Canned Coral
Canned Coral is a type of food in Bikini Bottom. Patrick probably eats this on a regular basis since he was shown to have only the Canned Coral in its respective episode. This food is only seen in the episode "Rise and Shine".
Looks
On the tin wrapping there is a picture of a coral plant, and beside it it says "Great taste in a can" which might be the slogan.
