Patrick's skin pouches are parts of Patrick's skin. They appeared in two Episodes: The Battle of Bikini Bottom and Stuck in the Wringer. In The Battle of Bikini Bottom, SpongeBob takes off Patrick's skin that looks like a jumper with a tooth brush and old dirty stuff on it. In Stuck in the Wringer Patrick looks for Forever Glue, and then you can see Slick Stuff, Greasy, Forever Glue and Hair Gel. It is possible that it might have another appearance.
