A medium-sized bag of Kelp Jerky.
Kelp Jerky is an underwater snack which resembles and tastes like Beef Jerky. If cut in half, they resemble tannedteeth. They are the result of burning and curing kelp. It is a parody of Beef Jerky. They appear in the episode "Porous Pockets" , when Patrick finishes a bag and then says "I'm gonna go get something to eat." They also appear in "Sun Bleached" when SpongeBob is trying to get a tan.
