Cream Soda is an antibiotic drink made by stealing water from the Soda Seas and adding regurgitated sugar.
It has been Rockhopper's favorite drink since childhood, as was actually thrown into a barrel of cream soda when he was 18 days old. He has been addicted to cream soda ever since. In 2004, he thought a barrel of hot sauce was cream soda, and he gulped it down, and he vomited it all over the ice berg. Rockhopper not only uses cream soda for drinking, but he uses cream soda for washing and trimming his beard, bathing etc. Rockhopper even said, "Nothing matters to me if Yarr disappears, but I will cry if I don't find cream soda.".
