It is a small candy bar that has a red wrapper with a light blue banner on it. It has the word "kelp" written in the center in light/electric blue text. When it is seen from afar, the text reads "goo" instead of "kelp."
He then notices the snack machine from across the street and goes toward it to get some candy, but every time he does so, the bus leaves. SpongeBob eventually tries to trick the bus by not getting the candy bar, but fails, and one of the local Rock Bottomites takes SpongeBob's Kelp Nougat Crunch bar.
