Sea-Nut Butter is a common food in Bikini Bottom. It has appeared or been mentioned in several episodes, starting with "Suds."
The jar of Sea-Nut Butter is dark brown with a white label. The words printed on the label simply read the condiment's name in big red capital letters.
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.
It is mentioned several times in the episode "Pranks a Lot" when SpongeBob hands Patrick a fake can of Sea-Nut Butter which he believes to be real. It turns out to just be a gag can where springs bounce out when you open the lid.
