Later in the episode, upon catching the suds from leaving the freezer open overnight, SpongeBob hires Patrick as his doctor, though Patrick does not help manners and performs many nonsensical acts on SpongeBob that have no positive effect on his illness, one of which is spreading Sea-Nut Butter on the soles of his feet and sandwiching them between two slices of bread.
Patrick, as his eponymous superhero alter ego, spreads a P-shaped Sea-Nut Butter initial on his stomach to reflect his alter ego.
Mini SpongeBob tries to open a jar of Sea-Nut Butter, but struggles since he only has one arm.
