The box is a light lavender color with two dark red stripes across the front. There is a small yellow circle seen on the cover with a picture of a snail. Between the stripes, some blue text ("Snail Fud") is seen. In "Procrastination," it is shown that there is much more food in the box than there seems to be.
It is unknown why SpongeBob did not feed Gary Snail-Po instead.
