Role in series
It first appears in the episode "Suds" when SpongeBob makes himself a sea-nut butter and Jellyfish Jelly sandwich as a midnight snack. Later in the episode, upon catching the suds from leaving the freezer open overnight, SpongeBob hires his best friend Patrick as his doctor and trusts him to cure him of his condition, though Patrick doesn't help manners and performs many nonsensical acts on SpongeBob that have no affect on his illness, one of which is spreading sea-nut butter on his feet and sandwiching them between two slices of bread.
