Sea Biscuits are a food item that appear in the episode "My Leg!"
They are average chocolate chip cookies that come in a dark green box, with the front, back, and spines being foam green and the top and bottom being lime green. The food's name is imprinted in red text within a slanted yellow rectangle on top of the cover, which is outlined by a red line. Below this, there is an illustration of three Sea Biscuits. The spine of the box depicts a light blue rectangle.
Role in episode
A little girl scout walks up to SpongeBob, Patrick, and Fred and asks them if they would like to purchase a box of Sea Biscuits. Patrick then swipes the box away from her and claims it as their weapon, only to have his leg injured by the girl for his actions.
Despite being called "Sea Biscuits," they are actually cookies.
