Sponge Bob notices that his pal Gary is suffering from slimotosis,
which occurs when the shell develops a nasty slime and gives off a
horrible odor. 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 for 1 week and having him drink Dr.
Kelp. After a week of treatment, the slime is gone and Gary’s shell
smells better.
