Sea Biscuits are a food item that appear in the episode "My Leg!"
They are average chocolate chip cookies that come in a bit 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.
