongeBob looks to Patrick for advice, and he tells him that he needs to say "no" to Gary. SpongeBob tries this and Gary stops meowing immediately. At the end Patrick was eating the last known box of Snail Bites and, after they were all gone, Patrick started acting like Gary.
Snail Bites also seem to be filled with ingredients like catnip, a plant that attracts cats.
