Kelp Nougat Crunch appears to be a small candy bar that has a red wrapper with a white banner on it. It has the world "kelp" written in the center in light/electric blue and it is from the Rock Bottom Kandy machine. Kelp Nougat Crunch resembles the wrapper and appearance of a mini Snickers or some other brand of chocolate.
Role in series
After waiting for the bus to get from Rock Bottom back to Bikini Bottom, SpongeBob eventually grows hungry. He first eats candy from his Glove Candy Dispenser he got from Glove World!, but he spits them out due to their disgusting flavor.
He then notices the snack machine across the street and goes toward it to get some candy, but everytime he does, 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. As the Rock Bottomite runs away, SpongeBob shouts "Hey, that was mine!" at him, while several buses pass the stop.
