Jerry is a very small, realistic-looking snail. He only appears in the episode "Dumped."
In the episode "Dumped," SpongeBob compares him to Gary the Snail and Lary the Snail, saying, "And Gary and Lary are really different than...Jerry." while taking Jerry out of his pocket.
- Jerry closely resembles the snail species known as Helix pomatia, also known as the edible snail, the burgundy snail, or the roman snail.
- It is unknown if Jerry is SpongeBob's pet or not, because SpongeBob is never seen taking care of him.
- It is possible that Jerry is a plastic snail, as he is kept in SpongeBob's pocket, and shows no sign of being alive during his brief appearance.
