Appearances
They make their debut in the episode Chocolate with Nuts. Both SpongeBob and Patrick evidently hate the bitter tasting chips.
Advertising and Marketing
It is shown that they "stretch the truth" so people could buy their chips. This inspired the two salesmen, SpongeBob and Patrick, to use this strategy which actually became successful. Since the company was so successful, it spread its products into other places. They used billboards to advertise their product.
