Due to SpongeBob's neglecting to feed him, Gary runs away from home and is taken in by Granny after the latter mistakes him for one of her deceased pet snails, Miss Tuffsy. Unbeknownst to Gary, she plans to fatten him up and eat him. Despite Granny acting kind towards him, Gary finds out that she has eaten other snails after opening her closet. As a result, Gary runs away back to Bikini Bottom for SpongeBob and Granny goes out to look for him, offering a plate of cookies. Gary runs into an alley snail he met earlier and pushes him into the sidewalk for Granny and she takes him instead.
