— Patrick as he reads out the Barnacle Chips billboard, "Chocolate With Nuts"
Barnacle Chips are a popular brand of potato chips in Bikini Bottom. They are known for selling millions of bags a day. Although they have not been physically seen in the series, a billboard for the chips first appears in the episode "Chocolate with Nuts" and later reappears in "Burst Your Bubble."
The bag is orange-red with white edges with capitalized light green letters that say "Barnacle Chips." The billboard has pink and light purple bursts. Both bursts have blue capitalized letters. The pink one says "Eat" while the purple one says "They're Delicious." Their logo is a portrait of Barnacle Products Incorporated's mascot, Mr. Barnacle. In the logo, Mr. Barnacle is wearing a black cape and a black top hat with a red band.
Advertising and marketing
It is shown that they "stretch the truth" so people would buy their chips. This inspired SpongeBob and Patrick to use this strategy which actually became successful. Since the company was so successful, it spreads into products into other places. They used billboards to advertise their product.
