Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better. a.
