Kevin's Ointment appears as a small, white tube with the words "Kevin's Ointment" on it. The ointment itself is pink in color, just like the color for the common species of jellyfish. It shares a resemblance to real-life items of the type.
Kevin advertises his ointment during the Biannual Jellyfish Convention. It is seen on various banners throughout the convention. Kevin also uses his ointment several times off screen to heal himself of jellyfish stings when he is giving SpongeBob his "initiation." Kevin's Ointment makes its first appearance after it is seen under a bush.
